modified noise toaster

This is a #noisetoaster analog synthesizer that I built for a child - designed by Ray Wilson of #mfos and based on a mod by a guy named Kurt in case you want to search that. The stackable banana plugs makes many more possibilities available to the child patcher.

read pointer hack

This is a delay line sampler instrument with two controls that affect the delay line read pointer position. The knob controls how much to increment the delay line for each sampling period. Essentially it's how many samples to play back, so you can affect the pitch and the speed of the sample. The button divides the read pointer in two, providing a momentary octave drop. This counts as an instrument because I used it at a show. The violin is mostly wood and pig intestines.

bambi decays eternally

An digital emulation of analog tape delay, with a momentary tape stop/read pointer shrink function that reads the delay at half speed, providing an octave shift. Designed to be manipulated while playing guitar with separate pedal for foot control.

big brother filtered chorus

This effect is a LFO equipped low pass filter feeding into a chorus effect. The filter resonance is tied to the delay line feedback, meaning that changing the filter shape effects the chorus density. This thing has a fun and funky energy and is really fun to jam with - just like the big brother this was built for. ❤️

tactile piano

An octave-in-14 tactile switch instrument. Switches trigger digital oscillators with a fixed attack and release. The 14 oscillators are tuned across an octave in equal divisions. That's it.

BIG BOX

This is a digital tape-style delay effect. Delay changes speed up or slow down the rate of reading the delay line, producing the pitch effects. This thing has a lot of features like tap-tempo and delay subdivisions, but I mostly use the digital tape stop! It's a momentary push button that stops the delay line and filters the incoming audio until you release the button, which also re-introduces the delay. You can mod the filter cutoff with a LDR as well.

big dumb mountain

Pitch-tracked reverb. Pitch estimation is performed on incoming audio, producing a control signal which is applied to the reverb mix. Controls include reverb volume, dry volume and low and high frequency cutoffs to determine the frequency range where the effect is applied.

horse chords

Chord-following synthesizer. Chord recognition is performed on incoming audio, which sets the tonality of notes being synthesized. Interaction with light dependent resistors triggers tones synthesized and passed through an envelope. Controls present for light detection threshold and mix of synth output and chord input volume.

centrophone

Audio feature-organized sampler. When powered on, Centrophone draws 12 random audio samples on the device. Feature analysis is computed, and the samples are mapped to the keyboard in order of ascending values of the chosen feature. Audio features supported for the ordering of samples include spectral centroid, spectral flux, and RMS energy.
