„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?
