Patch 11 has a click

when I do:
alles.send(osc=0,wave=alles.PCM,vel=0.3,patch=11)

there's a click in the resulting drum sound.

Are you saying there's no click when vel=0.2 or something? I'm having trouble hearing the difference.

(I want to look at the waveform, but my employer forced me to remove AudioHijack from my desktop, and my oscilloscope is not attached to my Tulip ATM)

Alles has a "write to raw file" parameter I believe

When I do this:

alles.send(osc=0,wave=alles.PCM,vel=0.75,patch=11)

I hear a click when the sample plays. It feels like it's not actually at the very beginning of the sample, but it's very short, so it's difficult to tell. But it's a consistent click that does not seem to be there on purpose, given the pitched drum sound.

Sorry if my first post was unclear -- I don't think the click is velocity dependent. I think it's either in the sample data or the sample data is being read at an offset so there's a discontinuity.

Fixed in ed850fa and 2442329. When amy_headers.py was writing the pcm_samples_*.h files, it normalized the amplitudes to a max of 32768 instead of 32767, so the single instance of +1.0 mapped to -32768, which made a nasty click. Good ears!
