Question about FR-1b extra button rows MIDI

[KillTheAlarm]

See the highlighted button rows. As you may know, green rows play exactly the same notes as the red rows. They transmit the same MIDI data too.

Is there any way to make red row transmit MIDI data that would be different from data transmitted by green row?

 

[Ventura]

since the midi data is also transmitted/used internally, if you somehow
managed to re-program them you would be changing the notes
they play, period.. in or out

to re-map the entire bass or treble is theoretically possible, i do
not know if Roland made that available or if it would need to
be hacked.

As far as I know, for this model there is no external Roland software available

I may have an idea - to put those rows on a different MIDI channel. Any idea how to hack it for that? Where do I get started about hacking the Roland?

 

[Ventura]

all the buttons would still first need re-mapped so that
they did not share any address' with the green row..

it's not like a piano keyboard that you can easily zone and have
separate channels etc.
(they have 88 unique address's to start with, no duplications)

The buttons use rubber strips with carbon element as contacts. If you turn those strips upside down (looks almost the same except for some tiny alignment holes), velocity detection goes out the window. You'll be able to distinguish those buttons by always producing a fixed velocity.

That is, of course, a hardware hack.
