It seems like I can omit large amounts of the default reaperosc to get this working, but I'm not sure which bit defines each parameter, and I'm still struggling with the syntax. What I'd like to happen is for reaper to send the values for the plugin to specified cc numbers, each time the effect is focused. The acceleration is much slower than I realised on the BCR when in 14bit mode, so it's looking like soft takeover will be too annoying to deal with, and I can't get the relative modes to work properly. So I can only get osc to work when it is connected. Strange, my pc only seems to have an ip address when connected to the internet. ReaperOSC configuration for REAPER's OSC Control Surface. It has not been written or tested with the MIDI/OSC Learn feature, though - it is intended to be used in conjunction with its corresponding. When I can afford to spent some time on this, I may try to iron out some remaining issues and create a BCR-2000 version.

There is probably still some (commented out) code in there not used for the StudioMix but for the BCR-2000. Note that I used a BCR-2000 myself exclusively for testing that script when I wrote it.

The StudioMix script can indeed be quite easily adapted (as it should avoid using the code for motorized faders, and can be optimized by avoiding the use of NRPNs entirely, using 'plain' 14 bit CC pairs instead) and extended (as it doesn't use all the available encoders) for a BCR-2000. However, although they show up in the parameter learn now, they just make the parameter value jump to zero when the knob is turned. I've done some more reading, particularly your studiomix thread, and I've managed to get the bcr talking to reaper and showing up 14bit values in the log. Imho it's also useful as a somewhat abstract example of MIDI to OSC conversion (that is not specific to REAPER or any other product), and as a 'skeleton' for more advanced / specialized scripts (it was also used as a basis for e.g. Right, this script will enable 'learning' bindings at 14-bit resolution, but as such, it is not suitable for feedback, as it simply converts MIDI to 'generic' OSC messages without any reference or match to the address space used by any.

Do you mean that this will convert 14bit values for the learn feature, but won't be suitable for feedback?
