Bc2000 (for the BCF2000 & BCR2000)

Hi Alan,

> I'm afraid to say this is the same manual as mine. I fear that this is the limit of this machine's sysex abilities - it is rather ancient - and I don't think it's the kind of thing that editing software was ever developed for.

I thought this might be the case.
There are some ancient machines that to change one parameter you have to send a whole preset.

Unfortunately I couldn't find a break down of the preset bulk dump so I can't do that either. If you can find the details this might be an option.


> Is there a way in which the TR-626 (or any other drum machine for that matter) can be used to simply generate a midi trigger and tempo 

Yes, from the Midi spec it shows that the 626 will put out Midi clock

>and the BCR is just used to control the sequencer specific messages in relation to the sysex of whatever synth is being sequenced?

Now, if there is a way of allowing a midi signal from a drum machine to trigger an arbitrary midi note event from the K3m, the note value of which is determined by an encoder of the BCR, then there might still be a way of making this work. Or am I just making this all up from my position of relative ignorance?

Hopeful but not ignorant, I think.

The BC will only send out data when you do something physical to it, except in one case (as far as I know)

You can attach a Midi message to each of the 32 presets and when the preset is selected the message is output.
As far as I know when you change a preset remotely (PC message send to the BC) this message will be output. PC message not Note message so you are out of luck I think.

What you need is a Midi map that you can change in real time.
Notes coming in from the 626 are mapped to other notes and are then sent out.
Very easy to do on a PC (Mac OS9 was the last Mac OS I wrote for.) and you could use the BC to change the map.

I think Bomes Miditranslater might do the job.
Here is the app for the Mac Os10

You could build some hardware. It would be fairly straight forward to implement it in an 8bit micro-controller. 

As far as the BC by it self I think you are out of luck.

All the best
