Digitakt MIDI loop back with Supercollider

Elektron Gear Digitakt
#1

I made a SC script for Digitakt. I am only a newbie on SC, so the method I used on the script might not be the best way, but I think this could be useful for someone.
Let’s talk about my setup:

  1. Macbook
  2. Digitakt
  3. Korg Nano Control 2
  4. Supercollider

The goal of this script:

  1. Block the CC 120 to avoid freezing
  2. Loop back all CC (except CC 120)
  3. Nano Control 2 as a mixer, selector of No filter/LPF/HPF, and Filter cutoff

Here’s the script:

Let me know your thoughts and feel free to give me idea to improve. Thanks!

Isn’t this solved by 1.20A firmware?

#3

it said-
Prevented MIDI feedback problems that could occur when pressing [STOP] twice.
but no, at least to my device.

#4

I meant since 1.20 the DT doesn’t freeze with stop/stop and midi loopback so imho you don’t need this part of the script.

Just tested, no freeze with stop/stop + loopback

#5

Not sure why it still occurs to my device, maybe I use USB MIDI?

#6

This is extremely useful, I did something almost identical. SuperCollider is way cooler, but I highly recommend python for midi programming. It’s just so… easy:

#!/usr/local/bin/python3.7

import mido

out_port = mido.open_output('Elektron Digitakt Digitakt out 1')
in_port  = mido.open_input('Elektron Digitakt Digitakt in 1')

for msg in in_port:
  if msg.type != 'clock':
    out_port.send(msg)
    print(msg)

I’d try with a midi cable only to compare.
So with USB it freezes systematically with 2xstop if you don’t filter CC120?

#8

things can freeze for multiple reasons.

#9

Yes, but apparently CC120 was the main (only?) reason with midi cable loopback and 2xstop. Weird if it hasn’t been solved with USB.

#10

Thanks, it looks great!

SC might not be a good option for MIDI stuffs, but I think it’s good for multichannel signal processing, a good pair with Digitakt (Core Audio) .

For those on iOS, Mozaic by brambos is very useful for writing customised Midi channel routing processors. Dead easy to code too with a number of examples posted on patchstorage.
