This is a simple Volca Bass modulation trick with MIDI CC message (48 = CUTOFF EG INT) using a LFO menu on Digitakt.
Elektron Digitakt (drum & arp sequence on Microfreak)
Korg Volca Bass
Arturia Microfreak + Zoom MS70CDR (delay & reverb)
Volca Bass + Auto Wah (Zoom 70CDR) + Digitech RP360 (cabinet simulator, distortion) Guitar Effects. Volca Sample for rhythm pattern.
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.
You can download original audio file from soundcloud & feel free to use it.
I did MIDI out mod on Volca Bass and find out some interesting things.
It’s sending out note from the selected sequence (or key press) only. So I can program the sequencer playing different sequence on itself and NTS-1 same time. Yay.
