New P600fw alpha (march 1)

I didn't have much time to dedicate to my synthesizer projects these last months, but here's a new alpha of P600fw with the following changes:

- Fixed broken exponential envelopes interpolation (was causing stepping).
- Removed MIDI soft-thru (it wasn't an intended feature).
- Added 1/1 and 1/2 arpeggiator external clock ratios (usefull for tape sync).
- Made minor tweaks to the tuner.

  1. I installed the 03-2014 version but the problem of intonation jumping in a totally random
    remains. I noticed that setting the oscillator A level to zero, or putting oscillators in sync mode the problem does not occur, then the oscillator A is the culprit?
    Do you think you can solve?
    Thanks again for all the work you have done and are still doing it.

    1. Well, this is probably a tuning problem, ie one or more voices having osc A out of tune.

      Maybe You should try to do the scaling procedure with the Z80 (as described in the original owner's manual) if You haven't already. This often helps the P600fw tuner to get proper tuning.

  2. Hello, I am Hector Grisi, I've already commented on the recent version 3.1.2014 regarding a problem tuning of the oscillator A jumping randomly, and I followed your indication to the procedure of scaling the voices with the Z80, but when I reassembled the Z80 processor the prophet 600 does not give any sign of life, the panel does not turn on no led and at the audio output is heard only one fixed sound consists of many frequencies, know how to give me a help? (Note: reassembling your firmware 17-03-2014 (synth works!)
    Thanks again
