Modules Breakdown:

501D DUAL OSCILLATOR MODULE combines two voltage controlled oscillator circuits in one double-width unit. The two oscillator halves enter a symbiosis in that they share some controls which affect both while other functions are individual to each oscillator.

Each oscillator has its own octave range switch (32’...2’ plus low frequency and wide settings, ‘wide’ augmenting the range of the tune pots to the whole 10-octave span of the oscillators).

The master tune control on the left side affects both vcos while the corresponding pot on the right controls the detune interval beween vco 1 and 2. Bipolar attenuators for frequency and pulse width modulation with their corresponding input jacks are separate as are the two pulse width controls.

The central waveform selector controls both wave outputs 1 and 2 while three additional output jacks provide sine, sawtooth and pulse waves of oscillator 2; the output area is completed by a white noise source. More individual wave outputs can be obtained by adding the 501E expander module.

The seven control voltage inputs allow control of frequency modulation and pulse width modulation of vco 1 and 2. Two more jacks control frequency (1V/oct) while the central cv input jack controls both oscillators at once.

502 D DUAL VCA module combines two separate voltage controlled amplifier circuits with each two modulation inputs, switch-able linear/exponential mode, switchable AC/DC mode (audio signals/control voltages), single, mix and ring modulator outputs.

The module can act as two independent mono or one stereo VCA, as dual channel VC mixer, as auto-pan module, as ring modulator and voltage controlled attenuator for control voltages.

Normalized connections:
· the right VCA’s gain mod. input A is daisy-chained to gain mod. input A of the left VCA
· the right VCA’s gain mod. input B is daisy-chained to gain mod. input B of the left VCA
· the right VCA’s signal input is daisy-chained to the signal input of the left VCA

This allows controling both VCAs by a single control voltage

511D DUAL ENVELOPE GENERATOR module in typical ADSR-Style with four parameters: attack time, decay time, release time and sustain level.

The time parameters range from 1 ms to approx. 20 seconds. A gate button allows for manual triggering both envelopes.

Trigger threshold of the gate input is ca. 1 volt, positive edge.

Two LEDs serve as indicator lamps for ’gate pulse present‘. 2 x 4 more LEDs light up during each stage of the envelope.

The envelope outputs serve as normal (0 to 10 volts) and inverted (0 to -10 volts) outputs.

Both envelopes are switchable from “Normal” to “Retrig” Mode

517S VOLTAGE-CONTROLLED HIGH/LOWPASS FILTER features a single high pass/low pass filter with voltage controllable cutoff frequency and regeneration.

526 REVERSIBLE MIXER is an active bipolar three channel mixer for audio signals and control voltages with master level control and both inverting and non inverting outputs.

In addition each channel has a dedicated on/off (‘mute‘) switch with status indicators.

„0“-position = no output signal present

“+10” position = output signal equals input signal (unity gain)

“-10” Position = output signal equals input signal (unity gain), but inverted.

544 CP UTILITY incorporates a couple of useful control voltage and logic functions in a CP sized module (4 units wide): · Two bipolar attenuators which double simultaneously as 2-channel mixer and signal inverter. If nothing is plugged into the inputs, 5 volts are present, so output A and B deliver a variable voltage between -5 and +5 volts and the A+B output delivers the sum of both to be used as a “level shifter” (for A or B).

· Slew limiter with dedicated on/off switch
· Gate delay
· 3-input voltage summer/inverter with 3 output jacks (2 straight, 1 inverted)
· 3-input gate summer/inverter (OR logic) with 3 output jacks (2 straight, 1 inverted) and status leds
· 3 leds indicating power supply voltages

Normalized connections:
· The voltage summer output is daisy-chained to the Slew Limiter input
· The gate summer output is daisy-chained to the Gate Delay input

569 QUAD SEQUENTIAL VOLTAGE SOURCE is an analog step-sequencer with up to 32 positions, arranged in four rows. Each row can be controlled absolutely independent from each other, so that the user has practically up to four separate sequencers at his disposal, each with its own clock - and reset-input jacks, and - at the same time - different running directions (up, down, random, and "ping-pong"). In addition the control voltage outputs can be switched between three ranges (2V, 5V, 10V, with the 2V and 5V ranges supplying a (to 1/12 V) quantized output voltage. Each step position has its own "step-mode" - switch to toggle the gate signal of the respective step position on or off. In the "Function" position it (again separately for the four rows) can defined as skip, reset or stop-command.

The sequencer modes in detail:

All four rows run in series to achieve sequences of up to 32 steps; only "Reset Input "1 and "Shift Input 1" are active then; as well as the switches "Direction 1", "Range 1" and "Function 1". With the "Direction" switch 2 in the "Down" or "Random" position the "ping-pong" mode (up-down) is activated. All four gate and voltage outputs supply an identical output signal.

Rows 1 and 2 run in series, as well as rows 3 and 4 (1 & 2 and 3 & 4 in parallel), so up to 16 steps divided in two sequences are possible here. "Reset Input" 1 & 3 and "Shift Input" 1 & 3 are active, just as the switches "Direction" 1 & 3, "Range" 1 & 3 and "Function" 1 & 3. With "Direction" switches 2 resp. 4 in position "Down" or "Random", the "ping-pong" mode (up-down) is activated. The gate outputs 1 & 2, 3 & 4 and the control voltage outputs 1 & 2, 3 & 4 supply each identical signals.

All four rows 1, 2, 3 & 4 run in parallel and independently from each other, all inputs, switches and jacks act separately, the four outputs deliver their own signal each. This is the "four sequencers in one" mode.

Sort of "preset-subset" of the 4x8 mode. All four sequencer-rows run always in parallel and in step, controlled by one common pair of shift and reset commands, just like a "four-channel-sequencer".

Another "preset-subset", this time derived from the 2x16 mode. The sequencer-rows 1/2 und 3/4 run always in parallel and in step, controlled by two common pairs of shift and reset commands, just like a 16 step "two-channel sequencer" - think 'stereo'.

569LE QUAD LAG EXPANDER is another companion module to the 569 which expands the sequencer's four rows by four lag voltage outputs (aka portamento). Each row has its own lag rate control as well as switchable on/off/gated mode and switchable lag function for rising or falling edge only or both.

569ESB SET INPUT EXPANDER BASIC expands the 569 by four switchable set inputs, one position per row can be specified.

The four push-button switches on the 569 ESB provide a way to manually access a stage instantly without stepping through all stages. This should be handy for setting up sequences, changing/fixing a particular note and for playing the sequencer on the fly.

All four inputs are daisy-chained: 1 2 3 4 = one signal can set all rows (the 569 sequencer in 4-channel mode) at once.

598CP TRIGGER CONVERTER / MULTIPLES converts S-Trig to V-Trig and vice-versa, and includes a very special cable and connector to make compatible the modern or vintage model Moog 962 and 953 Keyboards. Configurable for monophonic or duophonic operation.
