Korg Mono/Poly

[fjcanton2000]

Hi.

First off. Excuse my poor english.

I have and old Mono/poly. I and i want midify.

I have buy a UMR, and it work partially.

the Korg Mono/Poly have 6 select lines and 8 data lines. It have 44 Keys.

When I plug the UMR into the Mono/Poly lines, only works the first 2 octaves. This 2 octaves are the 3 first select lines.

i have checked the wires, solders and sockets.

Its this UMR only 2 octaves range?

Thanks and regards.
