CMOS 4094, 4015 4020, 4024, 40106 clocks, several 4017's, two R/2R ladders, two XOR gates - all except the 4017 dividers are wired for power and pins to the panel.

That's dope as hell! I was looking for some drum voices and someone suggested the Quad Bass, but it seemed above my build skills. I opted for the much simpler PAIA kit. Looking forward to hearing more from you creation. Nice work!

Heres a clip of some beats - I moved a couple jumpers in between takes and changed some clock speeds - but for the most part very few changes make for huge variations.
I'm very pleased with what it can do.

In the vid I didn't mess with drum voices very much - so it does not show off the capabilities of the Bass++ very well.

Luka - by Lunetta stuff I gues I was refering to the CMOS circuits I used being almost identical to how I used them in my Lunetta. There are no Lunetta type noise makers - only counters, dividers etc.

After a few hours with the machine I'd add more simple logic next time. The XOR's are amazing - I'd like more of those, AND's and such. I'd also add another CGS Pulse divider and another 4094 shift register.

Anyway - I like how it turned out. :)

Great work. The panel looks really good. I've got an MPS sitting on the workbench, but might have to grab one of those as well.
