Version 1 is Finished!
I have now finished the code. Tested it and after a few bug fixes, everything works just great. The final software is 930 lines of assembler. You can download it here if you want to.
I also learnt how to use ProTel so I could draw up the final circuit properly. Here’s the result. Notice that I’ve got it down to just one chip now, the little PIC is doing everything. It can directly drive the LED and the MIDI output. I’ve used multiplexing to enable it to drive the 7 segment display and read all the inputs. The PIC’s built in timer keeps everything running accurately, all in all, I’m very pleased with the result.
I threw it into a box and its done! You can see in this photo that I also added a second MIDI output.
I try to download the code but always indicates “Sorry, no posts matched your criteria”
Why ?

Sorry, a few things got broken when I changed service providers. This link is fixed now.
Great! where can I buy one!!!
Well, I have built a few here and there for some people but it was just really a hobby project. I didn’t think anyone still used MIDI anymore.
I do have a few circuit boards left over, I could probably build one up for you. I’d have to work out a price too. Email me at adam@doctort.org and we can talk about it.
