This rackspace is designed to use two keyboards or one split keyboard (for which is set up now) to vary between two sounds (totals 4 plugins involved) for each LOWER and UPPER keys.
Which one of the two plugins is enabled can be set with an “ACTIVE” pad.
So all in all it just enables you to set one, two or no sound for each keyrange/keyboard, and the unused plugins will be bypassed to save resources.
The clue is that i not only used MIDI-filters to avoid stuck notes because of “missing” NOTE-OFFs, but i also used the Envelope Follower (new in V5) to detect if the outgoing sound of a plugin is really silent (long dealys or reverbs) before switching it to bypass, so a sound can ring out, or can be hold while you can switch to the other sound which of course can instantly be played (and the “old” sound still also plays). That guarantees smooth transitions between sound switching, no surprising “audio zombies” which start to play again when the plugin is revoked from bypass (happens with a lot of plugins!), but yet there are no more plugins active if not used.
BTW: This also works when you switch variations.
I had to use some scripting to make this possible, but it’s not that much.
For each Envelope Follower there is a “Sense” LED which indicates if there is sound detected or not, and also a “Threshold” knob to adjust the loudness of what is detected as “silence”.
Low values will cause the Enveope Follower to be very sensitive, which means the audio might get really soft and silent before detected as “OFF” (good for long reverbs), but this keeps the regarding plugin to stay active for all that time, and active plugins consume resources.
So, that’s something you’d have to try for your own sounds.
I have locked all the widgets from user interaction (mouse) which are handled by the script, so you can’t manually cause unwanted situations which would lead to unpredictable results.
Just exchange the plugins and MIDI blocks with your own ones!
OK… many words, here are some pics:
For the nosy ones, here’s the script which works behind the curtains:
var
