Yamaha PSR-175 keyboard
Alesis io2 audio interface
Shitty speakers connected via line-in on PC
I can basically launch LMMS, Ardour, etc. Even managed to get Rakarrack to play my guitar, although the signal was system audio capture mixed with the FX in Rakarrack, so it sounded like two guitars.
All I want to do is play my keyboard through my PC and use it as a midi controller to record music in LMMS or Ardour. I can't get the keyboard connected to ANYTHING. It's currently connected to my io2 interface. Audio output in QJackCtl is routed to system output (speakers), input is coming from the io2 interface. For the life of me, I can't get the connection working in any synth, keyboard, etc.
I've read through the official Ubuntu Studio audio production guide, as well as the midi setup guide with Ardour, but I still can't get any connections working. Is there any FOOL PROOF, IDIOT PROOF guide to setting this up for me? Do I just not have the right gear? Any help is appreciated, as I'm entirely new to audio production.
