The Encore Universal Event Generator is a Synthesis Technology, MOTM compatible module designed to be a versatile and useful addition to an already great modular system. The UEG can be used as an envelope generator, a complex LFO, or as a step sequencer.

Eight stages are provided with adjustable time and level for each stage, and they each have an LED which indicates the relative voltage output for that stage.

The top switch controls the major modes of the UEG. LOOPONLY mode will force the UEGto cycle between the loop points. This is essentially an LFO.

ONESHOT mode will cycle through all eight stages once, regardless of the duration of the gate input.

GATED allows a new set of options controlled by the second switch. In this mode, the module will start the envelope when it receives a gate, but it will also loop as long as the gate is held. Once the gate is released, there are two ways for the envelope to end. In RELEASE mode, the UEG will complete the current stage, then jump immediately to stage 8. In FINISHLOOP mode, it will simply complete all the stages before stopping.

The top position of the second switch is the STEP mode. In this mode, the UEGtakes on a whole different personality: it becomes a step sequencer! It will advance through the 8 stages for each positive pulse on the GATE input.

The START and END loop switches allow the UEG to start a “loop” anywhere from stages 2 through 4, and end the loop between stages 5 and 7. These are used in LOOPONLYmode and in GATED mode.

The output waveform can have one of three slopes: linear, log, and step. These are shown graphically on the front panel.

The UEG also has a MANUALGATE button, useful to trigger the UEGwhile setting it up.

The four 1/4″ jacks along the bottom are the two inputs and two outputs. The leftmost jack is the GATE input and it requires a fairly clean pulse or squarewave input. (A Triangle wave will also work, but it needs to be fairly fast.)

The next jack is the TCV, or Time Control Voltage input. A 0 to 5 volt input will modulate all the time values to greater values.

The OUT jack is the main output waveform. It is a 0 to 5 volt analog voltage that corresponds to the front panel settings.

The TRIGOUT jack is the rightmost output and will fire off a short pulse at the conclusion of stage 8. It it also a 0 to 5 volt signal. This is useful to trigger other events in a MOTM system. For example, it could be used to trigger a second UEG to behave as a 16 stage sequence or envelope. In LFO mode the TRIGOUT can output a pulse for each stage of the LFO or at the end of the LFOcycle. All current users can have this update at no charge if they send us their UEG postage page both ways.

Modifications: Jack panel hardware changed to match the Switchcraft washers and nuts used on other MOTM modules. Added panel nuts to the switches, being very careful not to overtighten and stress the board. (They just didn’t look right without them.) Actual photo shown.

From the Encore Electronics website:

The Encore Electronics Frequency Shifter is a hybrid analog implementation of the sought-after frequency shifting effect. A RISC microprocessor is used to generate a highly stable quadrature oscillator which is then used with analog multipliers to generate the frequency shifting effect. The quadrature oscillator outputs are analog signals from the output of a DAC and the audio input signal is never digitized and stays entirely in the analog domain.

This unusual device will produce effects ranging from the subtle to the extreme. For example, by employing the simultaneous up and down shift outputs, the on-board feedback controls, and a slight amount of shift with the fine-shift control, a stunning stereo infinite phasing effect is possible. Small shifts with the fine shift control will also produce lush vibrato and rotating-speaker-like effects. Larger amounts of shift can result in unusual and often bizarre inharmonic modifications of an input signal that must be heard to be believed.

The frequency shifter can seriously warp any input signal, from keyboards to guitars to vocals to drum machines.

The Encore Frequency Shifter features two frequency shift controls (coarse and fine), and is a through-zero design. The UP output will shift up when the coarse knob is greater than 12 o’clock, and will shift down when less than 12 o’clock.

It also features an input scaler capable of handling signals from line-level up to modular levels, two feedback controls for added sonic variety, and a CV input scaling control. It also has two controls to adjust the level of the quadrature oscillator’s outputs. There are two inputs (one for audio signal and one for a frequency shift control voltage) and two outputs, one for up-shifted signal and one for down-shifted. The Encore Frequency Shifter is capable of continuous frequency shifting from 0.075Hz up to over 2000Hz. Carrier feedthrough is more than 50dB down with a properly scaled input signal; no companding is employed.

The frequency shifter operates by altering the frequencies of an input signal. The device shifts all frequency components of the input signal by an equal number of Hz. With this kind of shifting the harmonic relationships in the signal are not preserved. This is unlike a standard pitch shifter, which shifts all frequency components of an input signal by the same ratio, thus preserving the signal’s harmonic intervals.
