I use this, and it works perfect after you change out the resistors (read the reviews). It requires no power and is a very clean signal. https://www.amazon.com/gp/product/B07Y2RYHFF Edit: It looks like it comes with the 1K resistors now, so no need to change them out. I almost bought that one, probably would have had I noticed the 1K resister note...

I have a real MT-32 and I ordered the Roland um-one for use with the Mister and AO486 core. I was wondering what is the best way to mix the audio of the two sources into the HDMI signal (if possible) for my display or to a single 1/8 inch stereo output (not as desirable but an acceptable alternative).

Thanks,
