Just a few more thoughts.

I set istarttime to 0 and created 96k 24and 32 bit mono sine wave files.
diskin2 worked perfectly.

OTOH the sndwarp example was very bad.

Creating the table in instr2 on every call seems excessive, but I am
assuming there is bits you have suppressed

If I change the ktimewarp1 value from 1 to 2.7 (rather than 0 to 2.7)
and reduce the gain in the sndwarp from 0.3 to 0.03 I get more or less
what I expect, a 440 tone with artifacts from the granular synthesis.
I suspect you need to do more experimentation with the sndwarp parameters
to get what you want.

Yes, I was briefly isolating the problem. I guess the alternative would be loading soundfiles permanently, but I couldn't do that with all 4000 soundfiles I have on my list. I’m not sure what the middle solution would be. I also use 16 channel inputs, loading each channel into a table for each note. I have noticed there is a polyphony limit when I do that, it often seems to overload memory.

I have been trying to use the time pointer mode, using randomized curves generated with Open Music. But I think I have used the wrong range when itimemode is 0, thank you for that. I’m trying to include all alternatives in one instrument.
