Bc2000 (for the BCF2000 & BCR2000)

Hi, I started to write a reply suggesting that you find a way to control the DR880 kit instrument levels via MIDI (p103 of the DR880 manual).  As far as I know, there is no way to use the BCR as a MIDI message filter.  But what you really need is to control the volume of individual voices in your hardware sound module - so the MIDI note messages still get through, they just don't sound.  What is the hardware expander unit?

This gives a fairly unique sound which I'm very happy with. This works very well if I program full drum song performances into the DR-880, but it doesn't really lend itself very well real-time performance, since the DR-880 generally doesn't allow you to edit patterns while in play mode. I can switch drums patterns in real-time – which is great, but I would love to be able to select a drum pattern on the DR-880 and just let it run, then have the ability to mute any choice of drum `notes' in real-time somehow, eg. while the drum pattern is playing I'd like to mute several drum sounds such as the snare(note # 38), and open high-hat(note # 46), and later while still in real-time play mode, un-mute them one after the other in any order, and do the same for any notes within the midi stream.

I couldn't find any GM midi messages to do this. In mode `S-4' the bcr2000 generally sends only performance data created in the bcr2000 – so it could only work if there is a way to allow some of the midi transmission to pass from the midi IN on the bcr2000 to the midi out, i.e. the notes I want played – I couldn't get this to work either.
