Title: Modulation Wheel
Post by: mineral on November 10, 2013, 05:43:08 pm
Hello,

I tried to get support but did not really work out till now.

I've noticed that my microbrute (and probably others too) only uses the half of the range of the modulation wheel.
If you watch carefully a lot of videos on the internet show the same behavior of the microbrute.

It does only change values in the lower half of the movement range of the modwheel, from the middle to the top it has one single maximum value.

I noticed this while assigned to the filter cutoff but than I measured the amplitude of the LFO and it's the same.
Even the MIDI CC which it transmits is already 127 when you reach the middle position of the modwheel and does not change in the upper range.

Can I set it somehow without soldering?
It seems to me that I will not be fixed with a firmware update but more like a wrong value resistor soldered on the circuit board.

Many thanks.

Best regards,
Vic

Same here. It's easy to work around, but I'm hoping it's something that can be fixed in a firmware update... Is the mod wheel range one of the digital bits? :) Even better, it'd be awesome to be able to set a curve for it: linear, curvy, etc.

I just replied to one of your support ticket. I guess it's just a bad calibration at the factory. Please let me know if you have the same behavior on Midi.

If so I will upload the calibration software plus procedure explanations, as soon as possible.

Please give a try to the enclosed Calibration TechNote. As it's supposed to be a production tool, it's only available on Windows...
(you need to be registered to see and download it)

Hello Bruno,

I tried it and the software tool confirmed a successful calibration but the behavior of the modwheel did not change.
I've checked it with midi-ox and in the middle position it already reaches cc1 and cc33 (hex 21) 127 (hex 7F).

I've performed also the firmware update and tried to calibrate it again, switched off and back on again but it all didn't help.

Do you have any further suggestion?

Many thanks!

Best regards,
Vic

Hummm.
Ok so first I need to be sure the calibration is properly applied by the machine.
Can you do a second test:
1/ set both wheel in center position.
2/ Do a calibration process, but when asked to move the wheels, do not. I mean during all the process the two wheels should stay in center position.
3/ Now you two wheels should basically have only two values, you change between them by crossing center position. If they still behave as before the calibration is not taken into account.
4/ If calibration has modified the behavior, do it again but by following on screen instructions.

Please let me know your results at step 3 and 4.

Thanks

Post by: mineral on November 13, 2013, 04:28:08 pm
Hello,

The calibration succeeded. See calibration_middle.png
With proper calibration afterwards see recalibration.png

The modwheel does not transmit any data on the upper range it is already 7F from the middle.

Thank you!
Title: Re: Modulation Wheel
Post by: Bruno@arturia on November 13, 2013, 04:51:27 pm
Ok for the center calibration.
But for recalibration, what are the wheels movements you did on Midi-Ox recording?
Not sure I understood, because, even your pitch bend is not functioning properly(range is very narrow).
mod wheel does not go full range either.

Can you do the following midiOx recording:

1/ pitch bend: start from center position, go to 0, go to max, and release to back to center.
2/ modwheel. start from 0 go to max

please send me theses two capture so I can have a clear understanding.

Thanks for the time you spend on this.

Title: Re: Modulation Wheel
Post by: mineral on November 13, 2013, 04:58:45 pm
No problem.

As you requested the pitch- and modwheel movement.
Note that the modwheel value does not change from the middle position to the top. It just stops at the middle with 7F value.
Title: Re: Modulation Wheel
Post by: Bruno@arturia on November 13, 2013, 05:12:06 pm
Thanks!
ok so unfortunately it does not seems to be a firmware or calibration. So it could the modwheel itself.
Do you have a voltmeter and do you know how to use it?
I would need to get voltage on each of the three modwheel pins.

If you don't have or don't want to use a voltmeter on a opened machine, we will do it another way, no worries

let me know

Title: Re: Modulation Wheel
Post by: mineral on November 14, 2013, 12:38:09 am
Problem solved.

I measured first the voltages on the potentiometers.
Pitchwheel goes from 0 V to 3,277 V.
Modwheel went from 0 V to 1,986 V or to the other pin from 1,295 V to 3,277V.

I've concluded that the shaft might be twisted and does not have the required resistance so I checked it and indeed.
The wheel was force onto the shaft in the wrong position.

After rectifying it I calibrated it again. (now I understand that because not using the full scale of the potentiometer can have a small deviation and therefore you need to calibrate the position)
And it all works fine now.

I would propose some kind of poka-yoke tooling which prevents the wheel from being pressed onto the shaft in the wrong position or to point this failure out on the final inspection plan.

Thank you very much for your support.

Best regards,
Vic

Hi Vic,
thanks for you valuable feedback. It was a complex issue, and it's been nice from you to take the time to investigate it.

I reported your pictures to our factory.
They will setup an additional step in the quality check process, to ensure this kind of miss-mounting won't happen again. And an additional step on the final test, to ensure the modwheel is fully functional after calibration
On my side I'll add the fix description to the mod wheel issue Technote. Do you mind if I use the photos you uploaded on the forum? 

Thanks again to raise and solve it.
Bruno

If we get this problem, should we send the unit back?
Title: Re: Modulation Wheel
Post by: Bruno@arturia on November 25, 2013, 11:14:47 am
you can either send it back for repair, either we can send you replacement wheel cap if you prefer to replace it your self.
But first you need to be sure it's no only a calibration issue. Please Check my older posts in this topic

Hello,
my modulation wheel has the same problem raised on this topic.
Once opened the Microbrute i found the wheel cap was forced in the wrong position by factory, with a broken dent like
in the picture posted in this thread by a user.
How I can ask to the support to send me a replacement wheel cap?

Thanks

Oh I don't believe it! This is now two faults on a brand new unit that I only purchased days ago. What are Arturia going to do to put things right?! We should not be working for you - this is Arturia's job to iron out these faults before they leave the factory!! If I have to send this unit back it will not be at my expense.

Post by: mikoro on April 01, 2014, 10:30:12 pm
I had two issues with the mod wheels which were both resolved by the fix posted above.

-> The pitch bend would "hiccup" downwards (going up slightly before going down).
-> The mod wheel wouldn't react until 90% up, after which it screamed open. It seemed to work like a binary switch almost.

As I said, both issues were resolved immediately with recalibration, I'm super happy.

Is it hard to replace the pitch wheel?

Hi everybody, the pitch wheel on my microbrute is working bad, when I getting down it is working perfectly but when I getting up, it jump down at the biggining of range and jump down at the end of range ... the calibration proccess fix the problem but when I turn off the brute and turn on again, the problem is back again ! How I can fix and save with the calibration tool ? I'm sure it is not an hardware problem but I did the calibration proccess a lot of time and allways the same problem !! help  ???

Post by: vinw on April 13, 2014, 01:11:25 pm
Hello! This is my first post since I bought my Microbrute yesterday.
Both wheels had a problem:
-when bending up, the pitch wheel would shortly pitch the sound down before pitching it up.
-the mod wheel had a kind of glitch/hic-up right after its zero position, as if it were shortly at max position.
Although I have a Mac, I manage to get hold of a PC and applied the wheel calibration procedure: this fixed both issues. unfortunately, when restarting the Microbrute, the pitch wheel still has its original issue (the Mod wheel seems completely OK though :) ).
>> Should I return my unit to my shop?
Or do you think this can be fixed by software?

Thank You! (very frustrating to have that issue since the machine seems great beside those issues, but wheels are fundamental, so this is a blocking issues for me unfortunately)
Title: Re: Modulation Wheel
Post by: c3ll on April 17, 2014, 01:50:38 am
I was experiencing the odd pitch wheel behavior, jumping upon using the UP direction. I updated firmware, and used the windows calibration tool, first not moving the wheels to verify it changed behavior, and then repeating the process following the directions to a tee. Pitch wheel problems fixed!! Everything else on the unit seems fine.

Same thing here: when moving the pitch wheel up, it pitches the sound down in its first half and only then it pitches the sound up. I managed to borrow a laptop PC to do the calibration, which fixed it, BUT…when I power cycle the MB, the problem is back again. Where should I look? Should I just take it back to the store?

hi,

recieved my MicroBrute yesterday- great synth but same issue with the pitch wheel at my machine:

pitch down: everything is fine
pitch up: with the up-moving of the wheel the pitch of the synth goes first down(!), then goes up to the high value (which is defined in the connection software). The same using the MB as a midi-controller. CC pitch-wheel data middle position: 63. When movin the wheel up the cc-value is changing suddenly from 63 to 4 then to 5, 6, 7, and finally suddenly from 7 to 127.

regards,
Klaus

It'd be great if the people of Arturia accessed this thread. I bet there will be more people with the same problem coming here.
I know I COULD take the unit to the store (thanks to warranty) but an official reply wouldn't hurt. Calibration works here, but only until it's powered off and back on again.
Title: Re: Modulation Wheel
Post by: nitrofresh on April 29, 2014, 05:34:02 am
Just got my Microbrute too.
Mine has the same problem with a pitch wheel going up.
Please let me know what to do to fix this issue. Thanks.
Title: Re: Modulation Wheel
Post by: erstlaub on April 29, 2014, 11:43:04 pm
Just to chime in,

My first Microbrute had a dead Sub input on the the mod matrix, replacement arrived today and has the pitchwheel issue. When moving the wheel up the way, there is a notable drop in pitch and then a jump to whatever I've set the bend value to.

I'm primarily on a Mac but managed to get a hold of a Windows machine and running the calibration tool fixed it, sadly only until reboot.

I feel like Arturia are doing their best to make me hate this synth even though I really really really want not to.

Hopefully a firmware update will be along soon to fix it, seems to be a whole lot of people suffering from it atm.

Boooo.

Title: Re: Modulation Wheel
Post by: nitrofresh on April 30, 2014, 06:48:33 pm
I tried re-calibration that Bruno posted on the first page of this thread.
It worked... but after re-booting the machine (turning the Microbrute off and back on), the problem still existed.

I have a problem with a pitch wheel.
My keyboard playing requires a lot of pitch wheel performances, and this problem needs to be fixed right away!!!

Very very disappointed, but I hope the guys at ARTURIA are now paying a very special attention to those with this problem.
Title: Re: Modulation Wheel
Post by: ben arturia on May 02, 2014, 11:34:10 am
We have been trying to reproduce this problem here with Bruno.
No problem occurs wheel calibration is still there even after reboot...
Did you update with last firmware version ?
What is your OS ?
Are you sending any MIDI message to MicroBrute while calibration is running ?
Title: Re: Modulation Wheel
Post by: erstlaub on May 02, 2014, 01:24:27 pm
Running latest firmware version on the Micro, no software that could be sending usb midi signals open, no midi or other signals physically patched in during calibration, was calibrated using my gf's Win7 (I think) machine. (it would be SUPER useful if the calibration tool came in osx flavour too as I don't always have access to a PC).

Calibration runs without any problems, fixes the problem and then once you turn off and on the power the problem persists.

I tried multiple times incase it was just bad luck, I even tried updating the firmware once it'd been recalibrated incase that was the only way of making the fix stick.

Still exactly the same issue.

erstlaub :
Your issue is really really weird. Calibration info is stored in a flash memory. If it works after calibration it should work even if you power off/on the machine.
Please could you give an other try on another computer ?

mediaklaus :
You should make a calibration if you have any modwheel or pitch wheel pb. Sorry the soft is PC only...

Post by: erstlaub on May 05, 2014, 11:35:00 am
I don't have access to another computer so I can't, sorry.

I'm not the only person whose calibration doesn't seem to be sticking after a power cycle. Hopefully someone else will be able to help you work out what's happening.

the fact that some people having this problem with brand new (!) devices shows me that there ist either  a hardware problem with the flash memory or a software problem with the calibration tool (data is not saved correctly to the memory)

So, what else is stored in the flash memory? The sequences? The octave setting (which ist resetted at my device after shut down)?

Hi folks. I just took delivery of my Microbrute. Loving it, but I have the same problem with the pitch bend and mod wheel as others have described. Down range on pitchbend is fine. Up goes up then down. Mod wheel sensitivity seems uncalibrated.

So, I registered the MB on the Arturia site but I do not see any calibration software there (or instructions apart from in this thread). Where do I find the calibration software?

Kind regards

Derek.

Interestingly, after several power recycles, and then leaving the Microbrute on for several hours, the calibration "stuck" and survived the next reboot.

Still not how it should be of course, it's a "this shouldn't happen" situation. But, hopefully Arturia will get a permanent fix out. Appreciate they're looking at it now.

I don't have the same issues as the users above me, but I do have a pitch wheel that doesn't seem to do anything at all. I'm hoping it's a switch that needs to be turned on that I'm missing, but I don't think it is.

Post by: mrphosphorous on May 25, 2014, 11:45:13 pm
I've got a similar problem with the Pitch Bend wheel, there's a dead zone from just above the centre to right near the top, during which it drops the pitch by a fixed amount. 

Using the calibration tool fixes it as long as the power's on, but on rebooting it reverts to how it was before.  Changes made using the Microbrute Connection software are retained OK, it's just the wheel calibration that is not stored properly.

Well, I tried that (on a Mac here) – I updated the firmware. However, that doesn't calibrate it on a Mac, of course. So I don't know if it fixed my pitch wheel problem (described it on page 2), so I dunno if it works.
Is there a chance you could do the calibration software for Mac, too?
Title: Re: Modulation Wheel

After updating your firmware to the latest version you absolutely need to calibrate again the pitch bend wheel.

Post by: steveurick on July 17, 2014, 04:08:43 am
All Right! I did it and it fixed my pitch wheel problems. (For the benefit of others, my problem was that slight movement from the centre position in either direction would result in a sudden shift of pitch to the degree of the total range of the pitch wheel. If I moved it a little more it would revert to the original pitch and then after moving a bit more revert to normal pitch bending.)

Thanks! This was a lot less trouble than returning the unit! I am back in love with it!

Hello all,

I'm a newbie here and just purchased a MicroBrute last week.  I've noticed that the modulation wheel is occasionally popping and clicking.  I'm not sure whether this is a hardware or software fault.  I've updated the firmware but the problem still persists.  Does this sound like a mod wheel recalibration fix?

Unfortunately, I don't have a Windows PC to run the recalibration program to eliminate any potential software issues.  Is there a Mac based calibration programme available from Arturia?   

Thanks

Hello !
i just bought a brand new microbrute, and i noticed the pitchwheel acted kind of weird. No problem when you go downward, but really weird when you go upward.

Here is some stuff i recorded to show the behaviour. You can hear that it's totally fine when going downward, and then i try upward and you hear the "STEP" effect.

i tried the Wheel calibration patch, but no changes at all.  :-\

what should i do ?

thanks!

Post by: MozartVonRobot on November 28, 2014, 05:33:46 pm
I just bought a slightly used Microbrute, and I had pretty much the same problem as the poster just above me. Pitching down worked fine, but pitching up made it step down before stepping up. I ran the wheel calibration software and it didn't work. Then I closed the calibration software, rebooted my microbrute and tried the calibration software again. It worked, and my wheels are now working fine!

EDIT: ...but now the sequencer is not working.
EDIT2: ...got it to work by fiddling with the clk/gate switch in the connection software. All is well now, it seems.

Personally, i just sent back the unit back to the shop as no one answered me here.

So, the shop guy gave me a brand new one, but i asked for testing it. AND THEN, same problem... So the synth is going to get repaired and i just bought some new synth i can't use for i don't know how many time.

Quite a bummer, if you ask me.  :(

I had this weird problem with my pitch wheel as well. When I fist got the MB the wheel would work fine when bending DOWN but when bending UP there would be this weird note-jumping-behaviour described by some people in this thread.
I have tried a lot of things and couldn't find a solution but what is described here on page 4 of this thread has fixed my problem!

Thank you Bruno & Ben.

PS: Did it on VirtualBox as well

Could'nt fix the problem with all the solutions evoked, so the shop took it back for Repair 3 days after the buying.


THE UNIT IS STILL GETTING REPAIRED after 2 Months. For a minor problem that is certainly known by Arturia, this long amount of time truely sucks.

Seriously...


(oh and i live in France, so buying French bla bla bla)

Thanks, @Bruno and @Ben!

I too had the stepping behavior on upward pitch wheel movements.  I downloaded the zip file from the link in Ben's post, installed the new OS version, ran the calibration tool, rebooted, and ... pitch wheel is working normally !!!  What a relief, thanks again - i'm very happy with my tiny brute!

I must say that it took quite a bit of digging (via internet search) to find this solution.  And ironically it comes in the midst of a thread titled "Modulation Wheel."  There are a couple of references to the "latest firmware version" but nowhere does it give the specific number (so i spent some time spinning my wheels with version 1.03.2, which is the latest available from the Resources page for the MicroBrute on the main Arturia website).  Seems like there must be a better (more obvious) way to make this fix available; i bought my unit in August, so apparently there are still units in dealers' stock that have this same problem.

I will make the link known to Arturia Support (who knew about the calibration tool, but were silent as soon as i mentioned that the fix did not persist past reboots).  Hope fully that will make it easier for others to find this great fix.

Once again many thanks to Bruno and Ben for persevering to make this new OS version 1.03.3 available to us all!

Any change to put the link up where the 1.03.3 firmware is?

Arturia support site still shows 1.03.2.

Found it, 1.03.3 firmware. However, that is also from last year, and in size much smaller than 1.03.2, so I did not dare to install it.

Since my Microbrute SE is working fine, I guess I use the slogan, if it works, don't fix it.

Does anyone knows why the calibration won't stay after reboot?
I've had problems like many others and with Firmware 1.0.3.2 and the calibration tool I'm able to make the Pitch Wheel works as it should but I keep loosing the calibration when I turn off the unit.
Is it a memory problem?

Please help me with this!

Hello, i had this problem with my Arturia Microbrute (new, received today). I just did a calibration test with the utility that Bruno provided, and all works now !!

I enjoy this product, thanks to Arturia for distant support on forum.

Just applied this to my second-hand microbrute and fixed it! Happy now. I can confirm the calibration software works fine in Windows 10. Thanks Bruno and Ben and all who helped Arturia get to the bottom of this. I'd been assuming this was a dirty pot on my pitch bend wheel and opened up the microbrute, looked at it with a multimeter and couldn't see a problem. Then I started looking at schematics before checking this forum :)

Looks like it's been quiet here for a while, but I thought I'd ask anyway:

My MicroBrute pitch wheel had the problem of jumping down then going up when I bent upwards - I initially thought this was the pot, so replaced it, which didn't work, then I found this thread and the calibration software, which stopped the jumping problem, but now it doesn't work as a pitch *bend* just a shift. It's either all up or all down, rather than bending. I've tried calibrating it again a few times, but no luck.
Any idea what the solution could be?

My pitch wheel was jumping, but I changed the bend value from 12 to 6 in the connection software and now it's working.

Hi everybody, the pitch wheel on my microbrute is working bad, when I getting down it is working perfectly but when I getting up, it jump down at the biggining of range and jump down at the end of range ... the calibration proccess fix the problem but when I turn off the brute and turn on again, the problem is back again ! How I can fix and save with the calibration tool ? I'm sure it is not an hardware problem but I did the calibration proccess a lot of time and allways the same problem !! help  ???

this is the problem i'm dealing right now! Calibration helps! But only before first restart. After restart pitch wheel (up position) faults again

Oh, thank God:) i think now it works for me too:)
The problem was in a firmware version. I thought that i have the latest one. 1.0.3.2 (as it supported on Arturia's website).
But i downloaded the files uploaded here https://owncloud.arturia.net/index.php/s/Br2HYsOOsXoY40q
And there's a newer version 1.0.3.3. I updated firmware, ran calibration test and after restart pith wheel works fine.
I will test the synth from the begining now. Hope not to find any more faults

I tried this but no joy.

I hadn't thought to check it over midi before now - it's doing the jump on midi, too.
So, I've calibrated, tried changing bend range, updated the firmware, calibrated, tried changing the bend range, replaced the pot, calibrated again, tried changing the bend range, updated the firmware again and calibrated again and changed the bend range again, and still it jumps. This is really bugging me.

I received my MicroBrute from Amazon yesterday evening (April 27, 2019) and I'm currently experiencing a couple issues. I opened a Technical Support ticket earlier this morning, but wanted to post an update here since the information in this forum immediately solved one of my issues. Also, I updated the firmware to version 1.0.4.114 immediately upon receiving the MicroBrute using MIDI Control Center version 1.8.0.1031 (formerly known as MicroBruteConnection).
