Shortly after that milestone the nights closed in and all work ceased. But I did say there would be a video of it all working. Well, I'm pleased to say that this May Day bank holiday weekend the weather has been as sweet and warm as a the sound of an analogue synthesiser. With my usual trepidation I powered up the old monster and was glad to hear it was all working as before. Well, almost. The highest A sharp was pulsing on and off because a transistor had been pushed over and was shorting. And the Violin section only works if the Orchestra section is on, but that's just a bit of a bother with the switch.
Here then is a short bit of unrehearsed and barely thought through keyboard playing. The Yamaha PSS-580 is the MIDI keyboard.
Wow, eh?
Well, I will think of some more interesting things to play on it, but you get the idea. It works!
I also had time to measure the current on the +15V rail. It seems that I will be able to use the existing supply for the MIDI interface too! Hooray! I have another post in the draft folder all about how to have the power supply in a separate unit. Hang on to your hats!
