Buchla Auxiliary OSCillator Card Expander Card for Buchla Music Easel

The Auxiliary Oscillator Card for Music Easel: The Return of the Aux Osc Card!

Buchla Music Easel users remember fondly the BEMI-Era Easel Aux Expander Card, which added an auxiliary modulation source which could also be used as an audio rate oscillator, as well as CV routing and EG control features! With full CV control of all parameters, the original Aux Card was the perfect companion for a Music Easel, expanding its versatility and patchability.

Now, the Aux Card returns as the Aux Osc Card - A new Auxiliary OSCillator Card which perfectly compliments the current generation Music Easel Modern, Retro, Easel Command, and Anniversary Edition. Buchla has been hard at work designing and improving on the original, adding key new features:

• Adds an additional Modulation Oscillator
• Adds CV Multiplier and Switch Control
• Works with ALL Music Easels and Easel Commands built after 2012

The new Aux Osc Card builds on the legacy of the original Easel Aux Expander card:

• Since EG CV inputs were added on the 208c's front panel, the EG CV inputs on the old Aux Expander card have been replaced with a CV Multiplier with a knob that controls multi amount
• The Pulser input, also now on the front panel of 208c, has been replaced with a random pulse input!
