Music Synthesis led me into microprocessors in the late 70s. Around the time I built an Elf for synth control (an unrealized dream eclipsed by college then by the C64 then by Midi ) I was buying bits and pieces from PAiA and inspired by their designer John Simonton and contributor Craig Anderton.
At that time they were offering a microprocessor controller add-on, very much like a trainer, for their modular synth rigs and selling bits of software for doing effects and controlling keyboards actions like portamento and the like.
My recollection was that these were 6800 systems just like on the small cardboard boxed Heathkit 6800 trainer. My recollection was off. I just ran across 1978 PAiA catalog to find it was a 6502 variant with membrane keys instead of switches.

The controller is on the cover page and detailed on page 11. The whole catalog is a hoot of hobby electronic music equipment of the era.
A short article on PAiA is here for orientation of folks not familiar with PAiA. https://www.revolvy.com/main/index.php?s=PAiA%20Electronics& item_type=topic
I followed the PAIA equipment closely back then too. But I could never afford to build a complete synthesizer from them. The only thing I have from them still is the little Gnome synthesizer. Instead I would duplicate their patchbay style of modules with my homebrew project using the 76477 sound generator. The name TI gave it was kind of disingenuous because it was a complete synthesizer albeit a very small one. But once I added all of the controls, switches, Leds, etc and grouped them into the various functions, VCO, LFO, VCA, etc, it all fit on a single console panel, it looked just any of those PAIA synths but without the patch cables and no keyboard. Then by the time the end of the 70s came around, and our school bought one of the first synths, ARP Odyssey, I became hooked on them. After countless hours with painting jobs, sweating in a Chinese takeout shop, I bought the 3rd generation ARP Odyssey in 1979, the one with the pressure sensitive pitch pads.the year after that I found a used Roland SH-5, another analog synth, in the back of the music store that I just couldn't pass up, it was a gem - highly sought after this day just like the ARP Odyssey. As the saying goes, that was just the start.....every couple years something else was interesting and had to have. By the mid-80s, having to change jobs and move, I gave them all away to one of my best friends in another band. Dan
