I put this question to the developer of Fundamental, and he suggested I post it here, especially since a collaboration between SonicLab and Sensel is upcoming:
How do you change the MPE range so an octave plays correctly on the Morph? I am using the Sensel Morph but the basic scales do not match the octave spread/bend of the Morph (even after adjusting the pitch bend range on Fundamental).
Certain MIDI keys are hardwired to Fundamental Voices. See them on Page19 of the manual. If you want to assign midi frequencies to each voice, just hover your mouse on a Coarse freq tuner dial of a voice and press the relevant midi key.
Sorry, I don’t have yet the Sensel Controller, but you can forward the question to Sensel directly as they have Fundamental and soon we will announce a collaboration.
