Bohmworld

You can find everything Böhm at Böhmworld.
The site is in German. You browse the site in Googlish here.
Anyone know if they are the same company that brought us the Boehm SoundLab? I did a quick search on the site and didn't see it.

Note that Böhm also brought us the hobbytron. via Wulfhard:
"This was a DIY-kit "to make appetite" for the bigger Boehm-organs and for testing your solder skins, because Dr. Böhm organs where sold as kits. So if you finished the "Hobbyton", you could start with a kit of a "Starsound" or other real ones - rather optimistic, if you look at the guts" You can hear an mp3 of it here.

Also via Wulfhard:
"This crazy guy [crazy is a good thing :)] got a 1977's kit of a Dr. Böhm Organ in the year and built it up in 2006-2007 (Dr. Böhm got bankrupt in 1990 at the end of the home organ boom - it's said that they had more work on repairing failed DIY-kits than selling new ones...)

http://www.boehmworld.com/fntbul.htm

The 3x keyboard is made of 3000 pieces already - complete organs could be 30.000 pieces in total (at the price of a Mercedes Benz). But they could be build up in chunks, for example one manual and one oscillator first - you received the kit parts in a kind of subscription. It's not known how many begun kits are rusting in german cellars...."

Roland S-330 used as an advanced virtual analog synth

YouTube via zioguido
"The Roland S-330 is an old digital sampler (1986) and is quite a piece of useless gear today, infact it's being sold for a few dimes on ebay [link] and on the classifieds. I happen to have one, it hasn't been used for years... but I remembered that it had some nice synthesis features other than its limited sampling possibilities, praticularly I remembered it had a nice analog-like filter, pretty good sounding for the days.

This video shows how this machine can be used without samples, as a stand-alone primitive virtual synthesizer.

First I load the OS, then I sample 400ms of silence, then I use the 'wave draw' function to draw my waveform and loop only what's showed in the wave window (that is, most of the sampled data won't be used).
The TVF (Time Variant Filter, as Roland used to call it) is the most interesting part. It also offers an 8-stage envelope.
With the patch parameter page I can set the unison mode and use the detune for a fatter sound.

What you see here is what is output from its video socket, and what you hear is what is output from out #1.

I was about to throw it into the garbage! :)"
