I use a BCF2000 as well, and I have to say, this is the best thing you get for such a price. I absolutely love it, and would even pay trice the money. There is nothing more useful than motorized faders, especially if you're blind like me. Its effectively a tactile display, 8x128, pretty cool! :-). I actually did things like "visualize" certain wave forms (like Sine and so on) using a specialized Class for the BCF I wrote for SuperCollider3. In the end, I added a "zoom" and "offset" rotary and set the first 3 buttons to switch between waveforms, and really had a perfectly cool tool for teaching blind people about continuus waveforms. And its damn fast, the reaction time of the motors is amazing. Its truly wonderful how one can "ab"use technology at times. :-) // Init MIDI and tell BCF about MidiOut MIDIClient.init; MIDIIn.connect(0, MIDIClient.sources.detect {|src| src.name.find("BCF2000").notNil }); BCF.midiOut=MIDIOut(0, 0); "aconnect 128:1 72:0".unixCmd; // Hack necessary to get midiOut working // View sin/cos/tan with variable resolution (knob 1) and offset (knob 2) (rotary group 1) // Use key 1 through 3 to change the waveform and key 4 to exit ( var sliders, resolution, offset, function, keys, draw; function=\sin; sliders=Array.fill(8, {|i|BCF(\slider, i+1, \bipolar)}); keys=Array.new.add(BCF(\key, 1, \midi, {function=\sin; draw.value})) .add(BCF(\key, 2, \midi, {function=\cos; draw.value})) .add(BCF(\key, 3, \midi, {function=\tan; draw.value})) .add(BCF(\key, 4, \midi, { resolution.free; offset.free; (keys++sliders).do{|bcf|bcf.free} })); resolution=BCF(\r1, 1, [8, 136, \lin, 1], { offset.spec=[ 0, resolution.value-8, \lin, 1, min(offset.value,resolution.value-8)]; draw.value }); draw={ sliders.do {|slider,i| slider.value = (pi*2/(resolution.value-1)*(i+offset.value)).perform(function) } }; offset=BCF(\r1, 2, [0, resolution.value-8, \lin, 1], {draw.value}); draw.value // Kick off ) The BCF class can be found at http://delysid.org/sc/BCF.sc (and JITLib support for BCF at http://delysid.org/sc/BCFProxyControl.sc). -- CYa, Mario
