DR-OM is a virtual synthesizer that simulates the hackable yard sale treasure of the same name. Dozens of DR-OM units have been adapted from a rare, limited science lab function generator that started turning up in flea markets in the 70s. DIY synth enthusiasts discovered the device was easily hackable, and closely-guarded photocopies of modding schematics have been handed around the community for years. The directions show how to rewire the generator into a nice little synth with two mixable Low Frequency Oscillators and a Voltage-Controlled Filter. This app is a complete and playable simulation of three different versions of DR-OM boxen that were discovered at a yard sale near Quonset Point along with a folder of photocopied schematics. Each DR-OM unit has its own characteristic sound because of degrading components or bad wiring by the owner. The Speed dial is the most finicky part of the assembly; depending on the box, the dial can cause tuning drifts, random events and gnarly effects. In the seventies, the noise generator was nicknamed "Doctor Om" for the meditation-friendly tones it generates. Others believe the name is an acronym for Drone Ready Oscillator Module or Dual Recirculating Oscillator Module, but no one knows for certain where the name comes from originally. Notes for iPad users: 1. You'll probably want to use more than 2 fingers with DR-OM, so try turning off Multitasking Gestures in the General Settings on your iPad. 2. Please check to make sure your side switch is "off" or in your General Settings disable the "Mute" function for the side switch. If your side switch is "on" and set to "Mute," your volume controls will be disabled and DR-OM will not be able to make sound. This is a universal app for iPhone 4+ and the iPad. It is produced by the Fluxama Group, purveyors of fine simulated synths like Noisemusick. Sound and video samples may be found on the support web site.

During a routine mining expedition in the outer regions of the galaxy five mysterious boxes of unknown origin were found. Rumours among the workers spread quickly that there was a strange feeling being around these boxes, as if time flows in a different way, not just forward but sometimes also folding back on itself. The miners nicknamed them, the five boxes of reverberation. After the excavation process, to study them more closely, it was decided to transport them back to earth. Rymdigare is part reverb, part noise and drone machine, part quality degrader and part wave shaper. The reverb is built from 5 reverberation boxes where you can control the sound with length and ratio parameters, tail and weight skew parameters and an internal feedback parameter, that could be used to create swelling tails. There is also a built in octave shifter, resonant filter, speed and level degrader and 4 LFO sources for modulating a selected set of parameters, including the LFO speeds themselves. The app can run stand-alone, connecting to other apps through Inter App Audio or AudioBus or it can run as an AUv3 plugin. Map and control any parameter with MIDI using Core MIDI, Bluetooth MIDI, Inter App Audio MIDI or AUv3 MIDI. + Resonant filter (low, band or high pass) + Noise and drone machine + Level and speed degrader + Wave shaper (input and output gain) + Reverb (length, ratio, skew, tail, feedback and type: free, bpm, tuned) + Reverb random variation controls + Octave shifter up and down + Planet orbits (LFO: double tap on parameter controls to map) + Inter App Audio, AudioBus and AUv3 + Map Midi CC using Core MIDI, Bluetooth MIDI, IAA Midi or AUv3 MIDI.
