	I can imagine, that the size of the keyboard depends on the basic
	construction. We have different aspects and possible (and reasonable)
	concepts:
	
	1.) extend existing products
	2.) develope a new product
	3.) The user is a piano orientated person
	4.) The user is a machinery/sequencer orientated person
	
	Point 1.) Since I assume, that the keyboard scanning stuff and everything
	will be done in the same microcontroller as for a MIDI-keyboard: Why not
	build an addon card, that enhances the controller with a single
	CV/Gate/Vel-CV output. Assumingly either there is uC power (and bus power)
	free for doing this (but I don't believe this) or it would be a MIDI/CV
	interface, that offers some last/firstnote priority algorithms. This could
	be added easily to each existing wide Doepfer keyboard, or it would be
	simply a combi pack from an existing keyboard and an existing MID/CV
	interface.
	
	
	Point 2.) A new product might use a new uC program. This might include
	functions like hold, portamento, clocked gate, transpose, arpeggiators,
	sequencers,.... the addon functions might come as software extension later
	on. The size of this keyboard might be enough with two octaves only, since
	this fits to 19". It would be less a real performance keyboard than a
	little helper, e.g for testing sounds, triggering events, having a
	sequencer and/or arpeggiator and transposing sequences and something like
	that.
	
	Point 3.) The user wants to play pianolike, wants to have velocity and/or
	aftertouch, wants polyphony. To my humble opinion this person should use a
	standard MIDIkeyboard with an MIDI/CV interface. Perhaps Dieter is willing
	to offer combipackages of an acceptable keyboard and the MCV24 with
	attractive prizes. Definitely products for this target group already exist.
	
	Point 4.) The user wants a lot of triggering and controlling possibilities.
	He is interested in including the keyboard in the sound creation. This
	person is the target group for the keyboard described under point 2.) 
	
	
	So I think, a new keyboard should be a small keyboard and it should by the
	No.2-style.
