VCA / Comparator (VCOM)
[Module comprised of a single VCA from the Dual VCA (2VCA) and the Comparator section of the ÷ N Comparator (NCOM).]
Dual Transient Generator (DTG)
The DUAL TRANSIENT GENERATOR (DTG) provides two independent outputs with voltage controllable rise and fall times. This module is identical to the Dual Universal Slope Generator except that it does not have all of the front panel features. This module is a useful, space-effective unit to be used for many of the same functions as the Dual Universal Slope Generator. Common uses of the Dual Transient Generator are for simple “AR”-type envelope generation, as a dual voltage-controlled low frequency oscillator, or as a voltage-controlled clock (especially suitable for clocking the Touch Keyboard Sequencer or any of the Sequencer Programmers). These functions can be patched with the Dual Universal Slope Generator, but since many of the features are left unused in these patches, the Dual Transient Generator provides the same function while using less front Panel space.
Smooth / Stepped Generator (SSG)
The SMOOTH & STEPPED FUNCTION GENERATOR (SSG) is a complex multi-functional module to provide various slew and sample functions.
- The Smooth section will place a positive and negative slew (glide) on a changing input voltage for lag effects, voltage controlled portamento, and non-linear, low frequency filtering. With the CYCLE jack patched to the input, the unit will oscillate yielding a voltage controlled triangle wave LFO. A high level into the HOLD input will hold the current output level, whether the unit is oscillating or processing an external control voltage. This is identical to a track-and-hold function.
- The Stepped function can be used as a sample-and-hold with voltage controlled slew rate limiting. Slew rate limiting limits the size of the step at the output. For example, with a random voltage input and the step size set to a small value, the output is a random voltage that varies only slightly from step to step, gradually covering the entire range of the input voltage. No large changes in the output will be allowed. With the Cycle jack patched to the input and a trigger applied to the Sample input, complex staircase waveforms are generated.
- The COUPLER is an internal comparator comparing the Smooth and the Stepped outputs. This is useful for generating complex control voltages and for patching a random voltage generator. In fact, the Random Voltage Generator module is a Smooth & Stepped Generator internally patched to function exclusively as such. If random voltages are often used, a Random Voltage Generator is a more space-efficient module; but if seldom used, the Smooth & Stepped Generator can be patched when needed (and can be used for other functions when not used as a random voltage generator). Note that a Noise Source is needed for use of the Smooth & Stepped Generator as a random voltage generator.
Random Source (RS)
[The RANDOM VOLTAGE GENERATOR (RVG) produces random voltages which vary smoothly or in a step-wise manner. Random timing pulses are also available. Rate of change of all outputs is voltage controllable over a wide range.] The RANDOM SOURCE (RS) allies a Noise source with a Random Voltage Generator in one single module.
