I built a rackspace for the HaNonB70 plugin using @dhj 's “Rackspace Variation Changing Script” which worked quite well for many presets (my rackspace has 13 presets). I linked the variations to buttons on the panel. The buttons ended up working like radio style buttons. I plan to experiment with this with B3-X when I develop some presets I like. On the HaNonB70 I just used the included presets.
Here’s the script for a 3 preset rackspace:
Organ : PluginBlock
//Called when you switch variations
On Variation(oldVariation : integer, newVariation : integer)
newVariation == 0 do
newVariation == 1 do
newVariation == 2 do
