I don’t have any experience with the elektron digitak but I do use a Behringer multi-channel audio device with my Zynthian. You need to find out whether Linux supports the elektron digitak. Try this:
- Plug in the elektron digitak to the Zynthian
- From console (ssh or use webconf System->Terminal) type:
aplay -L
This will list all the audio channels recognised for all the audio devices that ALSA (the linux audio device module) recognises.
Also get the output from:
aplay -l
which will list the audio devices. With this info we can see if the elektron digitak is recognised and supported by the Linux kernel and drivers installed on Zynthian and work out what configuration is required to enable it.
