I’m a chap of many interests, most of which are not going to get a mention here, but I’ve been buying and playing synths for over 20 years, and dabbling with DIY electronics for a little longer. When things started to go wrong with some of the vintage pieces I’d bought, I took the plunge and started to learn how to repair them. At first this was mostly stuff like crackling sliders or dodgy buttons, but since then I’ve managed to bring dead old keyboards and rack mounts back to life, have made one or two modifications to things, and have built my own equipment too – some from kits, some my own concoctions and adaptations.

All the information in these blog posts will be either available elsewhere on the internet (service notes, for example, which I will only link to if they are to be found easily for free, and not if they are of current commercial interest) or will be firmly based in my own experiments and experiences of working with specific items of music technology.

I hope this blog will be useful for those who wish to repair these same, or similar, pieces of equipment, or wish to learn something of their technical nature. I also hope it will be interesting, but I can’t guarantee you’ll stay awake through the whole thing…

    Hello, saw you mention something about adjusting the gate for a CS5?
    Ive got a CS15 that I cant get a midimplant working on because even though the gate puts out +15 and 0V, the input to the key on still stays at 1.3V at TP19 and 24 when gated. The positive off gate is also lowered by about the same amount (to 13.6V)
    Theres positive voltage coming in there, would it help increasing the resistance?

    What did you do with the CS5?

    Best Regards

    Hello! I was watching this video on having 2 oscillators and was wondering if you knew how I could then feed them out to my Mother-32? it seems to steal the patch points to make this happen but I’m imagining there’s a simple way to create an out from the breadboard?
    here’s a link to the video I’m referencing…
