Alex knocked it out of the park with this one. Enjoy!

Not really a bug, just outside the scope of the use case, a mono synth you sequence with a computer, not a poly synth you play by hand.

Ok, thanks again, then I know there is nothing wrong with my genMDM, it's unfortunate though, this should have been an easy bug to fix when development was ongoing.

Yea that's the way it works! this is what things like genajam try to fix

Thanks for the reply! Yes, I know that each channel is monophonic but the way it works on my device is kind of "broken", since I need to release the first key BEFORE pressing a second key for normal operation (otherwise the second note will stop when I release the first key and this is not how monophonic mode usually works). This makes it unsuitable for live playing (unless I use a method for polyphonic playing like genajam or the 2xAA editor).

Example (how it works for me now):
I press the C4 key and the note C4 starts (ok)
I then press the D4 key and note D4 starts and C4 stops (ok)
If I now release the C4 key, note D4 stops (NOT ok, D4 should continue playing until I release the D4 key, this is how it normally works on monophonic synths)

This is normal. each channel is monophonic so you can only play a note at a time per channel.

Hi, I got hold of an old genMDM but I'm having a small problem with it. Basically when I press a key on my MIDI keyboard, a note plays on the Mega Drive, if I then press another key, that note will be played, BUT if I now release the first key, the second note will stop, so there is some problem how MIDI is handled here. Is this normal, or do I have a defective device? I have tried firmware versions 1.02 and 1.03 with the same result.

OK, so the Genajam is amazing! It seems to respond to every single midi channel though, so is going haywire in my studio with all the note data being fired to other kit. Not sure if I missed something in setup. Anyone any ideas?

I couldn't see a Genajam thread, so posted here. Great work Catskull and Jamatar! Cheers.

Amazing. I had seen jamatar working on this, but didn't realise it would become a product to buy! Just purchased. Can't wait!

Keep producing great things Catskull!

Wow, that is a really clever device. Never heard of it before, but looks incredibly fun to pair with GenMDM. Bringing the workflow out of the daw, and closer the hands it always welcomed!

Just wanted to say we've got Jamatar's GENajam make into some nice hardware that's now for sale. His work here is really incredible.

hey great work! keep it coming!

So if anyone is keen, here's version 0.1 of my front end of GenMDM, called Genajam

https://github.com/jamatarmusic/genajam

All you need is an Arduino UNO, micro SD card reader, midi output and a LCD keypad shield. I'm using female to male prototype cables to hook everything up at the moment.

Dump a bunch of TFI files on the root of the SD card and you'll be able to select them per channel It plugs into the MIDI input of the GenMDM and then you can use the USB to send it notes and stuff.

For anyone who's keen! Otherwise, I'll be moving forward with adding full FM parameter controls and working towards a physical prototype in the coming weeks / months.

I'm going to try and design an Arduino based front end for GenMDM. The goal is to have an SD card that you can dump TFI files on that you can scroll through. I'm designing it to have 4 knobs for CC control and an LCD screen and buttons for navigating through the settings / presets.

I also want to add poly support so it will sit between your GenMDM 3.5mm midi input and keyboard / midi device to use it a bit more like a keyboard.

I'll release all the code and schematics once it's all done, give me a couple of months

I built something similar for my lighting rig so I'm feeling pretty confident it can be done fairly easily.
