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.
Mixer / CV Processor (3x1) (MPR)
[Note: Similar to the Audio Mixer (AMX), the Mixer / CV Processor's inputs and output are DC-coupled with blue jacks, indicating that they can process CV or audio. The other differences are 1) rather than a phase switch, IN 3 includes a single level and polarity control, and 2) the output includes a DC offset control.]
Frequency Shifter (FRS)
The FREQUENCY SHIFTER is an advanced model with several improvements over existing designs:
- Greatly improved signal-to-noise ratio
- Extremely high carrier frequency rejection
- A very clean sound down to very low signal levels (unlike conventional shifters which have increasing distortion at low levels)
- No squelch circuit and, therefore, no annoying dropouts or "pumping" action in the sound
Uses of the FREQUENCY SHIFTER abound. It can be used to frequency modulate natural sounds (from musical instruments, for example), to produce the "Leslie effect" of rotating speakers, and to synthesize other phase shift and vibrato effects. In concert halls, frequency shifters are often Used to control feedback . It performs special effects on human speech, excellent for "computer-like" or "alien-type" speech . One of its most dramatic effects is frequency shifting of an echoed sound, where delayed signals get successively fed back and shifted up or down to produce incredible arpeggios of multiple echoes. Such an effect can be produced with the FREQUENCY SHIFTER and a reverb chamber or tape delay . Quite similar (and other rather far-out) effects can be produced with the use of the Analog Delay module.
...[This] basic unit features a built-in oscillator (with 0 and 90 degree outputs) whose sine wave outputs provide for the smoothest and cleanest shifting... Additional features ... include output VCA's for both the UP and DOWN shifted signals, and an Output providing a COMPRESSED version of the input.
Control Module (C/M)
The CONTROL MODULE (C/M) is provided for economic utilization of extra panel space and as a low-cost source of manual triggers. Also included are two sections for attenuating control voltage or audio signal levels.
The CROSS-FADER (XFAD) is an equal-power cross fade unit. The module has two signal inputs. As one signal increases in level at the output under manual or voltage control, the other signal decreases in level at the output. This effect is used to accurately fade one sound in while fading another out. Cross-fading with voltage control permits a smooth transformation between two different timbres. If a sound and its reverberated image (available with the Wilson Analog Delay) are sent through the cross-fader, the reverb mix can be voltage controlled. This effect can be used to modify the spatial characteristics of a sound event, from immediate presence to distant ambience. In addition to the cross-fade function, a VCA controls the output amplitude.
