[PD] Anybody in Rome?

[David Sabine]

Hello,

I was wondering if anybody on this list is IN or NEAR Rome?

If so, please let me know.  A choreographer in Rome contacted me via my
website with questions about a MIDI controlled 'Intelligent Stage'.

I'd like to help the project, but I'm in Canada.  Hence, the distance might
make the collaboration very difficult - but if there's a PD guru near Rome
then I'll refer the choreographer to you.

Regards,
Dave Sabine

then created a spigot-like object that will cut the signal going to that
[env~] in an attempt to save CPU power so that PD doesn't have to
continually update the VU meters.  Like this:

too high because [env~ 8192] is computing all the time (zero x whatever?
over and over 5 times per second).  Is there some method of actually
'turning-off' the [env~] or perhaps change its windows size to [env~ 131072]
for example when I don't need to see the VU?
