QUAD SAMPLE AND HOLD MODEL 264
POLYPHONIC ADAPTOR
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 diers 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).

First step: Oscillator Calibration (Quick Start)
A push switch sends either Auto-Tune Initial Tuning or command via the ART outputs to the oscillators. Both functions are
explained in detail in the 259t user manual, which also provides additional ART-related information worth knowing.
To quickly set up the 259t:
1 Connect any ART output to the 259t oscillators and set them to .ART mode
2 Let the oscillators warm up for a minimum of .30–40 minutes
3 Hold down the —the 259t will begin 264t tuning switch Initial Tuning, calibrating each oscillator one at a time.
The LED will turn o, then start blinking as it tunes the first oscillator.
4 Once tuning is complete, the oscillators can play notes via ART.
Auto-Tune can be sent periodically to correct tuning if it sounds like the oscillates are out of tune. (Beware that the fine tune knobs
on the 259t needs to be set fully CCW for the note center pitch) To send an Auto-Tune command short press the tuning switch on
the 264t.
Playing Notes
The ART Quantizer is tied to the function. When a is sent to the , the control voltage is Sample and Hold gate pulse gate input
converted into a note value and sent via ART to the oscillator.
• The determines the note length at the oscillator.gate pulse length
• In Track and Hold mode, the 264t ART output follows changes in input voltage .as long as the gate is high
