A new synthesis technique (polyBlep) is used for generating an alias-free, variable slope triangle at audio rates.


Initial release.



Sheep is an unofficial firmware for Mutable Instruments’ Tides which implements wavetable synthesis. This update completely replaces the stock firmware and turns Tides into a new module. It is not possible to run this firmware side by side with the original version - so it’s an either-or affair.

Sheep provides three banks of waveforms laid out in a 2D grid, with continuous interpolation between waves - think of it as the director’s cut (or dub version?) of Braids’ WMAP. The filter/wavefolder control is still available, for further filtering or distorting the sound of the raw waveforms. And obviously, you won’t need a VCA because of the LEVEL CV input!

Differences with the original firmware

A. The mode switch is used to cycle through the 3 banks of waves. Green: additive harmonics (no phasing effect, little aliasing). Off: PWMish (that one can alias a bit more). Red: waves from Braids’ WMAP mode. Sheep does not provide any single cycle modes. Are sheep and wavetable oscillators an Agambenian form-of-life, caught, like the benedictine monk, in the cyclicity engendered by the rule?

E. F. The SHAPE/SLOPE knobs and CV inputs control the X and Y coordinates in the wave map.

9. By default, the CLOCK trigger input cycles through the 3 banks of waves. Hold the range selector button (B) until the range LED blinks to use it for synchronization/PLL just like in Tides’ original firmware (Check the Clocked/PLL mode section of the manual).

10. The HIGH TIDE output contains a low-fidelity (1-bit) version of the signal. Crrbrbrbshshsh!

11. The LOW TIDE output contains a -1 octave square sub oscillator.

12. The UNI and BI outputs contain the same signal, but UNI oscillates between 0V and 8V ; and BI between -5V and +5V.
