I've done that MIDI in subcircuit on breadboard and perfboard a number of times and it worked well with my stock of H11 optocoupler chips from Ali express. A midi interface typically needs to have a 1MHz oscillation signal divided by exactly 32 to get to the midi spec's 31,250 bps. Is that what...

I asked @Tashtari directly on discord and this was the reply: Personaly, I'm all for an exclusive MIDI interface as a cheap standalone - more people would be after that and it wouldn't force the higher cost of the MacRecorder upon it.

I made a 23 minute video on building it and messing with it (mostly for Studio Session)

how it started: how it's going:

Ah, the confusion from my part stems from demik's profile in 68kmla, I must have seen that since some euro currency price was referred at some point in some post, so I was curious, and I just assumed you, as a collaborator, hauled from France as well. My bad.

That's very kind of you, but we're based in Canada and the US and according to your profile, you're in France. I've already committed to get one from AliExpress.

Don't worry, I don't think you're being negative at all. Getting a project under multiple constraints is always a challenge and part of the fun. I'm well aware that I can bring modern day audacity recorded wav files and bring them to a system 7 mac first, run "Brian's sound tool" and convert...

I've been able to assemble a group buy of 4 boards being accounted for, so that part about ewaste is solved. The other aspect that isn't solved is the feeling that buying a $30 PIC kit3 that's used for this and never again makes me sit uneasy, but if it's the cost of doing business, then so be...

I don't see the PIC in this supported list unfortunately: http://www.xgecu.com/MiniPro/TL866II_List.txt however (video example at correct time stamp): but no telling if this particular one used in the project is supported.

Another question, the front panel comes up at around $25 in JLCPCB but it has strangely selected a "plugged" setting for the VIAs. My understanding is that those panels are nonfunctional and are just there to provide space for the plugs and knob (a great strategy that was also used in the...

found it in the releases page! https://github.com/lampmerchant/tashrecorder/releases

that's great! I have a TL866 programmer so I'm gonna be looking out for a tutorial on one of these. I guess the workflow would still be to install MPLAB 5.35 to get the .hex and use that in the TL866 software (which I've used in the past for redoing a set of Mac Plus ROMs) Would you be open to...

Looks very fun to build and own. I would have loved to use this to make my own sound effects in World Builder rather than rely on poor shareware disks filled with sound clips that were more or less relevant. I'm not clear one the PIC12F1501 programming. Does it involve a special hardware...

Update: I'm working on a video. Short story: the GND pins must *not* be connected together. it was drowning the signal when all connectors were present. pin2 of the DIN5 sockets are only tied to the midi cables' shielding, nothing else. Not between each other. Details in there...

The solution was suggested to me from various people from 68kmla and mastodon, I thank them all. Here's a quick test of a major scale with every note played with a delay of 1s between each: this was the magic ingredient that I was missing to finally force the serial port to behave at 31250...

a bit late but here's my github repo with the python code after a few iterations: https://github.com/Mu0n/PythonMidiPlayer It can deal with: Type 0 (single track) and type 1 (multi-track) .mid files siphon off the relevant MIDI commands for playback (note on, note off, pressure, etc) parse...

I walked back my true and tested method of shove-Dupont-M-wire-end-into-J12-socket for my SE/30 and got myself a J12 passthrough from jcm-1.com hosted by Joe, designed by @Ron's Computer Videos. https://jcm-1.com/product/j12-passthrough-for-se-se-3/ The IDC connector at the side of it is...

I assembled a small breaboard midi-in circuit, powered by a bench supply providing 5V, according to this well known circuit: which looks like this (I had optoisolator H11 chips from previous projects) and just to prove it works, I plugged my pocketmac midi out cable to this breadboard...
