Tides 2018

Mutable Instruments

Digital tidal modulator — a function generator with three ramp modes (AD envelope, looping LFO/VCO, AR envelope), four output modes, and a wide palette of waveshapes with shape, slope, and smoothness controls.495

Capabilities 5

Clock Multiplier/Dividerclock-multiplier-divider
Can lock to external clock and operate at 1/16 to 16x multiple; FREQUENCY knob sets the ratio.495
Envelope Generatorenvelope-generator
AD and AR one-shot envelope modes; unipolar 0 to +8V output; gate-following AR sustain behavior.495
Function Generatorfunction-generator
Tidal modulator / function generator with AD-envelope, looping LFO/VCO, and AR-envelope ramp modes.495
LFOlfo
Cyclic ramp mode with bipolar output (±5V); frequency ranges from sub-audio to audio rate.495
Voltage-Controlled Oscillatorvco
Audio-rate cyclic operation with V/Oct tracking, selectable waveshape, and frequency multiplication/division output mode for chord generation.495

NameSignalVoltageDescription
Inputs (8)
CLOCKclock0V to 8VClock input for tempo or frequency-locked operation. FREQUENCY knob controls ratio between clock frequency and Tides output frequency; 1:1 at 12 o'clock. Can accept a clean audio oscillator signal as reference.495
Frequency CVcv495
Shape CVcv-8V to 8V495
Shift CVcv-8V to 8V495
Slope CVcv-8V to 8V495
Smoothness CVcv-8V to 8V495
TRIGgate0V to 8VTrigger/Gate input. In AD mode: trigger resets envelope to 0V and initiates AD cycle. In cyclic mode: trigger resets oscillator to start ascending phase. In AR mode: rising edge raises to +8V, falling edge falls to 0V.495
V/OCTcv-3V to 7V495
Outputs (4)
Output 3gateOutput 3: In Different Shapes mode, produces the end-of-attack gate signal.495
Output 4gateOutput 4: In Different Shapes mode, produces the end-of-release gate signal.495
Slope Outputmixed-5V to 8VOutput 2: In Different Shapes mode, produces the raw asymmetric triangle waveshape.495
Unity Outputmixed-5V to 8VOutput 1: In Different Shapes mode, produces the main signal with voltage-controlled attenuverter. In other modes, signal is routed/shifted as determined by SHIFT/LEVEL.495

Parameters 9

NameTypeRangeBehavior
AttenuvertersknobAttenuverters for the CV inputs (Slope, Frequency, Smoothness, Shape, Shift).495
FREQUENCYknob-4octave – 4octaveSpans ±4 octaves around the central frequency set by the Frequency Range button. In clock mode, controls the ratio between the external clock frequency and Tides' output frequency (1:1 at 12 o'clock). In one-shot modes, clockwise = faster.495
Frequency Rangebutton≤2000HzSelects the central value of the FREQUENCY knob: 1/8 Hz (movements), 2 Hz (rhythms and modulations), or 130.8 Hz (audible tones).495
Output ModebuttonSelects the relationship between the four output signals: Different Shapes, Different Amplitudes, Different Times, or Different Frequencies.495
Ramp ModebuttonSelects between one-shot unipolar AD envelope generation, cyclic bipolar oscillations, and one-shot unipolar AR envelope generation.495
SHAPEknobControls the shape of the ascending and descending segments. In the audio range, offers a different palette of waveshapes for more striking timbral differences; range is narrowed at high frequencies to prevent aliasing.495
SHIFT/LEVELknobIn Different Shapes mode: attenuverter on the main signal. In Different Amplitudes mode: selects to which output the signal is routed with smooth crossfading. In Different Times mode: shifts the apex of the waveform across outputs. In Different Frequencies mode: adjusts frequency ratio between outputs (1:1 at noon).495
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 PWM effects.495
SMOOTHNESSknobFrom noon CCW: 2-pole low-pass filter smooths waveform edges. From noon CW: wavefolder adds kinks and bumps along the slope. Range is narrowed at high audio frequencies.495
Zones
Smoothed
Folded
  • Smoothed -100–0%A 2-pole low-pass filter is applied to smooth the edges of the waveform.495
  • Folded 0–100%A wavefolder adds kinks and bumps along the slope of the waveform.495
