Maybe somebody else here has experienced this?

I send CC messages to my JUNO 106 and Korg DW-6000.
All 'slider' CC's (such as 33 filter cutoff) works fine.

However when I send 'push button' CC's like 66 (OSC waveform) there is no response.
The CC always resets to the manual setting on the PE.
This is regardless if I am sending a CC, or set it manually on the synth itself - certain CC's seems to always default to manual setting on the PE.

Maybe I am doing something wrong or it could be some bug?
Everything else works.
