Like you, I'm a bit busy because I'm working on a video demo too !
But it will be here soon. I've used a Teensy 3.2 with mpr121 touch capacitiv, to make the sensitiv keyboard and extend the numbers of analog & digital input of the axoloti-core. I think you did the same with the doepfer interface isn't it ?
I'm really exited to see how yours sounds. Exactly like you, the hardest part for me was the patch himself. took me around two months. Many nights to understand new things. I had the Buchla easel VST from Arturia to compare the fonctionality and the sounds of my patch. And I've putted some new things that the original easel don't have. Like an LFO sine or random can be set to the internal sequencer for the clock, or on the pitch of each oscillator. Hard sync possibility for the modulation oscillator with the complex oscillator etc...
Do you think you'll share your patch to the community ? I'm thinking about making a final object of mine for the patcher allows user to test it.
So I'm waiting for your demo. So nice that we did something really similar exactly on the same time ! haha
