I forgot to mention couple of other things include CC messages (selecting sample etc). Check the link for the detail. Hope this video will gives you an idea what you can do with new firmware by pajen.
Volca Sample (using firmware by Pajen), Volca Bass (midi out modded) sequencer trigger NTS-1, Behringer multitrack mixer
Random jam with Microfreak, Volca Sample and Drum
Just an idea to make granular / drone sound from the Volca Sample and using as a instrument in Ableton.
I made some melodic sequences using Arturia keystep sequencer (triggering NTS-1) and added bassy stuff with Volca Bass.
Raspberry pi as a usb midi host. Recorded direct from NTS-1 through Behringer usb mixer.
It was not intended but sounds remind me bit of gamelan music so I add some photo taken in Bali, Indonesia many years ago.
