I had no luck finding any details on how to precisely calibrate a Korg Odyssey, nor any drawing/schematics/service manuals .... even the docs for the Korg Odyssey Kit has nothing!
I just dug into the main circuit board and, after some trial and error, came up with the following.
Notes:
1. I did not touch the trimmer pots on the power supply/digital board.... I am guessing Midi to CV and DC... maybe another time.... or, if you are brave, please have a go and report back to this thread.
2. Any help in understanding the VCA trimmer would be appreciated. I thought it would be for DC offset or noise balancing but I could not hear/see this. I did hear a sweet spot near centre with a more fizzy sound on each side so I left it there.
3. You can align each filter type (3 types) so that the resonant frequency is the same when flipping between them, and you can have them track a little over an octave nicely.
4. There are no apparent High Freq Lin adjusts so if you drive from an external midi source, very high frequencies can not be reigned in.
ENJOY!!
