Pbind to produce portamento on chords with different freqs

Thank you very much, it works very well… and thanks also for .trace … it’s really very useful to realize what’s going on.
However, it seems that with .trace (c.trace.play), c.pause does not work:
ERROR: Message ‘pause’ not understood.

I will try to study the page on Pfunc that you sent me:

Thanks again :slight_smile:
