Modulation with AD looping envelopes

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.

What sets this 2018 revision apart from its predecessor is the introduction of additional output modes, producing variations (shifted in amplitude, time, phase or frequency) of the main signal.

And of course, a redesign from scratch focused on accuracy and audio quality.

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 the V/OCT input.

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.

External clocking/PLL:
The module can use an external clock or clean audio signal as a reference, and operate at a multiple of this clock (from 1/16 to 16x).
This allows, for example, the generate 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.

All inputs: 100k impedance, DC to 7.8kHz.
SLOPE, SMOOTHNESS, SHAPE, SHIFT/LEVEL input range: +/- 8V.
V/OCT input range: -3 to +7V.
TRIG and CLOCK input range: 0 to +8V, protected.
16-bit CV capture.
Internal processing: 32-bit floating point.
CV Outputs: 14-bit, 62.5kHz (31.25kHz in different frequencies mode).
Output levels: bipolar +/- 5V for cyclic signals; unipolar +8V for gates and envelopes.

Features, controls, I/O

  • Cycle mode selector: single shot AD, single shot AR, looping (VC-LFO/VCDO).
  • Frequency range selector: low (20 minutes to 5 Hz), medium (0.05 Hz to 300 Hz), high (8 Hz to 10kHz).
  • Frequency control, with 1V/Oct frequency CV input.
  • Exponential FM CV input, with attenuverter.
  • Shape control with CV input – covering various combinations of linear, exponential, or raised cosine segments.
  • Slope/asymmetry (A/D time ratio) control with CV input.
  • Smoothness control with CV input. From 0V to -5V, smoothes the waveform using a 2-pole digital filter, from 0V to +5V, adds bumps and kinks with a digital wavefolder.
  • Unipolar CV input controlling output level.
  • Trigger input, which works as a trigger in AD/AR modes and a sync/reset in looping mode.
  • Clock input to “tap” or “ping” the LFO and envelopes, or to lock the VCDO frequency through a PLL. In these cases, the frequency control acts as a frequency division/multiplication control.
  • Freeze gate input to stop the oscillator and hold its output.
  • High tide and Low tide gate outputs for chaining/quadrature operation, or other applications such as gate delaying.
  • Unipolar (8V) and bipolar (+/- 5V) outputs, with a distinct shape/character.

Technical characteristics

  • All inputs: 100k impedance, DC to 500 Hz for shape/slope/smoothness, DC to 3kHz for FM, DC to 24 kHz for level.
  • 12-bit CV acquisition with separate power supply for converters and references.
  • 16-bit CV generation, 48kHz sample rate (12.5kHz in the lowest frequency range).
  • Cortex-M3 ARM processor.
  • Open-source hardware and firmware.
  • 14-HP.
  • Easy firmware updates through an audio interface.
  • Current consumption: +12V: 55mA ; -12V: 5mA.
