Roland Synthesizer System 100 - Original Roland Brochures

Roland Jupiter 6 & RE-301 Chorus Echo

YouTube via zibbybone

"Sort of a "two in one" demo for your viewing pleasure. One of my favorite things about the Jupiter 6 is its resonant mulit-mode filter. I've got the JP-6 set up in split mode with a 2 voice unision bass sound and a 4 voice polyphonic lead/pad both using bandpass filters. This JP-6 has the Europa upgrade which adds enhanced MIDI capabilities and imroves on the built in arpeggiator. A neat feature added to the arp is a polyrhyt mode. A single note will repeat at standard tempo. As you add notes, the clock is divided for each note. Kind of hard to explain, but watch and see. I forgot to turn off the RE-301's reverb at the beginning, but I soon switch to a completely dry signal. I then add the reverb, chorus (very nice for pads) and lastly the tape echo. If you listen in stereo (might have to add "&fmt=18" without quotes to the end of the URL), the direct signal & reverb are in left channel, tape echo in right and chorus in both. You can hear some pretty extreme wow and flutter on the echo in some parts. I hope I just need a new tape and not a new motor."

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...)

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...."
