During 2012-13 City Frequencies developed a few audio apps
for release. The first release for Android is called Elevator 17 and documents the 2006 Fringe Festival tour with a live performance recorded from inside the 17th elevator we visited. Photos from the build and subsequent tour phase are included as a slide show. The second release is a synth module called IMS5 that has an 8-step sequencer, octave multiplier, saw oscillator, basic ADSR controls, filter/delay/phaser controls and interface types of sliders, buttons and some XY trackpads.
