technical notes.

  • both M8 and S4 connected to mac desktop using usb.
  • then using Loopback, i route audio from M8 to S4 with details:
    • M8 Main Out to S4 Track 4
    • M8 Track 4 (Pads Hypersynth) to S4 Track 2
    • M8 Track 1 (FM Bass Synth) to S4 Track 3
  • S4 Track 1 is playing back sample that i also recorded from M8 via usb-Loopback. more on this, at first i tried to connect directly using usb from M8 to S4. it worked, but there’s audio crackles. i assumed this happen because of the different sample rate. M8 is 44Khz and S4 is 48KHz. so i found a workaround that is working nicely (no crackles) using Loopback as a bridge.

  • M8 also sending midi to S4 to send clock, control Start/Stop,
    • and send midi cc to control Mix FIlter of S4 Track 1 and 2.
    • i did this using Midi Patchbay app, its an open source app. very handy app with for this kind of situation, just want a simple routing without needing to use DAW.
  • then i use ableton just to record, set audio input to S4, audio out to my audio interface for monitoring.

  • its amazing nowadays how you can multitrack record music gear without using audio cables, only 2 usb!
  • and just want to say Loopback is really really nice. simple, but very useful.
