I want to use my PC and my piano as audio sources but I still want to be able to use my built-in microphone for voice-chat as an example on the pc.

Now, since I have very little knowledge, to prevent wasting alot of money (~ 76€) I'd really appreciate it if you could look over my thoughts and make suggestions and give advices!

My Thoughts:

  1. Buy the M-Audio 2x2 audio interface
  2. Use a 3.5mm (male) to MIDI adapter to connect my PC's output to one of the interface's inputs
  3. Use another 3.5mm (male) to MIDI adapter and a 3.5mm to 6.35mm adapter (I didn't find any 6.35 (male) to MIDI adapters on amazon) to connect my pianos headphone output to the other interface's input
  4. Attach a 3.5mm splitter to my headset
  5. Use a 3.5mm (female) to MIDI adapter to connect my headset's headphone jack with one of the interface's outputs
  6. Directly connect the headset's microphone jack (with an extension cable) to my PC's microphone input

For better visibility I've also sketched everything: setup

Do you think this could work and is the cheapest possible way? Thanks for your help!

  • The M-Audio 2x2 is not an audio interface. It is a MIDI interface only. MIDI is a digital control signal standard. No audio can be transmitted via MIDI. You cannot plug an audio output or input into a MIDI input or output. It won't work at all. You have to go completely back to the drawing board. No part of your current plan will work. You need an audio interface. Your budget may be too small for what you want to do. If you can augment your income somehow, I highly recommend it. Dec 29 '17 at 20:01
  • Phew, thanks! But would it be possible with a simple mixer instead?

  • Well.. yes, but interfacing a mixer with the built-in computer I/O can be very tricky and may not sound great. Ideally a mixer and a decent audio interface will give you all kinds of flexibility. Dec 29 '17 at 20:48
