Buchla - Music Easel Aux Expander

Buchla - Music Easel Aux Expander - a lot of Easel-users have already wondered if it would be possible to enhance the module via the cartridge insert. The expansion card adds a lot more which had been in the background without changing the original Easel-concept.

Buchla - Music Easel Aux Expander - Add more functions to the already versatile Music Easel via the Program Card connector!

The Aux Card offers an auxiliary modulation CV source and noise source in low range and a CV/audio oscillator source in high range that can be mixed with the noise source. The noise source also can be filtered. All these parameters are CV controllable. In low range this auxiliary modulation oscillator allows the 208’s Modulation Oscillator to assume audio duties and can be used as the modulation source for a variety of uses. In the keyboard bus setting, it provides a tuning reference for your 208 or can be controlled with internal bus capable 218e keyboards.

The makers have also given you more control with more inputs. They’ve added one more pulse input and give you a choice of switchable destinations. They also added switchable control of timbre pot and switches via the “to card” inputs already on your 208. Did you know you could CV control switch settings? Destinations include the timbre wave shape, the Modulation range, gate source, the VCA LPF mode, the Modulation wave shape and Modulation Variation.
