Oberheim SEM VCF Clone Module for Eurorack Format Modular Synths

via this auction

"Oberheim SEM 2pole state-variable filter clone professional built using audiophile grade components.

Some highlights on the controls:
Variable notch control
4 inputs for fading and mixing
bipolar attenuator for cut-off frequency as well as a simple attenuator of frequency
Resonance control

Built with the following component "upgrades":
Original spec'd FETs (2N4302)
Conductive plastic pots
silver mica filter cap
Elna Silmic II caps
Screened cable on outputs and twisted pairs on inputs to reduce on noise.
3.5mm Lih-sheng jacks

Mint...This was racked once for testing and calibration. Listing as used due to this being built in by a professional and not manufactured in a larger scale facility. Power cable is included with sale. Requires +/-12V power supply (Euro power headers)"

According to modulargrid: "Oberheim blessed SEM Voltage Controlled Filter pcb by Jeff Farr. Panel design by Clarke Robinson (clarke68)."

Side note: I created new Clarke Robinson, Jeff Farr, SynthCube & David Ingebretsen channel labels. David does not appear to be involved in this design, however I found him looking up Clarke Robinson in previous posts and decided to create a channel for him. David Ingebretsen is the man behind the new Steiner Synthasystem. He worked with Nyle Steiner on recreating the modules for the new system.

Note what he has to do at 1:42. How difficult would it be for manufactures to add a slot to rest your iPad in?

"This is my rendition of Elton John's 'Funeral For A Friend' using only an iPad 2, Axiom MIDI controller and my piano. I wanted to see if it was possible to recreate as closely as possible the intro to FFaF using just the iPad, and this is what eventually came of that. While not absolutely perfect, I think it gets the point across! :) BTW, NO sampling or recorded waveforms were used here - it's all synthesizer programming like the old days!

The synth apps used are:

Beepstreet Sunrizer (wind effect) [iTunes]
Moog AniMoog (howling sounds) [iTunes]
Arturia iMini (Bell) [iTunes]
Arturia iSEM (Main Brass-synth sound) [iTunes]
Bismark BS-16i (Strings, additional brass sound) [iTunes]
Baldwin L1 piano (real!)

Thanks for watching/listening!"

Corsynth C106 - Percusive Sounds

"Few percussion examples using the snappy C106 envelopes.
The bass drum sounds were created using Env1 to control the VCA and the second Env2 to modulate the pitch of the VCO.
The open-closed hit-hats were created using the Decay CV input connected to the 1V/Oct keyboard output , higher notes creates longer decay times."
