And yes, eight outputs is pretty nice already, I've implemented 15 in software ... but then again in my code it works a bit different .. guess I should try this bounded version as well (with the four bounds treatment options).

I believe a pi-zero has enough pins to do this. Or Arduino. _________________ FPGA, dsPIC and Fatman Synth Stuff

I'm looking forward to seeing your pcb for this
I still think it's a problem best solved in digital-land. |

Oh .. an analog implementation would be cool too |

If I built it on perf I'd probably spread the circuit over 3 PCB's. 2 of them will have 4 muxes and a latch and 1 PCB with the rest.
Hmm, with the AND gates added to the boards with the muxes you get a system that could be easily expanded to any number of cells.
It would probably be more suitable for point to point wiring although I'm not a big fan of doing that, but that's partly because I don't
really have suitable wires for it. I bet synaesthesia could probably fit it on a pretty small board. It's almost tempting to just solder the
chips on a PCB with some headers connected to all the pins and then use dupont wires to connect everything together. Like a reverse
breadboard. _________________ "My perf, it's full of holes!"

I might test it with a PIC I actually have a nice extension with 32 inputs and 32 outputs that I can use for it.
heres a photo:
I have a small controller for it with a PIC but I'm not sure where that is at the moment. Actually a larger controller with
an LCD screen, a bunch of toggle switches and buttons and maybe pots could be usefull. I could add more in/outs to also
interface it with my lunetta stuff. I do have an Arduino which I haven't started with but that might be even more suitable
than a PIC for something like this as it would be easier to update the code. _________________ "My perf, it's full of holes!"

I've been using the small Altera MaxII CPLDs to build bigger things.
Using the block schematic design in Quartus; frowned on in the FPGA community.
The Chinese development boards are sub $10 on ebay.Search "CPLD EPM240 or EPM570"
Vidme took down the videos I posted in " A heretical approach to Lunetta design" but the block diagram file is still there at the end.
I've since dropped all the lines when I found they weren't necessary

where ordinary people have a bloodstream - Mr. Phobos must have a bus-system installed
maybe from the god of binarys in order to cure us poor humans from the analog sickness
