Tides 2018

Mutable Instruments

A module whose core function is ebb and flow — voltage going up then back down — usable as LFO, VCO, or AD/AR envelope generator.409

Capabilities 4

Clock Divider/Multiplierclock-divider-multiplier
409
Envelope Generatorenvelope-generator
AD and AR one-shot modes generate envelopes triggered by gate/trigger input, with controllable shape, slope, and frequency (time).409
LFOlfo
Cyclic mode generates LFO waveforms across a wide frequency range; four output modes allow polyrhythmic LFOs, phase-shifted LFOs, and more.409
Voltage-Controlled Oscillatorvco
In cyclic mode at audio range, generates VCO-quality waveforms with V/OCT tracking and external clock PLL.409

Jacks 5 — 4 in / 1 out

NameSignalVoltageDescription
Inputs (4)
CLOCKclock0V to 8VClock input for tempo or frequency-locked operation. FREQUENCY knob controls the ratio between clock frequency and Tides' output frequency (1:1 at 12 o'clock). Can also accept a clean audio signal as reference for harmonic generation.409
CV In (Slope/Freq/Smoothness/Shape/Shift)cv-8V to 8V409
TRIGgate0V to 8VIn AD mode, trigger resets envelope to 0V and initiates attack/decay cycle (always completes). In cyclic mode, trigger resets oscillator to start ascending phase. In AR mode, rising edge raises to +8V, falling edge falls to 0V.409
V/OCTcv-3V to 7V409
Outputs (1)
Outputsmixed-5V to 8VFour outputs whose relationship is set by the Output Mode button. Bipolar ±5V for cyclic signals; unipolar +8V for gates and envelopes. 14-bit DAC at 62.5kHz (31.25kHz in different frequencies mode).409

Parameters 9

NameTypeRangeBehavior
AttenuvertersknobAttenuverters for the CV inputs (Slope, Frequency, Smoothness, Shape, and Shift/Level).409
FREQUENCYknob-4octave – 4octaveSpans ±4 octaves around the central value set by the frequency range button. In clock mode, controls the ratio between external clock frequency and Tides' output frequency (1:1 at 12 o'clock). In one-shot modes, clockwise = faster.409
Frequency Rangebutton3-position button selecting the central frequency of the FREQUENCY knob: 1/8 Hz (movements), 2 Hz (rhythms and modulations), or 130.8 Hz (audible tones).409
Output ModebuttonSelects the relationship between the four signals generated on Tides' four outputs: Different shapes, Different amplitudes, Different times, or Different frequencies.409
Ramp Modebutton3-position selector: one-shot unipolar AD envelope, cyclic bipolar oscillations, or one-shot unipolar AR envelope.409
SHAPEknobSets the shape of the ascending and descending segments; in audio range mode, offers a different palette of waveshapes for more striking timbral differences.409
SHIFT/LEVELknobAdjusts amplitude/polarity of the first output in Different Shapes mode (attenuverter), or shifts amplitude/time/frequency between outputs in other modes.409
SLOPEknobSets the ratio between the durations of the ascending and descending segments (A/D time ratio). In audio range, uses a linear scale for smooth pulse-width modulation effects.409
SMOOTHNESSknobWaveshape transformation: CCW from noon applies a 2-pole low-pass filter to smooth waveform edges; CW from noon adds kinks and bumps via a wavefolder.409
