I haven't done the work or checked the pins, but this might be possible.

  1. Get one of these tiny tea5767 FM Tuner modules.
  2. Mount it on the back of the Teensy (on stackable headers) on a little PCB
  3. Connect the data lines to spare Teensy digital pins, connect the audio output to a Teensy analog input
  4. Route that analog input through to the Radio Music outputs
  5. Rewrite the firmware so that Bank 1 is live radio, tuned with the top pot (not sure what 2nd pot might)
  6. You'd need some kind of antenna solution

I'm told that the FM chip in both the Teenage Engineering OP-1 and the Buchla 272e is the Silicon Labs Si4702 http://uk.mouser.com/ProductDetail/Silicon-Labs/Si4702-C19-GM/?qs=JiL6vA75y8N8IR2LBUYDsA%3D%3D

£8 per unit, but those are a pretty good heritage, and it is still in production.
