Orgon Systems Enigiser

via this auction

"The genuine Orgon Enigiser of 1997, NOT A CLONE !

Very RARE : only 60 to 80 units made around the world... This one is number 0051 (engraved on the back)

It doesn't sound like a clone, it's far more nasty, unpredictable with its own sound signature.

Very unique features :

- 15 types of analog filters

- 2 built in overdrives : one in the VCF and another in the VCA

- Saw width shaping in the VCO

- 3 enveloppes

- semi-modularity with busses (not patch cords)

- Nasty, gritty, angry sound, very alive !

One potentiometer is broken (Pulse width modulation level), you can replace it with a 100k pot."

Bad Gear - SERUM

"Welcome to Bad Gear, the show about the world's most hated audio tools. Today we are going to talk about SERUM. Is this cpu hungry software synth released by Steve Duda s company XFER the industry standard for wavetable synthesizer s, dubstep wubs & wobbles, EDM synth donks or are there better alternatives out there when it comes to modern VST instrument s.
