@MazHoot So I fired this up in BlastEm and was quite pleased with the voice edit view, even though it uses pure register values instead of MIDI like I'm used to. If I could get that with genMDM it would be next level in a mixed workflow like mine.
Just dreaming is all, don't want to distract from a perfectly good project 
Now if we can just combine this with GenMDM...
If there's enough interest, I wonder if we could campaign little-scale and/or Catskull to either develop an update to the genMDM firmware, or open source it so someone else can pick it up?
Hey MazHoot thanks for the response. I managed to find the v101 firmware doc through little-scale's blog but unfortunately it wasn't much help. So I just decided to experiment on my own rig.
I assigned a knob on my MIDI controller to one of the SSG-EG controllers (CC 90 for OP1) and found some interesting results in what the data values actually do with the SSG-EG programming:
0-31: effectively "off"
32-35: pattern 1
36-39: pattern 2
40-43: pattern 3
44-47: pattern 4
48-51: pattern 5
52-55: pattern 6
56-59: pattern 7
60-63: pattern 8
...now add 64 to all of these (yes, ALL) and the whole thing repeats.
Odd, but I'm guessing it has something to do with how the SSG-EG register has an enable bit in addition to values representing the patterns. No matter this was a useful exercise in figuring out what data values to send on that controller.
I've also encountered some odd bugs but it seems they don't always manifest. My main gripe right now is that writing to RAM presets does not retain. I'll need some kind of patch storage for my project so I don't have to rely on the Max 4 Live devices.
Hello,
I am working on a little DIWhy project to build a controller for GenMDM similar to what Look Mum No Computer did here with his Megadrive Synth. For testing and prototyping I have successfully managed to get MIDI signals to the genMDM with the Max 4 Live device provided by Little-scale, and some custom mappings on my Launchkey37. And yes I played notes and got sound on all 10 channels. Didn't try CH3 special mode yet...
Anyway...
The SSG-EG parameters for genMDM seems to have some inconsistent documentation around it. In the MIDI mapping doc, the data range is 16. In the M4L device, the values range from 0-31. From 3 different software-based YM2612 tools I've played with, there are only 8 SSG patterns, and OFF. Deflemask did their own thing and added an Enable tick box with a 0-7 data slider.
It's going to be very tricky to manually figure out when each SSG pattern kicks in, so I'm wondering if anyone's managed to figure out the data values? Worst case I can... try.
Cheers!
Confirming, same issue and resolution for me. Running a US Genesis model 2 revision VA1.8
I'm curious if this is an issue with particular MD/Genesis models? I saw a comment on little-scales youtube channel about this situation, but it doesn't seem to effect all users.
Hello everyone!
I was recently inspired by "Look Mum No Computer"s Megadrive Synth and thought "hey that looks like a fun way to pass the time during lockdown, lets give it a shot". I discovered this forum through searching for design inspiration and also troubleshooting tips for the GenMDM as mine is behaving a little oddly and I'm not sure where to start troubleshooting. Anyway, I'll be exploring thoroughly and checking out as many other projects and recordings as this site can provide. Cheers!
