Direct capture of Synth Collection within Raspberry Pi Zero

"Yesterday I tired of having to take a Pi, disconnect my UCA202 on my Mac from my monitors, connect in a DIFFERENT UCA202 just for capture (the other is on top of a high shelf), connect cables from the Pi to the Mac, just to capture a synth performance - too many analog boundaries, too many 44100 Hz DAC clocks that might interfere with each other - all I really want is the exact bytes that the Synth Collection is generating, captured as a wav file. And I had all that stuff already in the synths, I just needed to plumb it in and turn it on. So here is a bit-accurate capture of the Synth Collection, captured live on the Pi as it synthesized it. Brilliant idea, should have implemented it years ago - in fact totally awesomely brilliant for capturing a pristine recording of a performance from a live keyboard rig to sync to video. I suspect Soundcloud is internally turning this into a scungey MP3, but what I uploaded was absolutely, exactly the bit patterns that the Pi sent to its DAC as it synthesized this. Does it sound any cleaner? Who can tell - but it should."
