I got it working using another (free) program called "touchdesigner", translating the midi coming from the axoloti to OSC for OSC/PILOT.
This is fun!
I've made a combo of patches, one in OSC/PILOT and one in axoloti, with which I can draw a fft-spectrum or randomise it, do some spectrum-adjustment calculations, a X/Y/Z morph-recorder through the 8 available waveforms (with record position being fed back through the midi2OSC mapper of touchdesigner) and play this as an 8-voice polyphonic oscillator (with polyphonic X/Y/Z morph following the recorded motion) using a tonnetz keyboard I made in the OSC/PILOT patch. So now I can quickly modify everything from my screen using multiple fingers, play around with the spectra, play multiple notes and parameter-bends/changes at the same time
Now gonna try to build a performance midi-recorder in axoloti, so I can record my keyboard presses and also return this as visual feedback
