This project is hardcore! #OpenSource, #hardware, #firmware and #software. You can buy pre-flashed hardware.

The catch? It's not clear what components to buy or why, and the setup process is so difficult, it's effectively your new hobby.

I expect it'll get better as out gets more popular and more people contribute to the documentation.

„I have this old keyboard. You can have it. It has these digital sounds we were into back then because we were fed up with the 70ties. It needs a new battery.”

After learning that the guy was talking about his old #Ensoniq #ESQ1, I said yes without even looking at it. It was made almost 40 years ago. It has 8bit #wavetable oscillators and analog Curtis filters.

As with old cars with a flat tire, you soon notice that the tire is not big problem at all… somebody had replaced the pcb-mounted battery by one floating around in there, being easier to replace. I ordered a replacement part.

It turned out, that most of the keys didn't work any more. Luckily the keyboard is a very simple construction. So I inhaled a lot of Kontakt60 vapours, and while I was at it removed the nicotine residues from everything using alcohol… until I got a bad headache.

Does anybodyknow if I can upgrade the #firmware of this #synthesizer using the version 3.5 chips available from Ebay? Or does it depend on PCB bord revisions?
