The Make Noise/soundhack Spectraphon is a dual Spectral Oscillator coded by Tom Erbe of soundhack. It uses real-time spectral analysis and resynthesis to create new sounds from those that already exist. It is inspired by classic electronic musical instruments of the past, including spectral processors, additive synthesis, vocoders, and resonators especially the Buchla 296 and Touché, but it takes a physical form more resembling the classic analog dual complex oscillator in the lineage of the Buchla 259 and the Make Noise DPO.

The STO music synthesizer module is a compact Voltage Controlled Oscillator designed for generating SINE waves, Variable wave-SHAPEs, SUB-Octaves, Oscillator SYNC and Linear FM in the analog domain. The Sub-Timbral Oscillator is the more subtle and melodic friend to the DPO's complex harmonic lattice.

Strega is an audio alchemical experiment. Activate! Spill the tonic into time and let time decay through the filter to hear the results. 

The X-PAN music synthesizer module is a compact and powerful 5 channel Voltage Controlled Stereo Mixer with Low Noise and High Headroom allowing for creation of complex panoramic audio imagery in just 10hp.

The XOH (miX Out Headphone) music synthesizer module is a stereo mixer, headphone amplifier and output interfacing module for your modular synthesizer.

The XPO or Stereo Prismatic Oscillator is a Voltage Controlled Analog Oscillator designed for generating Sine waves, Triangle waves, Sawtooth and Spike waves, Sub-Octaves, Stereo Timbre Modulations (including Pulse Width Modulation and Wavefolding), Oscillator SYNC, Linear FM and more in the analog domain.
