Models
-
2hp LFO
United States
The 2hp LFO is a voltage-controlled low-frequency oscillator offering eight waveforms with smooth morphing between them for complex modulation shapes. Its range spans from a thirty-second cycle up to audio rate. It provides two simultaneous outputs and a reset input for syncing to a clock.
-
2hp VCO
United States
The 2hp VCO is an analog voltage-controlled oscillator built around the reissued Curtis CEM3340 chip. It outputs triangle, sawtooth, and square waveforms simultaneously, with pulse-width modulation, linear FM, and hard sync. Accurate 1V/octave tracking across more than ten octaves suits both melodies and dramatic pitch sweeps.
-
2hp Euclid
United States
The 2hp Euclid is a rhythmic pattern generator based on the Euclidean algorithm, which spreads a chosen number of active steps as evenly as possible across a sequence. It produces repeating rhythmic patterns useful across many electronic music styles and offers voltage control over the pattern generation.
-
2hp ADSR
United States
The 2hp ADSR is a four-stage linear envelope generator with two selectable ranges. Its attack, decay, sustain, and release stages can each be adjusted independently to build simple or complex multi-segment envelopes. It is well suited to shaping filters, VCAs, and oscillators.
-
2hp TM
United States
The 2hp TM is a probabilistic random sequence generator inspired by the work of Alan Turing. Controls for randomness, sequence length, and output range let it act as a controlled random voltage source or, paired with a quantizer, an evolving melodic sequencer. Adjusting probability and length lets it produce a practically endless variety of patterns.
-
2hp Mix
United States
The 2hp Mix is a four-channel mixer for audio or control-voltage signals. Each of the four inputs has its own level control, and they are summed into a single output. It is DC-coupled, so it handles both audible signals and modulation with a low noise floor.
