Hello Arturia team,
When I control the microbrute with the beatsteps cv/gate signals the pitch is transposed 3 octaves up.
When controlling it via midi everything works fine. Can you tell me what's the problem and how to solve it?
Today I also had some other trouble with this setup (using midi). This time i think it's the microbrute, but I'm not sure:
When there was no sequence running and I tried to start the sequence while I was adjusting the pitch of one step, the microbrute would hang up on this tone. All notes off command didn't work, i had to reboot it.
Thanks,
Chris

Even if the Beatsteps CV out is only connected to the Microbrutes pitch input and no sequence is running everything i play on the keyboard is transposed severals octaves up!
-
Does the MicroBrute have some settings for how it will be controlled by CV?
I know that when sending CV via my Elektron A4 to my Mg SlimPhatty I had to correct the voltage in order to get it to scale correct. Might be the same with the Micro Brute
-
@vegradd:
According to some videos I saw, it should work without voltage correction.
-
I think I was able to evaluate the problem:
Apparently there is a constant voltage being sent out of the CV output. Even if no sequence is running.
When a sequence is running, the correct control voltages are added to this constant voltage, which causes the higher pitch.
-
Hmm... a little bit odd still...

Hi just bought the beatstep with the ideal of a running a Mg slim phatty with the cv /gate option so I can run something else in control mode thing is I to am getting the same problem its outputting at a to high pitch than I want works fine with midi ive read different synths require different voltage is the Mg slim phatty one of them and is that it do I have to use the midi option shame really I looked forward to running 3 things cv for my Mg midi for my korg x50 and usb for pc can anybody help please....

Have you tried turning the autotune of the Mg off?
-
hi m8 thanks for the reply I tried with autotune on/off from what I can gather its beacause the aturia beatstep is outputting a certain voltage and so is the Mg s/p but different so the difference is being the higher octave works fine in midi just wish I had researched this before purchase if they implement some kind of tie like reason 7 matrix I will be happy to run in midi if no tie perhaps regretting purchase.

This might seem an odd question but - what do you mean CV pitch IN on the microbrute? As far as I can tell there is only pitch OUT. There is however gate in.

The pitch input is part of the mod-matrix!

I can confirm that the basic CV output is too high and the gate is too low… Tried it on a MiniMg and I have to have all 3 range switches set to 32'. Even then, it's still too high and I'm having to feed it through my modulars CV adder (along with a -3V source) to reduce the output. Not ideal but it works. Also, the gate won't trigger my ARP… That has to be processed via the 2600's amp to get it to a decent level
Hoping Arturia can fix this via a firmware update.

Oh right!
I tried that too but unfortunately I'm having the same problem as everyone else. Weird that Arturia's products work terribly together.

Hello,
I got the same problem hooking up my Minibrute with the Beatstep.
It first didn't work over Midi. and it's pitching 3 octaves higher with the CV IN.
And it even makes sound while the Minibrute Master Volume knob ist turned down. Like a kind of selfoscillating sound.
I don't know, why Arturia products didn't match up this time....
Somebody got a solution yet?

Hurray iam not on my own wasn't to sure if it was me only got a Mg slim phatty and use it by usb so kinda new to this < bar using reason>

I've just had a thought - We're dealing with digital here, powered from 0-5V via USB. Somewhere along the line Arturia must have decided on a happy medium (literally) to decide where the central voltage is to allow the sequence to be programmed up or down, in the Beatstep's case, that's a +4V default encoder output.
Analogue sequencer pots generally have a centre position of 0V allowing for a -Ve and +Ve voltage swing... Beatstep obviously can't do this, although it would help a little if the lowest output voltage was 0V - Maybe they couldn't do that for some reason due to the design?
There you have it… problem explained. Arturia, can I have a job please ;D

Not sure if this helps anyone, but just in case it does.
I just got a Microbrute and Beatstep this weekend and was excited about playing with the CV functions of the two. I was initially frustrated when I tried to hook the two of them together, as I experienced the three octave behavior noted here. I did some testing and at least got a suitable workaround. These are just my observations.
It's important to note that the "Pitch" function on the mod matrix is not an "objective" CV input. Its output is tied to the keyboard of the Microbrute. The initial relative pitch of your sequence coming in to the Microbrute from the Beatstep can therefore be affected by it.
If the Microbrute is powered up with the Beatstep already on and connected, my sequences will start in a low register. The second I hit a key, however, the pitch gets shifted way up. From this observation, my guess is that it has an initial default power-up setting, but after that, it is responding to the last key pressed (and actually apparently playing a note three octaves above that).
My process is to either power-up with the Beatstep on and connected (and not touch the keyboard) OR start with the Beatstep "pitch" input unplugged, shift the octave down three octaves (you can do three octaves even though it looks like it might only do two) and then play the lowest C on the keyboard. Then, plug the CV out of the Beatstep into the "Pitch" in of the mod matrix. The pitch should be shifted down now, because it is basing everything on the last note played.
You can also play any key while the sequencer is playing and hear the shift, but note that the octave shift will only occur in the sequence if you hit a key after shifting the octave down (just pushing the octave +/- keys doesn't do anything).
This may be really obvious to most of you, but I thought it might help someone.

I was having the same problem - beat step connected to a Mg Little Phatty. I discovered that while I had a sequence running, I hit a low note on the keyboard and it transposed the sequence - problem solved.

This helped me! Thanks. I'm running an old Arp AXXE with my Beatstep Pro and I was having a hard time figuring out why it was running several octaves high. With the power up sequence that you mentioned, I've got it running properly and can play the fat low octaves. Thanks!
-
WTF Arturia. You actually make publicity for the beatstep pro with 8 minibrutes and microbrutes connected, as if they were made for each other, and we have to wait to get both (or the three of them) to notice that they are completely incapable of working fine together.
You are actually promoting things your products can't do and don't even give feedback when we don't understand what's happening.

Connect the Beatstep to the Microbrute, only then turn on the Microbrute. The notes from the Beatstep will play at the right pitch. If you accidentally press a Microbrute key and the sequence is transposed, transpose the keyboard to Octave -3 and press the lowest key (C). It will transpose the Beatstep sequence back to its normal pitch.
