Mutable Instruments Tides
Tides, from Mutable Instruments, is a complex signal generator that can be used in many different modes. The structure is based off of the classic slope generators from the past, reminiscent of the Buchla function generators and the Serge Slope Generators, but with modern improvements. It has three modes, an Attack-Decay envelope, great for percussive sounds, an Attack-Sustain-Release envelope, great for keyboard envelopes or sustain sounds, and an LFO (looping envelope), that can extend from LFO rate to audio. The outputs allow for both Unipolar and Bipolar oscillations. What separates it from slope generators of the past is its ability to warp waveshapes while maintaining its core frequency. This essentially turns it into a wavetable oscillator with three different timbral controls.
Along with this is a built in VCA, and a Freeze input, which holds the voltage present when ever the gate is high. This can put Tides into the Sample and Hold or Track and Hold territory. All parameters are voltage controllable, for maximum integration with other Eurorack modules.
The grand collection of functions available in Tides essentially allows it to be a self contained synth voice, when paired with a CV keyboard.
With Tides Parasite installed, Tides also includes a built in Quantizer that works in each mode, an "additive"-like synthesis engine called "Two Bumps," and a random modulator called "Two Drunks." Visit the website for Parasites here.
- Output level CV input (digital VCA).
- Dual outputs: standard unipolar waveform, and “double-shot” waveform with a positive spike during the ascent and a negative spike during the descent.
- At audio rate, both of them have a different sound.
- Accurate V/Oct tracking with straightforward calibration procedure.
- Freeze input to temporarily hold the waveform.
- Clock input to lock onto a multiple or fraction of a trigger sequence… or audio signal, PLL-style.
In this demo, we begin by just morphing the waveshape knobs while in oscillator mode. Each of the three knobs affects a different part of the timbre, with the third knob cutting off to nothing (with Parasites installed.) A modulation source from Peaks (LFO -> slow triangle wave) is then patched into the third waveshape control. Frames is then switched into Sequencer mode, being clocked by Channel 2 of Peaks. These four sequencer channels from Frames are then patched into the two other waveshape controls, the Level VCA and the 1v/Oct input (with the internal Quantizer from Parasites enabled.) For a little bit of space, the final output is then patched into Clouds, being fedback for Size and Position modulation. A full morphing sequenced line with FX with only four modules!
In this demo, we are using Tides as a slow modulation source to modulate the filter cutoff of the second resonant filter of Shelves. Braids in CSAW mode is the sound source fed through Shelves. Two LFO signals from Peaks are patched into Tides' first two waveshaping inputs to demonstrate how these morphing frequencies sound at low frequency. A Clock is then generated from Grids and patched into the Trigger input to demonstrate Tides' ability to function as an envelope. The top button is the mode select knob, which can select between oscillator mode, AD envelope mode, and ASR envelope mode.
In this demo, we show how the internal quantizer works within Tides Parasite. To access the quantizer, long press the top button. It will begin blinking with green, and with presses from the mode buttons, it will scan through the quantizer presets. The menu counts upwards in binary, including no quantization, semitones, a major scale, a minor scale, whole tone, pentatonic minor, poor pentatonic, and fifths. (These were scanned backwards in the video.) To exit the quantizer mode, long press the top button again. The second section demonstrates how the mode "Two Bumps" can be used to generate a shepards tone. This is taken directly from the Tides parasites manual on Mqtthiqs' github account. "Put the oscillator in this "octaves" mode, put the width at noon and the frequency around 9 o'clock; 28 octaves will ring at the same time, many of them way outside the audible range. Now feed a slow sawtooth to the 1V/Oct input, and adjust its amplitude so that it is 1V (or 2 or 3... any round number of volts). Monitor the Bipolar output: you will hear a Shepard-Risset infinite glissando."
