"Resonator network", Preset for Gotharman's LD3
video upload by Meska
"Since the last update and the posibility to modulat the SPAN parameter of the resonant EQ, i make a preset, with 7resonant EQ in series i build a resonator network.
The exiter is noise burst, prodiuce by the clap oscilator models going in to a bandpassfilter.
You can change the sound prodiuce with the folowing knob:
knob 1 : exiter filtering
Knob 2 : attaque of exiter
Knob 4 : feedback of resonator
Knob 5 : Attaque of the filtering envelop
Morph: resonator geometrie

What is Modulation? (Modular Synth 101 | Part 9)
video upload by Musical Miscellany (Poorness Studios)
"For the next episode in this introduction to modular synth, I take a closer look at modulation. Everyone always talks about it, but what is it? Modulation is simply using a signal to control another signal. It's a simple concept but it puts the fun in modular synthesis."

Melodicer vs. Black Sequencer - one or both?
video upload by John Schussler
"I haven't spent much time with the Erica Synths Black Sequencer, and I noticed in a thread the other day somebody mentioning it serving as a substitute for the Vermona Melodicer.
Say what? I have a Melodicer, and it's the cat's meow. Can it really be supplanted by the Erica Synths offering?
They're big modules, so it's worth asking the question. Which is what you have here...me asking the question of whether I keep both or just one.
Source VCO is an Acid Rain Chainsaw. No envelope, just the output gates from the sequencer’s going to a Bard tube LPG.

The synth overlay is merely resting on top under the knobs, not permanent by any means and easily changeable for whatever your needs may be. An absolute killer synth that oozes Oberheim tone for days."

"Vintage Solina String-Ensemble Mk2 synthesizer, the mono version and for many the best version of the series. The synth is working fine and sounds wonderful! The service manual and even the spare fuses are sitting untouched under the lid.
Cosmetically it’s in very good condition too. There are some small scratches and little wear and tear, the wooden case has some signs of use, but overall it’s a nice example. Please check the photos for a good impression of the condition.
It’s a 220v version and the serial number is: 0135363."

Wersivoice FM76 & Wersi WV30 Wersivoice Rotor/String Effect Cards
Wersivoice FM76 video upload by hi there its me
"Vintage Chorus/Vibrato from the late 70s
- demonstrated with Ableton's Operator (Sine/Squarewave)
- no effects added
- beautiful to warm up your digital synths
- also works great with guitars, vocals..."
Note the video above is not for the listing below and it actually uses a different card. See the update from Ohm Studio below. There were different versions of the PCBs used by Wersi. Read on for details.

"These WV30 rotor/string cards are used and tested from a Wersi Arcus and are suitable for all CD range organs. Not suitable for any DX range organs."

Earlier ensemble fx used TCA350 BBDs like the Eminent Solina, Logan string melody, Crumar Stringman etc.
American and Japanese designs tended to use Panasonic (Roland used the MN300x a lot. Like in Juno choruses too).
I never really notice a real difference in sound between those BBDs IF the circuit is more or less similar and based on the Solinas, ie using 3x BBDs modulated by 2 lfos, one at 6hz and one at 0,6hz.
Roland ensemble fx do sound very different than the rest, but IMO it’s not because of the uses of Panasonic BBDs but because of the circuit design that is not based on the classic eminent design.
I do think however that the Bohm Phasing rotor and the Wersivoice are the lushest you can get (except, most probably for Jurgen Haible Triple Chorus, which unfortunately I never had a chance to hear. From what I've read the Bohm was a huge influence in his design).
So to make a long story short: no it’s not the same but I’m quite sure it would sound nice because it looks like it’s the classic design."
