F3 will be less complex to implement that sysex
if your not already using program change and cc 0 (bank select) , you might find these fit more naturally to your use case. than cc1/2
no, you will simply need 16 cc’s
e.g.
say they were mapped to 20-36, and sent CC 24 = 12, then this would change track 5 to filter type 12.
note: your midi process could ignore values great than 16 (max filter type)
one thing you should be careful of here, is that the CC mapping is the thing you are going to sequence, so this has to ‘make sense’ and be easy to do in a sequencer. (otherwise, you’ll never actually use it 
)
another thing to consider…
is each rs7000 track on a separate midi channel? (do you want it to be?)
if so then things like that filter type, id use the same cc, but send it on the appropriate tracks midi channel - again, its about ‘ease of use’
which will work?
BomeBox - it sounds like this can do it… although @CreepyPants says its not ‘easy’ its still going to be easier than coding in C
MIDI Solutions Event Processor - theres no documentation, looks like you have to download their app to see if it can do what you need.
axoloti, rk002, arduino, etc etc
these can all do it, but i think all require some coding expertise, some more, some less.
if you have something like raspberry pi/organelle, these could also do it, and be programmed in Pure Data which is pretty straightforward.
If your not into coding, id recommend :
a) find a friend that is …
this is a very quick simple task, and you can work with them to decide which of about you go for (id be tempted with the rk002 )
b) check out the midi solutioins event processor, but I fear probably it wont do what you want, so the bomebox is perhaps the best option.
