Yes, the Buchla Electronics Musical Instruments Model 281e Quad Function Generator is in stock!

Manufacturer Description:
The Model 281e Quad Function Generator has four function generators organized in 2 pairs. All four normally function independently.

A momentary switch selects one of three modes: transient, sustained, and cyclic. An illuminated LED indicates the selected mode.

On receipt of a pulse, the output voltage ramps up to 10 volts at a rate determined by the sum of an applied control voltage and the setting of the attack time knob. If in the sustained mode, the voltage will stay high as long as the input pulse is maintained. If not in the sustained mode, or when the input pulse terminates, the output ramps down to zero at a rate determined by the sum of the decay voltage and the setting of the decay knob.

At the end of the decay, a transient pulse appears at the pulse output. If in the cyclic mode, the cycle now repeats.

The time range for both attack and decay is from .001 to 10 seconds.

In the quadrature mode, generators A and B (or C and D) operate in tandem to provide functions shifted by ninety degrees. The mode is selected with a switch and indicated with LEDs. An OR function can be invoked to generate more complex envelopes (ADSR).

The model 225e or the 206e preset manager can issue commands to store and recall the 281e's settings.

The 281e can respond directly to MIDI signals received by the model 225e MIDI interface.
