Hi all

I finally gave in and decided to post footage of me testing my OMG super secret musical DRSSTC. I designed it last year as a paid commission for a Danish arts group who wanted a chorus of six musical coils that could be played by MIDI. I made a single prototype to test it here, but they ran six coils together in the final system, built by Finn Hammer over in Denmark.

What I made was an adaptor board that connected the internal tone generators on a Roland JX-8P synth to one or more DRSSTCs. The board converted the volume envelope to burst length, so the harder you pounded the keys, the bigger the sparks got. Hitting a high pitched note hard would blow the fuses, and the MIDI arrangements had to take this into account.

Since it was a paid job, I guess I'd have to get their permission to show you the schematics, but I think I'll get away with pimping the movies now. I don't think I ever posted them on the forum before, although I might have posted in the #hvcomm chatroom.

That's awesome! I really want to see a video of all six going in harmony! Did you have to sheild the Roland?

That thing is...uh, FREAKIN' AWESOME!!!

I've heard about that and was planning to do that with my coil, but I'd never seen it done! "Sweet" doesn't describe! After that, I'm going to see if I can figure out how to hook my Strat into my DRSSTC. Talk about "electric guitar!"

omg wuv j00 steve! brilliant! =)

I've never built a DRSSTC, and probably never will (too noisy)

, but when I finish my digital electric 'cello project (of which a significant part of the system Avi correctly called an "analogue phased locked loop" LOL), I'm sure I'll have some SSTC goodness to go with it.

Maybe I can get corona to spray off the strings, too.. heh, yeah, right. =D

Yeah, you must have posted it in the chatroom, because I have had those movies on my computer for quite some time. Very cool! It has a neat sound, and interesting dynamic characteristics.

So, when does the SSTC synth VST plug come out?

All,

Steve built the controlling electronix, I built the coils and organized the venue. J.S.Bach wrote the music:

At the premiere, the music was written by Palle Vang, another short snip:

Funky wrote ...

Did you have to sheild the Roland?

In a way. The Roland did not fare well with the back EMF trough the 6 coax signal lines to the controllers, so I built a fiber optic connection instead.

Cheers, Finn Hammer

Great work! I actually thought I could be the owner of the first "musical DRSSTC" with my nanoDRSSTC, but as I see now, you have been building one before I only had the idea...

very great work steve, now im really impressed.
if you cant show us the shematics, can you explain it a bit more how it actually works? im very interested in building this musical interrupter

from what i understand the on time stays the same all the time and you produce the sound by variing the off time between the cycles. thats not too hard to build with a simple pll and a lot of keys, but with a real midi input its difficult i think
