I'd like to connect my old Korg c-15s digital piano to my Toshiba Satellite laptop using a plug and play cable (midi > usb). I have never done this before, tried a few tutorials but couldn't seem to succeed. I'm not interested in using the piano as a midi controller or anything fancy, just record it using Audacity or some other similar software.

Here some information.

System Devuan Chimaera kernel 5.10.0-21-amd64 alsa and alsa-utils installed qjackctl installed audacity installed This is a screenshot of what appears on qjackctl connections where I assume 0:CH345 MIDI 1 is the piano interface.

  • As far as visible from your lsusb, the keyboard can only be used as midi controller! If you record something with that, you need synthesizer software that takes these midi events and makes tones from them. Commented May 5, 2023 at 5:38
  • Could you suggest some such software that's easy to use? Commented May 5, 2023 at 6:35
  • Rosegarden seems to be suitable. Check your distribution for a package. Commented May 5, 2023 at 8:01
  • I'm really not a musician, so I have no clue what "easy" means, but I think the standard is musescore (which I think is a fair bit less "dusty" than rosegarden). Commented May 5, 2023 at 13:17
  • I do have musescore3 installed.I tried to configure it to use the midi input with qjackctl but it doesn't seem to work. Commented May 5, 2023 at 18:31
