Based on the circuit diagrams from the videos, some discussions on here and on Reddit, and a bit of experimentation, I came up with this:<br>

<br>
It downsamples to 24kHz pretty stupidly, so it only "plays properly" for 48kHz samples.<br>
<br>
If I could find a working MIDIFex ROM I expect it could be cooked into a format suitable for this, too.<br>
