pitch -1 semitone
« on: July 13, 2019, 06:59:42 pm »
Hello... since 1 week ago more or less I notice that my MB when it works is out of tune,
I tune it pressing KBDTRACK+Panel, and it is tuned well but in - 1 semitone,
 can you tell me how I could raise that semitone so that in transpose 0
is tuned like the other synths?

Greetings Neosynth

I had a similar issue. What I did to fix it was to trick the computer.
 If you have the same issue as I did, the Matrixbrute thinks it is in tune.
 Take a CV output from something, let's say osc 1 supersaw and input the CV into the osc pitch "CV in" to push the osc that is -1 semitone down -1 semitone further.
 Press hold note,  hit a note, then run the autotune sequence. You'll hear the oscillators moving around to find tune. If all goes well, when tuning is done, remove the CV Jack's and all should be in tune.

Goodluck!

Thank you very much standingwave for your response!

When I arrive at the Studio, I will try to apply your instructions.
Best regards Neosynth ;)

A very long shot and most probably not the case, but if we're talking exactly one semitone, is the Fine Tune knob centered and not accidentally left fully CCW?

Otherwise, standingwave's workaround is a clever one, or alternatively you could use the Fine Tune knob to manually tune it a semitone up until this problem is resolved ('cause it should NOT be like that...).

 Hey Neo
 I assumed you were saying an oscillator is out of tune by -1 semitone. If it is all oscillators, definitely check the fine tune knob first!

 It's less likely the same problem as I had if it is all oscillators. A good next step, assuming the master tune knob is correctly positioned is a firmware reinstallation.

 Good luck!

Oh, my God! Thank you for your help.
I never play the Fine tune potentiometer, and from what you see the other day, I touched that potentiometer, and with so many .... I did not realize!! and I was going crazy.

Thank you very much Dr Justice and standingwave for your help, it has been crucial to be able to solve it.

Thank you Neosynth!!

It's nice when the simplest solution is the one that works!
 Cheers.
