NOTE:

Due to the lack of time, development (on my side) has been stopped (still feel free to submit PRs ;)). Meanwhile, for a working and actively developed Overbridge<->JACK bridge, please see: https://github.com/dagargo/overwitch

snd-digitakt

ALSA driver for the Elektron Digitakt

Build as an installable kernel module on a running system

The driver can now be built on your system without pulling an entire kernel tree. However, the build requires two files from the kernel tree that are not normally exported into the kernel headers package. The build will attempt to grab them from github. If that doesn't work right, you may need to find them yourself. See the Makefile.

Build

cd sound/usb/misc
make

At this point you could simply manually install the module into your kernel:

insmod snd-digitakt.ko

But, you probably want to install it...

Install

sudo make install

Load it

sudo modprobe snd-digitakt

Run it

1. Connect your Digitakt
2. Put it in Overbridge mode
   • Settings (gear button) > System > USB Config
   • Select Overbridge, press Yes
   • Select Int to Main, set to Off

Now you should be able to see the device in ALSA's utitlies:

aplay -l
arecord -l

If you want to use Jack with it, try something like this:

/usr/bin/jackd -R -P 75 -d alsa -d hw:Digitakt -r 48000 -n 2 -p 256 -s &

Test with SuperCollider

Run sclang, then type the following to it:

s.options.numInputBusChannels = 12
s.boot
{ SoundIn.ar([0, 1]_; }.play   // plays master bus out to Digitakt's outs
CmdPeriod.run                  // stop that
{ SoundIn.ar([2, 3]_; }.play   // plays tracks 1 and 2 to Digitakt's outs
CmdPeriod.run                  // stop that
{ SoundIn.ar([10, 11]_; }.play // plays Digitakt's ins to Digitakt's outs 
CmdPeriod.run                  // stop that
