I recently played around with SonicLab’s Fundamental plugin with the Thunder Overlay. It has some decidedly funky mappings for the notes, and it helps to have a custom mapping for the Thunder. There are only 8 sliders needed for controlling the oscillators that respond to the “white” notes A2-A3 (#s 57-69), and notes 21-37 select presets.
I used the remaining “long” keys as simple CC sliders for modulation mapping.
In the example video, I used Logic, since there were some initial hiccups getting it to work with Bitwig. I used Logic’s MIDI learn to map the sliders and hex pads to control modulation and effects.
Here’s a modified Thunder mapping, derived from the Bitwig MPE map for the Thunder. Preset 9 is the one I modified for Fundamental, so load that one up.
