That pic is from another planet! How the heck do you actually play it?
Does it correspond to any known instrument (like an accordion… the button-type, obviously, not the piano accordion)? I also have to ask why you didn’t want a simple “regular” keyboard?
Yes, of course the pitchbend ribbon is the reason I bought the ExpressionMate in the first place, but it has proved valuable for converting certain MIDI data too, as well as providing inputs for an extra footswitch and continuous controller pedal. In fact, most of my presets are for customizing what the footswitch and CC# pedal transmit (for example, in the preset that I use most often, I have the footswitch set to “toggle” , and use that as a switch for the speed of the Leslie effect in my software Hammond organs. I also use SW1 and SW2 to transmit “one shot” MIDI CC# messages (e.g. to start/stop the internal sequencer in Sylus RMX)
You asked “Could you also please explain in which way the transmission of all those component keyboards on MIDI channel #1 is a handicap in practice” Very interesting question that made me re-thing my midi routing. In a basic setup you will not need to set each set of 49 keys to a specific midi channel.
Note that playing chords on the Maxi is difficult. If chords are desired use a chord VSTi.
The Maxi key range is #36 to #83. It has no black keys so as is it sounds terrible if the keys are not mapped. They need to be mapped and for that I have a custom made key and channel mapper I call Kmap. This mapper only works inside energyXt and Bidule. I use the Maxi to experiment and here I also have developed a few odd key maps.
I need a way to distinguish each 49 set from the other 5 in a set up using EnergyXT and Bidule.
Is each Maxi key range fixed at #36-#83? If there is any way to transpose them before they enter Cubase, you could then use the Input Transformer to channelize according to note range (well, obviously you could only have a max of 128 notes coming in )
You said ” I have often wished there were several such “mergers” available in Cubase, not just the one (badly labeled) “All MIDI Inputs”)” I agree with you so I do this in the “Input Routing” inside energyXT or Bidule with modules and routing.
At one time used Midi-Ox and another similar program but later found out that I can do all that inside of Cubase and it will save the settings. I have used the Input Transformer to assign channels to each “MidiSport 8x8 In 1” (1 to 6). Unfortunately mapping of keys here is probably impossible.
As regards mapping, you could use the Chorder MIDI plugin in Cubase… remember, you don’t have to assign each incoming note to a chord… you could simply assign it to a different outgoing note ).
But do be aware that, unlike the Input Transformer, this modifies the MIDI data on the output of the MIDI track (although you wouldn’t actually notice the difference if simply playing live, but, when recording, it is the unmodified data that gets recorded).
