if it is turned on in the host it runs, if it is turned off in the hosts it does not run.

(it does not receive audio when turned off)

I'm more curious about the other way around.

I cannot have 16 spectral EQs running in MSP at the same time - even if no audio is going through them, the processor load jumps way up with them just sitting there. Thus, poly~ or mute~ is necessary.

Does the host do this for me automatically, or do I need to have an on/off parameter within the plugin?

as far as i know...

if it's an effect, processing will be shut off when no audio is received by the plugin - (i think the time before the procissing is stopped can be set with the 'tailsize' message to plugconfig....

if it's an instrument it will always run,- to be ready when you play a note ;))

well my previous post seems to be wrong for some hosts, in logic it's true, so maybe poly~ is a good idea for cubase and others ;)

instruments also should not run when turned off. :)

Arne ... if the 16 effects are in one plug-in you need to use poly~ , if it is 16 different plug-ins the ones which are turned off require 0 CPU cycles.

generally speaking pluggo does not behave differently from other plug-ins; the audio simply does not run when turned off - only messages or midi output are active in a turned-off plug-in when you dont do anything against that in your code.

When using turning an audio subpatch on or off in max I tried mute~ or poly~ or pcontrol but I ran into two problems: clicks (even with pass~), and filters that explode when you turn it back on.

Instead I now build the subpatch to a vst, load it in vst~ and use the bypass message to turn it off. This saves cpu just as the others but doesn't have this nasty behaviour.

btw I didn't do any of this inside another host but max.

In a word yes. You could use plugsync's host features to turn processing within the plugin off if need be [while the sequencer is sitting still] , but it sounds unreliable. Check the leftmost outlet of plugsync~ and the mute~ object. Also theres bypass and mute for the Vst~ object if you're using that.

Hi,

I tried some times ago to create a "CPU gate" thru the use of the mute~ object and idle detection. THough it sometimes was too slow to react (max data rate).

Would it be possible to control mute~ with signal rate ? Or for poly~ to accept signal based disable control ?

Thanks,

Salvator

if poly~ would accept signals for turning signalling on and off, you could only turn it off once.
