Macbeth Dual Oscillator

via this auction

"Macbeth Dual Oscillator for Eurorack Modular synthesizers. For those of you who don't know you need a standard eurorack case to power this unit, doepfer etc. Unit works great it's not very old and in perfect condition. I personally think this is the best sounding euro oscillator module on the market, it has a real classic vintage sound and honestly sounds fatter than a lot of vintage analog oscillators. Completely worth the money, some people gripe about macbeth prices but they are missing out!!! Simply the best and I've owned two macbeth M5s and can tell you the dual oscillator module sounds better, more gooey and warm and breathes with more life than the m5 oscs. I'm thinking this is actually the first used Macbeth Dual Osc to hit ebay??? I'm only selling to fund another big synth purchase and I'm selling off my euro stuff because I don't like patching all that much with little tiny 1/8th cords haha. These are $1299 new and here in CA there is crazy tax so don't miss out on the buy now..."

MOTU Volta on the B-Roll

"Volta is a pretty great invention in the world of modular synths. While it makes the visceral experience of patching something from raw into a slower more logistical experience, it makes the composing of music with the modular a much easier task. Plus there’s nothing better than being able to bring that modular perfectly in sync with Ableton Live and testing out different drum loops over the sound."

You can find the full post on the B-Roll. Some nice pics and audio there as well.
