RE: [vintagesynthrepair] Strange Poly800 problem..sequencer button..kills memory? Midi..kills memor

2008-01-22 by Scott Nordlund

I used to have a Poly 800 II- as far as I can remember, Poly 800 line had really horrible and buggy midi implementation. It only understands the simplest messages, and some kinds of data that it doesn't understand will crash the CPU and fill the memory with garbage. If possible, try to filter your midi data and test which kinds of messages it can reliably handle (you might start by filtering out everything but note on/off, pitch bend, and mod wheel).

Try to start your sequencer program with Midi cables out of the poly.
It's a well known problem.

Wow how bizarre. Every time I hit the sequencer button it erases all
the patches. Anybody ever seen anything like this? Battery is good.
I dunno. Wish diagrams were a little easier to read on that one. -Bob
