Bc2000 (for the BCF2000 & BCR2000)

Hi

> I am looking to purchase a BCR2000 and polyevolver rack (which I found for a great deal).  But want control.  Thus I found some of the evolver patches here which look great!

> But, I was wondering how the LEDs interact with say an evolver patch on the BCR2000.  If I switch or load a new preset on the evolver, do the LED's change to the new evolver preset settings or do the LED lights become 'dead' or return to zero value.

The way feedback (resetting the value of the encoder/button/fader and therefore the LEDs) works is, it only works with Midi CC messages.
So if your synth outputs all its values as CC messages instead of sysex then it would work. 

In other words, in most cases you can't get it to do what you want without having a PC in between the synth and the BC. And even then you would have to write  a program to convert CC to sysex messages to send to the synth and sysex to CC to send to the BC.

The BC has no knowledge of the state of the synth, so it just outputs the next value and the synth parameter will jump to that value.


When you program the BC you can set the default value, that is, the value that the control has when you power it on. After you move the control and change the value the BC remembers the new value until you turn it off, even if you change presets on the BC.

If you program the BC to output sysex for your synth, you could copy the preset and change the the default values so you would have a different preset on the synth. You can also program the BC to output all the values when you change to that preset. 

So on the BC preset 1 could be "Fat Bass" and output all the sysex messages to the polyevolver and you could vary the synth preset in real time.
BC preset 2 could be "Lead Saw" and when you select it the polyevolver would change with the flood of new sysex values from the BC.

There are 2 problems . One, there are only 32 presets available on the BC. Two, if you were to return to the preset 1 on the BC it wouldn't output all your program defaults, it would reset the polyevolver to the 'tweeked' state it was in before you changed to preset 2.
You would have to turn the BC off and then on again to reset to the default values.

Hope this helps
