Thanks for the compliments guys.

Are the tabs fairly responsive, by that I mean, can you make quick changes and even "glide" your finger across several stops rather than pressing each stop individually and more slowly?
Right now there's no spring installed. The tabs (simply by their weight) sit as low as possible, the metal thing at the back of the tabs just touches the microswitch. The travel of the switches with this setup is less than 1mm, it feels very natural, "stop glissandos" are easily possible. I'm thinking about installing small springs for each tab, but it may not be needed, I'll see how this setup works in practice.

I use a hwce board from midiboutique. One channel for pedal, two for the manuals, one for stop tabs and switches.

I haven't measured the total current yet, that's coming today. For this reason also, I only had them on one by one. They draw about 15mA each. Even with 41 LEDs that should be safe. My power supply for the MIDIbox is 9V 1A. I'll check the temperature of the drivers as well, thanks for the tip.

The stop switches are "Repeated event toggles" type, as they are momentary switches. The console itself is passive, everything is done by Hauptwerk. When the state of a stop switch changes in Hauptwerk, it sends out a MIDI message, which is captured and decoded by the MIDIbox unit, and the state of the lamp is changed accordingly. The stop switches on the console are just another way to change the state of the stop switch in Hauptwerk. Having it with crescendo or combinations is simple matter as the stop switches in Hauptwerk don't know why they have come on. Whatever way they come on, the MIDI message to set the lamp on is generated. This seems to me the cleanest setup. The only disadvantage is that I can't use the console without Hauptwerk. Why would I want to do that?[/quote]
