#Korg poly 800 battery replacement mod

I want to fix it as much as possible and then plan some enhancements to it, with the help of Doug and other knowledgeable brothers-in-synth-diy-arms. Heaven made it so that after some cleaning and connector-pushing, it's aliiiive! I was quite close to envisioning extracting the filter chips and selling them separately. Desoldering it was a lengthy process, but I had perfected the craft somewhat. Thanks to the other DougT's inspiration about salvaging parts this summer, I practised and managed to repair the broken encoder on an Alesis Micron. First, I need to get a new battery holder and battery there, and maybe fix some of those non-triggering keys.

I am really, really tempted to try and do an External Audio into VCF mod on this synth. I guess the cleaning and brushing gave it the final kick and maybe pushing those connectors too. When I did this, I heard the notes arpeggiating correctly, so I deduced that the synth is working correctly up to the voice + filter board and that perhaps the issue was the next board, i.e. However, the following is something I tried yesterday with all the filters while the Arpeggiator was on, and hence I knew that I would be able to make it work at one point: connect the penultimate pin down on the left to the third pin from the top on the right.

The sounds on the DW-8000 are awesome: lots of superb strings, pads, brasses and clangorous tones too.ĭid you try removing the connectors, cleaning them up and putting them back?Īlso, try a power on while maintaining 5 and 8 and re-send the patches by SysEx.Īpart from cleaning and brushing the board myself last night and pushing the connector back in, I am not too sure what else I could have done to make it work.

I actually also took the battery from the seller as a souvenir and the greenish residue does come from its edge. They are less prone to leakage than the other coin batteries and other non-coin ones, but this one still did.
