I don't know what's wrong with the likes/dislikes on this video. Analytics shows 24 likes and 0 dislikes, while the video currently shows 3 likes and 29 dislikes. There seems to have been a glitch at some point.

Multitracked Wersi EX20 with Ibanez SDR-1000 reverb. This synth is capable of some highly unusual sounds when (in)correctly programmed, so I thought I'd showcase that side of it. It's sort of a half tribute and half parody of 70s computer music (i.e. Jean-Claude Risset, John Chowning, etc.). I find that sort of music tends to be sometimes brilliant and sometimes ponderously arbitrary (at least from the listener's perspective), so I tried to get a little of each in there.

Due to the bizarre user interface and poor/unavailable documentation, I think very few people have programmed these synths to this extent. At the time I think I only had the German user manual. I have the English manual now, but it omits much of the sound programming stuff.

Most of the interesting territory comes from doing strange things with the pitch and amplitude envelopes. Each stage of the envelope can be assigned a "module" that takes two parameters and does some function like noise modulation, increment, delay, linear or exponential rise or fall, loop, etc. It's even possible to make nested loops. These things don't necessarily behave the way you'd expect (are these undocumented features or bugs?), so it's basically a trial and error process, but the results can be very surprising. Recorded 2010?

Check the (NiCd) memory backup battery if you own one of these. They can leak and cause damage."

"The Wersi is a very deep synth, even today, has an analog filter and uses beautiful additive synthesis, with lots of envelope modulations possible..."

Curious how deep these are. Wersi's are known for more preset auto-accompaniment type machines.  You can find some details in this previous post.

  1. Thanks for posting this. I have the user manuals in both English and German, as well as the service manual. I'll be posting scans of them shortly, along with a detailed technical description. I've been wanting to take care of this for a long time, so thanks for providing some much needed motivation!
