Hi Drake,The controller plays midi files either from the SD card or through the midi input. I imagine you could also play notes in real time through the midi input. The midi (note on, note off, volume, etc..) are output to a fiber optic transmitter. The fiber cable connects from the controller down to the base of the DRSSTC driver which receives those pulses and fires the gates of the IGBT's which of course switch power to the primary coil. In my case, I'm using a Steve Ward Universal Driver (one of the later revisions). So in the end, the coil is being driven directly by the midi. It is of course sparks creating the sound and sparks are only so good as a sound source, but it's quite fun and interesting to listen to. I'm not exactly sure on the frequency range you've asked about. There are of course limits, but that is mainly the coil itself and switching capability of the IGBT's themselves.

Hi, as an amateur keyboardist and producer I'd be very interested in this. I think that if I were ever to take an act on tour that a midi DRSSTC would be a great way to attract people to an event! Is this something that you load midi files on to, or are you able to play notes in real time? Also how does it translate midi into audio? I'm not terribly familiar with midi, but when dealing with it in a DAW (digital audio workstation, protools or ableton etc.) you always need a virtual instrument to translate it into audio. If it just translates the midi straight into audio somehow that's fine because the TC 'sound' fits nicely into electronic music. Just out of curiosity what's does the freqency response curve of say the DRSSTC in the video on 4hv look like? As in where does the volume start to roll off in the very high and low audio spectrum? Lots of questions, Drake _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
