After Later Audio - Fuse

Fuse from After Later Audio is an exact replica of Mutable Instruments' creative audio-combiner Warps.

Fuse mixes and combines two audio signals through a variety of cross-modulation algorithms - some that emulate classic analog circuitry and others that are purely digital. Most of the sonic transformations distinguish between a carrier and a modulator signal: the former is filtered or modulated to preserve some of the latter's characteristics. Fuse also includes an audio oscillator that can replace the external carrier signal.

The cross-modulated sound can be shaped by means of control voltages in four levels: by controlling the amplitude as well as the distortion/waveshaping of the input signal, by soft scanning through the different modulation algorithms, and finally by setting a timbre parameter that controls the brightness/harshness of the modulated signal.

• The carrier and modulator each provide audio input, level control and a level CV input.
• Seven algorithms are available, which can be toggled with the large knob and via CV, and whose timbre is controlled manually or via CV with TIMBRE:
• Crossfader: Timbre crossfades between carrier and modulator signal with constant volume.
• Crossfolding: carrier and modulator are summed and some cross-modulation is added. The result is processed by a wavefolder whose strength is adjusted with Timbre.
• digital diode ring modulator: carrier and modulator are ring-modulated raw. Timbre controls the level and simulates diode distortion.
• digital ring modulator, which works cleaner than the previous one and simulates an analog ring mod. Timbre controls the level and adds soft clipping.
• XOR modulation: both signals are converted to integral 16bit values, which are connected via XOR logic. Timbre determines which bits are linked.
• Comparator and rectifier: negative signal parts of the carrier are replaced by those of the modulator, on the other hand, the absolute values of the signals are read out differently. Timbre morphs through these signals.
• Three vocoder algorithms with 20 bands that differ in the release time of the envelope follower: from short releases to freezing the spectrum. Timbre determines which bands of the analysis section are linked to those of the synthesis section and how.

Instead of a second VCO, you can also use the internal digital oscillator, whose frequency is voltage controllable and which offers various waveforms and noise. The signal of the internal VCO is available at the AUX output.

Fuse is an exact replica of Warps and can also run all its firmwares.
