CHORD MODE BUTTON - this button, when pressed, toggles the CHORD mode on and off. When CHORD

mode is active, 8 detuned copies of oscillator 1 are running. These copies are shifted in relative pitch in

musical intervals to produce chords. There are 64 different chords that are available. When the CHORD

mode is turned on, the upper row of the display will indicated the currently selected chord type. This

selection can be changed with the rotary encoder.

FOLD POTENTIOMETER - this potentiometer sets the amount of folding imposed by the waveform

folder. As this control is part of the analog waveform folder circuitry its setting is not shown on the LCD

display.

PERC MODE BUTTON - this button, when pressed, toggles the PERCUSSION mode on and off. When this

mode is active output 1 is passed through a digital amplifier whose gain is controlled by a simple enve-

lope. The envelope has a very sharp attack and an exponential decay. The decay rate is determined by

the DECAY parameter setting. The envelope is triggered by positive-going pulses received at the external

sync input jack.

SHAPE 1 POTENTIOMETERS - this potentiometer selects the waveform for oscillator 1 from the 8 wave-

forms in the currently selected wave bank. There is a smooth interpolation between the waveforms.

This setting is summed with the external SHAPE 2 modulation input to provide the actual selection.

LFO MODE BUTTON and LFO 1,2 LEDs - this button, when pressed, cycles through the enabling of LFO

mode for oscillators 1 and 2. The first button press turns on LFO mode for oscillator 2 only. The second

button press turns on LFO mode for oscillator 1 only, the third button press enables LFO mode for both

oscillators, and the fourth button presses turns off LFO mode for both oscillators. In LFO mode the pitch

of the oscillator is dropped by 7 octaves (frequency is divided by 128). When LFO mode is enabled for

oscillator 2 and quantization is off, the pitch of oscillator 2 is no longer affected by the COARSE and FINE

knobs. It is only affected by the PITCH 2 input and the RATIO control and input in this situation.

OUTPUT JACKS - the four rightmost jacks in the bottom row are used to output the following signals:

OUT1: outputs the oscillator 1 waveform after passing it through the nonlinear combination

process and the echo/delay effect. The signal is internally generated at 25MHz but is downsampled to

98KHz before passing through a DIgital to Analog converter.

OUT 2: outputs the oscillator 2 waveform. The signal is internally generated at 25MHz but is

downsampled to 98KHz before passing through a DIgital to Analog converter.

PULSE: outputs a two-level signal (0-5V) derived from the oscillator 1 or oscillator 2 waveforms

(the specific output depends on the particular PULSE mode selected).

FOLD: this is the output of the analog wavefolder.

PULSE/LFO 2 LED - this LED indicates whether the PULSE output is high (5 volts) or low (0 volts). When

oscillator 2 is operating in LFO mode, this LED no longer displays the PULSE output value, but instead

indicates the sign of output 2 (i.e. the LED is illuminated whenever output 2 is positive).
