Description

Crum Hum is a 3-voice experimental and expressive soundscaping instrument designed for generative and ever-evolving melodic and harmonic creation.

The Crum Hum features 12 sound engines which range from simple sawtooth and square waves with lowpass filtering, to various wavetable and FM engines and more complex setups like bass, chords, and melody. There are also 12 different built-in scales to play with.

Each of the three voices has a triangular touchpad that lets you control the timbre and volume simultaneously. Each voice also offers a Frequency knob for setting the lowest possible note, as well as a Random knob that sets the probability of notes being played for each clock pulse.

The Tone knob affects the timbre of all three voices simultaneously. What it does exactly depends on the selected sound engine and the tone can also be randomized for subtle to drastic sonic variations at each clock pulse.

Moreover, Crum Hum features built-in delay, reverb, and overdrive effects, as well as an LFO that can modulate the frequency, tone, or volume. There’s an internal clock generator, but it’s also possible to sync the synth to an external clock source. Most parameters can be controlled via MIDI CC (see the user manual for more details).

In addition to a stereo audio output, Crum Hum features a CV output that corresponds to the touchpads, allowing for expressive control of other modular instruments.
