Description

Polyphonic Quad Sample & Hold

Four independent sample-and-hold circuits, plus a specialized logic circuit for expediently implementing polyphonic patches.

Sample-and-hold’s are essentially one-cell analog memories. They are useful for “remembering” the instantaneous value of a control voltage (a detected envelope, for example), for generating equally spaced steps from a constant slope input (as from a 281t envelope generator), and for converting any continuously changing voltage (a random voltage, for instance) into a series of discrete values.

The 264’s sample-and-hold circuits have two operating modes: sample and track. In the sample mode, the value of the input is sampled and applied to the output whenever a pulse is received. The output remains at this value until the next pulse arrives. The track mode differs in that an input is applied to the output for the duration of the pulse. The output tracks the input until the end of the pulse and remains at a constant value until the next pulse.

To use the 264t as four independent channels set the separate/common switch to separate. A single CV can be set to all four channels by setting the operate/common to common and plug CV in the the back jack on the with right side.

The Model 264t includes a polyphonic adaptor, which performs the logic necessary to implement four-voice polyphony. Facilities are incorporated for fine tuning and f.m. modulating the oscillators; light emitters display the adaptor’s operation.

ART Quantizer

The four voltage control outputs are internally routed to a quad-channel quantizer with four ART outputs for use with ART-equipped oscillators, such as the 259t Complex Oscillator. A 12-stage switch selects the key, while the knob above chooses the scale: Minor (m), Chromatic (ch), or Major (M).
