Tides is all about waves that go up and down, from minute-long cycles to audio rates… This module is Mutable Instruments’ unique take on the looping AD envelope generator – pushing this well-known trope to unknown territories.
The core of the module is a digital asymmetric triangle function generator, which can be used in AD and AR modes (for envelope generation), or looping (as a VC-LFO or VC-DO).
The triangle generator is followed by a wavetable waveshaper providing linear, exponential, logarithmic, sinusoidal, or arc-sinusoidal shapes for the A and D segments. Then, a second processor applies either a 2-pole low-pass filter to the waveform, smoothing its sharp edges; or a rubbery wavefolder, adding kinks and bounces to the waveform.
Power: 50mA @+12V / 20mA @-12V
Digital function generator
3 operating mode: AD envelope, looping (VC-LFO/VCDO), AR envelope.
3 frequency ranges for the main frequency knob: low (2 minutes to 2 Hz), medium (0.125 Hz to 32 Hz), high (8 Hz to 2kHz). This range can be widened by applying an offset on theV/OCTinput.
A large palette of waveforms
Shape control with CV input – covering various combinations of linear, exponential, or sinusoidal segments.
Slope/asymmetry (A/D time ratio) control with CV input.
Smoothness control with CV input: smoothes the waveform using a 2-pole digital filter, or adds bumps and kinks with a digital wavefolder.
The module can use an external clock or clean audio signal as a reference, and operate at a multiple of this clock (from1⁄16to 16x).
This allows, for example, the generation of (sub)harmonics from another VCO.
4 output modes
Different shapes. Each output produces a different waveshape: main signal (with voltage-controlled attenuverter), raw asymmetric triangle, end of attack gate, end of release gate.
Different amplitudes: Voltage-controlled dispatching of the signal to each of the 4 outputs.
Different times: Voltage-controlled phase or apex shifting of the signal.
Different frequencies: Outputs 2, 3, and 4 are shifted up or down in frequency relatively to output 1, creating chords or polyrhythmic LFOs.
