I don't believe Korg has any support for these now.

Which means you need to reflash the software into the third ROM. This means you have corrupted data in the third flash ROM. Someone posted in a yahoo group this tidbit regarding an error 6: Also I'm told that many of the earlier units were set up like this so that you had to have batteries in the external access battery bay to hold memory!Īnother issue you may encounter are ERROR numbers. Here is a link for detailed replacement instructions. Neither appeared.to have ever had a battery installed! Bizarre. Strangely also, I just worked on a couple of these in a row. Send donations to make up for the first time it happened to me and I had to figure out where everything went. Save you a ton of tracing time knowing that :-). Seen this twice now so it's probably fairly common. Anyway this problem will cause the unit not to power up at all. I replaced with bigger NTE378 and it works fine (reverse the leads). You'll measure between Base and collector a forward drop but not base and emitter. Heres what youll see: Board KLM-1032-A (the large board on the right) has the battery right in the middle of it (round, with yellow plastic around it). The mk1 may be immune to this though corrupt data can also exist in a MK1 I see.Īnother common problem appears to be Q1 blowing open. The problem, believe it or not, was corrupt data in my MK2. First the MIDI destruction was happening whenever I sequenced to it. UPDATE! I got back into these and figured out a few things. We plugged it in and it turned on but had no sounds. he is very talented and can play damn near anything. I got it for christmas when i was 12 or 13. Post by demon » Thu 12:28 am Ive had this Korg since somewhere around 1984. At least the II has sysex loading and some of the factory sounds were pretty identical to some I liked. Korg Poly 800 wont turn on after battery replacment. I have to hold the 'most patches lost' record. I was just moving it into my midi setup after playing it for months and getting used to those sounds.gotta love it. This, being right before i saved the arrangement of course. A cyclic runaway repeating midi stream took it down to the same bizarre sound on every patch. Mine had a cool problem when it midi-looped. The machine I have was a lot of bad solder and cleaning issues. The II which I have adds digital delay though in place of BBD ensemble effect. I have not studied the architecture in detail on this one.some day. General Info Links: Vintage Synth ExplorerĨ DCO's with one Korg Filter.so a mix of polyphonic and paraphonic. It's basically just a panel break out for trim pots to give wide control of filter settings.
