Subject: Re: [chromapolaris] Local Off - how?

Hello David,

so I did my gig with the Chroma, but I was experienced, that "Lower Function, Interface, 1 -> Off" does not switchoff the keyboard only, but also the the sliders!  Apparently the sliders are considered as a separate controller.

Relative to the manual reference, LF_interface Controls
1) Whether the main instrument/link instrument/sequencer should receive 'local' keyboard events
2) Whether main instrument/link instrument/sequencer events should go out the Chroma port
3) Whether MIDI In messages go to the main instrument/link instrument/sequencer instrument
4) Whether main instrument/link instrument/sequencer events should go out the MIDI port
Local Off effectively means 'disconnecting the local keyboard' from the local sound generating hardware so:
If you want MIDI messages to be sent, then you want group 4 on.
If you want MIDI messages to be received (to allow events for the local synth to be played), then you want group 3 on.
If you DO NOT want the keyboard to directly 'play' the local synth, then you want group 1 off.
(Unless you have something connected to the Chroma port, you don't care about group 2).
So - if you want Local Off you generally would want:
Lower Function, Interface 1, 2, 3 OFF
Lower Function, Interface 4, 5, 6 OFF
Lower Function, Interface 7, 8, 9 ON
Lower Function, Interface 10, 11, 12 ON

Generally speaking, anything you change in the standard selections can be 'undone' (e.g., you won't end up with an unusable synth).
Note - if you turn local off, then if you want the Polaris' keyboard to 'play' the Polaris, something external will need to echo back the MIDI traffic.
