Toggle led on a roland f 100 mkii foot controller

Hi,

First of all, you have all MIDI in ports going to all MIDI out ports. Each message type will need to be directed to a different port. In the attached examples, because the preset is set for input of FC-100 and output of application, the CC message will only go to the application.

In the second translator, I overrode the destination to send the Sys-EX message by to the FC100

Now the second issue is that the FC-100 requires a bit map for devices so I had to bitmap ga to the 8 pedals. The first 4 bits are mapped to pedals 1-4 and the Sys-Ex address is 0x24. The second 4 bits are mapped to pedals 5-8 and the Sys-EX address is 0x25. I have to use several rules for evaluation and doing the correct mapping. Instead of toggling the entire value of ga, I only toggle the proper bit which is done in translator 0.0

We then evaluate the incoming message in translator 0.1 to determine which address to send to and we send information on all 4 bits for that address.

For bit mapping reference, you can look at this post.

Give it a try. Again, I have no way to test (except on paper).
