About the original topic: Organ Swell shoe volume control. Soon I hope to build a shoe control myself, but for a board I ordered and which was probably not made with midibox. But I have the same problem: the shoe contorl cannot turn the potentiometer through all it's range. Can't we do this: Use a AD-converter to make the signal of the potentio meter digital. But use not an ordinary 0 V and 5 V for min / max value but 0 V and the maximum volt you have as output value. Then you can built a circuit to cast the digital code to the right input pins of MIDIO128, or use a DA-converter with 0V and 5V to transfer the digital code back to the right voltage. Comment on mimimum volume value: In midio128 when adressing the pins, you can select minimum and maximum output (and all other values). (ie no problem) When using analog input you could set op the volume shoe in such a way that the minimum value is not 0V. When using jOrgan (with soundfonts or Gigasampler) ( http://www.meiers.net/sven/jorgan/ ) you can set a cut-off and volume for closed swell, but I don't know if this is the maximum or minimum value. I don't work with Hauptwork (yet), so I can't tell you about that. I hope this works and will tell you when I have done it myself.
