Three modes: one shot AD envelope (green LED), Loop mode (LED off), one shot AR envelope (red LED). In envelope modes the module requires a trigger signal.
Three frequency ranges: low (20min-5Hz, green LED), medium (0.05Hz-300Hz, LED off), high (8Hz-10kHz, red LED). The high range is optimized for audio and the shape/slope parameters have different characteristics. In addition to the range switches the frequency is controlled with the frequency control in arange of +/-4 octaves. There's a 1V/octave input and a FM input with polarizer. When the FM socket is unused the polarizer will act as fine tune control.
Three voltage controlled parameters control the wave form; Shape determines the characteristic of the wav, provoding different combinations of linear, exponantial and logarithmic for the rising and falling segments of the wave. Slope controls the balance between rising and falling wave. Fully counterclockwise the attack is null and the release has the length of one cycle (vice versa in fully clockwise position). In center position both segments have same length. Smoothness has two functions: in center position nothing happens, left of center it acts as a 12dB lowpass filter's cutoff control; right of center position it's a wave multiplier.
In loop mode a gate or trigger at the trigger input will reset the phase of the wave, in envelope mode it will fire the envelope.
A "high" signal at the freeze input will hold the wave form at it's current position.
Clock: the AD/AR cycle's frequency can be synchronized by clock. If you pressed the range button for one second you will enter PLL mode in which the tides will follow the clock frequency and the frequency control will determine the divisor. Both clock division and multilication is possible.
Level input acts as VCA for uni- and bipolar outputs when a cable is connected.
High-tide is an end-of-attack output, generating a pulse till the start of a new attack. Low-tide is an end-of.decay/release output providing a gate signal with the duration till the start of next decay phase.
Unipolar output generates voltages from 0-8V, bipolar output +/-5V, both waves are way different, even acoustically. Especially the bipolar output is cool for crazy envelopes.
