Reverse-Engineering the Alesis MidiVerb I: Where to start?

[@marcmcclain]

Thank you for posting these. Listening to your thought processes out loud is very insightful.

This is amazing! Thank you so much...I repair the odd synth & make clone guitar effects pedals. My all time favorite reverb is this Midiverb....however I've found repairing them is hit and miss. So this is a massive help & just what I was looking for. I used to use a Yamaha DX7 MK1 with the Midiverb back in 2000 when the prices were reasonable...the reverb was incredibly beautiful and organic..very rich and complex without being too polished. I currently have this Midiverb & the Midiflex (Delay Version) Both have problems so hopefully I can trouble shoot them now:)

Yeah for that much logic in the mid-80s it was "make the tracework easy even if the signal names are no longer consistent and connect to pins out of data/address order." Bishop graphics tape was expensive. ;)

I would argue that the address and data bits order is irrelevant - until you want to burn and EEPROM from the outside ;)
