Volca Tube Germoney puts out an astounding number of live synth jams based around his Korg Volca centric set up. Here's a recent long form techno workout. What is really great about their jams is the raw and punchy nature of the synth sounds and drums. Volca Tube Germoney has no fear! Wherever their heart and volcas take them, that's where they go.
Here is the equipment, they list as being used on their videos: korg volca nubass / beat / kick / fm / keys / bass -- korg nts / sq-1 / kaosspad mini -- korg monotron duo / delay -- tascam model 12 -- arturia keystep 37 -- akai mpx8 -- behringer xenyx / bod400 -- harley bentley digital delay / ac true tone
