A VU-meter is very expensive to have in a Pd-window, unfortunately. In
cubase (and similar DAWs) those things are hardware accelerated (which
would be cool to have in Pd as well, also inside Pd windows).

It's also rather expensive and not so straight forward to implement with
vanilla objects. Probably this could be done much more efficient with an

Hehe. If you think it's worth to work on that, I'm sure, that the author
(Enrique) wouldn't mind to include your changes. I didn't care too much
about it, but I hear what you're saying (this applies probably to most
netpd stuff.... it's [still] punk, you know, [and will probably ever

I partially agree - I prefer to have a visual feedback of what I'm doing
as well - OTOH it's the ears that finally judge the sound.

Yeah, definitely a good general purpose mixer.

I _think_ this all could be done in Pd. Often when people make patches,
they start with the basic stuff and probably stop at some point, when
they don't feel the need any more to add more features. This makes Pd
patches look poor compared to their otherwise available counterparts. I
wouldn't mind having such a good mixer in Pd at all, though. But I also
don't see an urgent need for it. That's only my personal perspective, of

No, not yet. But by removing all the netpd specific stuff and the
dynamic creation stuff, you could make one based on mx.
