ASynth bug.

[arguru]

Hi Antti
Just spotted this one:

http://psycle.free.fr/Arguru/asynth_fm7 ... cksize.mp3

It shows clearly that ASynth it's not respecting deltaFrame member of vst-event structure very well, so it sounds out-of-timing using not-considerable-big process blocksize (1024 is not that much, taking in account that most hosts using non-asio drivers set about 2048 or even more as process-blocksize).

The first example is Asynth first patch iirc and second is FM7, wich handles events fine.

Host enviroment:

Samplerat: 44100 hz
Blocksize: 1024 samples

This is strange. ASynth uses almost exactly same event handling code as Augur for the polyphonic mode, so it Should handle the timing just fine. There is a limit on maximum buffer size but that is around 8000 samples. I will recheck the code and make a debug version for you that outputs the deltaFrames etc to a text file.

When you already are bugfixing, maybe you can check the issue, that asynth produces no sound in Samplitude (and related hosts like music maker or Sequoia)?
It loads, runs but nothing to hear.
Thank you.

Yeah, right.
Antti, could it be it's got something to do with a missing call to processReplacing (), that you only call the other way?

I also posted in this board with a bug where ASynth only produces sound in the left channel in Sonar. Just figured I'd chime in with that, just as an FYI, in case no one saw the other thread. Fantastic filters BTW.

im getting similar slightly out of sync results with a buffer size of 256
