Music to my Ears

“What’s is this?” I risked putting my wife to sleep, and explained how it replicates the expensive synth units of the ’80s and for just double digits today, how I could replicate what would have cost $1400 in 2023 dollars (“girl math” would surely win her over), and showed her a before and after of Space Quest and Dune... “Oh. Okay.”
She didn’t care. No one cares. But if you’ve sat through hours of soundblaster, this baby is revelatory. If you made it this far and you’re debating it, it’s a pittance compared to the cost of an original unit, and a breeze to set up, and a much more pleasing experience than sticking with ear-splitting stock software.

With the kit’s variety of screws, I was able to use a spare Pi3b+ with the kit. With the auto installer script from the GitHub, I was able to format a spare micro sd, install 99% of what I needed, copy wifi settings, remove voltage warnings… all but the roms in about 30 seconds, no joke. Win + F12 in AO486 showed it was recognized after popping it in the pi/mt32, and I was off to the midi races. X68K hammered out those sweet Castlevania synth tunes. Now I’m playing PC games like a 90s rich kid! For me, this is the flip-side of the coin. The MT32-Pi kit is to Computer cores, what Reflex/SNAX is to Console. Can’t imagine not having it, now.

Haven’t received it yet

But hope it’s great !


Works great...once I realized I had the wrong DIP settings for the Digital IO board. The switches on the DE10-Nano are in reverse order with SW3 being on the left and SW0 on the right.

Amazing stuff

Its just amazing hearing how good dos games can sound with the mt32. I was hesitant at first, but Im glad I tried it out.
