Hello Kassen, thanks for your help! The scripts I used are included into the last miniAudicle (and maybe ChucK itself, I didn't checked) examples folder. You can grab a copy from the ChucK (mirror?) Github repo [1]. I guess I'll be testing the same scripts into another Machine/OS to see what happens also.
