All of the tracks in the latest YouTube videos with the Circuit Tracks jams have been uploaded to Bandcamp and you can pay what you want for it.
There are seven tracks and the only difference to the versions on YouTube is that the tracks have been mastered using Ozone by Izotope and cropped a little.
The tracks were all recorded live in stereo to the Tascam DR-40x and created very quickly just using the built-in sequencer on the Circuit Tracks with the built-in synthesizers alongside the Korg Volca Sample, NTS-1 and the Axoloti making it a very portable setup.
If you missed it here is the latest video pairing the Circuit Tracks with the Axoloti board.
