waveform

hi,

I have a very simple patch on which I'm encountering some issues with the waveform, and really couldn't figure out what's going wrong with it.

1. the waveform doesn't download the sample properly (it shrinks the sample very often).

2. Also I'd like to have this patch as 3 Bpatchers in a main one. When I create the 3 Bpatchers, everything is downloading properly and acting separately (I added #1 and different arguments in the inspector window), but the waveform is not working independently (I don't get 3 separate ones).

here is for overview :

if anyone knows what's going wrong and could help, I would much appreciate.
many thanks in advance,

best,

Coralie
