After getting my VSTs to live inside poly~ objects (and enjoying the new lower CPU utilization numbers) I started noticing that parts of my system seemed slower than usual.

In particular, I noticed that loading new plugins into [vst~] objects was taking significantly longer and when I was editing Kontakt windows, operations such as deleting an instrument in a multi would take (literally) a minute or two.

After doing some experiments, it seems to be the case that this problem is due to the poly~ being muted. If I disable the stuff that mutes/unmutes poly~, then everything behaves properly.

I can certainly modify my system to disable the poly muting stuff when I need to load new VSTs or edit them, etc., but I would really appreciate some confirmation that this is problem is in fact related to disabling the [poly~]?

Does it make sense that disabling a poly~ would slow down the loading and/or editing of a [vst~] plugin?

what happens when you open/edit the plug in a vst~in root - while DSP is turned off?

Actually if DSP is turned OFF, then I can edit Kontakt (say) with no delays whatsoever. In fact, I've done that often in the past and so I would have noticed before if the issue was just the DSP system.

OK --- for testing purposes I added a little GUI control that lets me enable/disable the automatic poly~ muting any time I want. (Normally the poly~ muting is toggled automatically based on either incoming MIDI data or the audio signal level falling to zero).

There is no question that (at least for Kontakt 5, the only plugin I have tested so far) both the set up time (in particular the time to load a patch) and the editing responsiveness are significantly reduced when the poly~ objects are NOT muted.

I don't understand why this is the case but it's 100% reproducible on two of my machines. I'm glad to have discovered this. Big relief!

The GUI control? Just a toggle and a couple of LEDs that can be turned on or off interactively or in response to a message.

I was more interested in the using the ~poly with a a sub patch containing ~vst, as in another thread you mentioned issues regarding sending other non-note data to the patch (so I assume CCs).

anyway, perhaps I will have a go first then come back, if I have issues getting it to work.

It does sound like its an exciting performance boost.

ok... time to fire up Max, and continue work on my patch :o)
