Hi everyone,
since there were quite some questions and discussionsabout how to switch presets with widgets, scriptig, variations… i thought i could try to builld yet another rackspace to achieve these tasks.
The rackspace looks like this:
In the wiring view i used some free plugins (a step sequencer and a synth):
https://www.fullbucket.de/music/sequencair.html
and
I also saved a bunch of GP-Presets, so you’ll have something to play with.
Unzip this packkage into you Documents\Gig Performer\Presets folder
Presets.zip (383.2 KB)
So this is how it works:
You can step through the list of available GP-Presets by either using the +1 or -1 buttons or by turning the knob on the left. When you press the “Select” button on the right, the preset in the highlighted (middle) field will be activated/loaded. The actually active preset name will be shown in the text field on top. That’s pretty it…
You can of course save more presets (i think up to 128) or delete some from the preset-folder - the script should “catch” the changes as soon as you press a button or turn the knob.
Since the knob is in sync with the active preset, it will also be able to store/recall the active preset in a rackspace variation.
Have fun with it:
GP-Preset-Roll-Selector.gig (328.1 KB)
And just for the curious ones, this is the script behind the curtain (maybe some things might be not very elegant or even redundant, but i got somehow lost at a certain point). Well it works… that’s what counts!

indexRange : integer = 2
