After viewing the projects, i have some questions:
1) Can you use a midibox for adding assignable controllers to a master keyboard who hasn't them?
I have a Roland RD-300SX, which has 2 volume sliders for the upper and lower zones, pitch bend/modulation wheels, midi tx button where you
can send msb, lsb, pc, pan, reverb, chorus, transpose, and select the channels, and 32 setups which can also store the midi tx settings
for the 2 zones.
As you can see this keyboard lacks of controllers. Can a midibox help me to overcome this lack?
2) Could i manage more than 2 expanders/sound modules/other midi stuff with the usb module (max 5x5) of a midibox?
I knew that another limit of cheap stage pianos/master keyboards(like the RD-300SX) has only 1 midi output, so they can control just a single expander.
3) What midibox suits to me and my piano? (I was thinking to one with min 9 max 16 pots and sliders that i had seen time ago on this website but now i can't find it anymore)
