Yeah, it is on my to-buy-when-winning-on-lottery list (despite I am  
not playing lottery) :-) I would be even satisfied with the smaller  
model.

Today I tried to measure the jumping pitch problem with a voltage  
meter in a different, more isolated location and I could not  
reproduce it. Maybe it is coming from an other unit (like a grounding  
issue). I will have to make more tests with my setup to locate the  
source. If the R2M has pitch jumps (in MIDI or CV), I will have to  
return it.

I was in the same state :-) I am sure it is very good as a  
controller, but I still have some concerns to use it as a musical  
instrument, though it should be easier to play than a theremin, which  
I was considering first (but a good one is even more expensive). This  
code from James (with some very minor modification and without the  
cleaning up part) seems to work and feels quite responsive.

s.boot;

MIDIClient.init(2, 2);
MIDIClient.sources.do({ |src, i| MIDIIn.connect(i, src) });

SynthDef(\sine, { |freq, amp|
	Out.ar(0, SinOsc.ar(freq, 0, amp) ! 2);
}).send(s);


~fbus = Bus.control(s, 1).set(440);
~ampbus = Bus.control(s, 1).set(0);

~fspec = ControlSpec(48.midicps, 84.midicps, \exp);
~ampspec = ControlSpec(0, 1, \amp);

// ~noteR = NoteOnResponder({ |src, chan, A, B| ~ampbus.set(0.3) });
~bendR = BendResponder({ |src, chan, value| ~fbus.set(~fspec.map 
(value / 16383).postln) });
~touchR = TouchResponder({ |src, chan, value| ~ampbus.set(~ampspec.map 
(value / 127).postln) });

~synth = Synth(\sine, [\freq, ~fbus.asMap, \amp, ~ampbus.asMap]);

I will try to improve the pressure-amp relation, add pitch dependence  
to the amp control. Later add some NoteOn triggered ADRS, tailor the  
sound, add pressure and frequency dependence to the colour + some  
effects, yet later some MIDI control. I will report and most probably  
will have questions as I learn SC :-)

If the R2M is physically OK and as things stand, it seems I will not  
have to buy analogue hardware synth modules (VCO, VCA) :-)

Cheers,
