Title: Control voltage input specs?
Post by: leighmarble on March 01, 2013, 08:40:20 pm
Hello,

Is there anywhere that the Minibrute's Control Voltage input specs have been published? I've looked, but can't find this info anywhere.

I'd guess that the Pitch input takes a 0-10V range (1 V/oct). However, what about the Filter and Amp CV inputs? Same range?

Also, do negative CV values get added to the internal values, or are negative values ignored?

thanks,
Leigh

C'est du 0-10V mais cela accepte aussi des tensions négatives jusqu'à -5V.
It's of Anafrog Forum ( http://forum.anafrog.com/phpBB/viewtopic.php?f=26&t=6151&start=2460 )[/font][/color]

Thank you for finding that information, tertior.

So, the final answer (from Yves himself): the CV input range is from -5 to 10V.

The way he said it was "0-10V but it also accepts negative voltages up to 5V", so that sounds right, unless he was hinting that negative range is treated somehow differently...

cheers,
Leigh

Maybe he's just saying that the negative voltages might not work as expected, but will not damage the device.

By this I meant, that the normal range is 0 to 10V but using voltages down to -5V will work too, for example the VCO will run like a very slow LFO, or the filter in LP mode will mute all sounds. A negative voltage (limited to -5V) will not harm your MiniBrute.

Thank you for the precise answer, Yves!

Is the Gate input also 0-10V? I recently built a Trigger Converter circuit, using this schematic (http://user.xmission.com/~dingebre/Trigger_Converter.html), which has a V-trigger output at 12V. I'm pretty sure that's not going to break anything, but just wondering what the ideal gate voltage would be for the Minibrute.

cheers,
Leigh

The MiniBrute expects 0/5V GATE signal but I think it can handle 0/12V too but this has to be confirmed by Bruno though...

indeed 0/12V will be fine.

Sorry for resurrecting  this old topic but I'd like to ask if 5 volts are enough to trigger microbrute envelopes through gate in
Thanx in advance!

Yes 5V is enough on MiniBrute, MicroBrute and MatrixBrute
