Did you know that Motorola had MT32 compatible sound module back in days? ;) motorola.jpg My little MT32-pi in old TV set-top box project is shaping up nicely. Now I need to fit that rats nest into case and figure out how much cooling Pi 4 in closed case needs. Will went holes drilling be …

Hi, I'm the author of mt32-pi. Sorry about the broken USB; it doesn't get tested as often as GPIO MIDI so unfortunately I missed it! Re: the volume - it should always be 100 when you first boot up. Some game/MIDI song will have lowered it via a SysEx message, I imagine. The volume will be …

My Whiskey brackets arrived today and I'm really happy with them, they look great! @Whiskey, you reminded me I had some Autosol lying around so I hit one of my brackets with the Dremel too and it finishes them off really nicely: https://i.imgur.com/guNE1P7h.jpg (right card is unpolished) Thanks …

That triangle bothered me instantly, and I'd never heard this MIDI before - it's very jarring. It's almost like it's being faded up towards the end of the note. I see what you mean, you're absolutely right - it sounds great with PLAY.EXE: https://drive.google.com/file/d/ …

Good points 😀 I wonder how feasible getting custom brackets laser-cut would be? The PC MIDI clone card I bought from marmes/keropi seemed to have a custom made bracket and it was quite good quality - would be nice if the cost of producing a batch isn't too bad.

It looks like the standoffs/screw posts of the joystick port would keep the bracket attached. Some of the smaller versions of the ESS AudioDrive based cards seem to have this layout and not have the additional mounting screw through the PCB.

Nice work! What a coincidence - I've just done the same fan mod to the same PSU (although mine has been rebadged as "Perfect PS220-SM" - inside it has the Bestec BPS-2004-4U PCB). Maybe the summer weather has made us think about cooling our PCs better. :) I agree - the original fan was SUPER loud ( …
