No the audio coming out just sounds like there is one instance of the instrument playing. In the terminal output I can see all my f-tables are being allocated, in the example I gave there are 20 instances called so I see 20 f-tables being allocated, I have tried setting a different offset of the pvs buffer for each instance to read from based on the p5 sent from the PVSBuffer instrument, but still no joy.
