Amos is a reactive MIDI instrument. It sends MIDI notes to your software synths, outboard gear and desktop DAWs like GarageBand, ProTools and Live. Amos supports CoreMIDI (USB and WiFi), DSMI, and the IK Multimedia’s iRig MIDI.

Here's a video of Amos in action: http://www.youtube.com/watch?v=RqYj3NCQ1gQ

In Amos's physics-simulated room, collisions between objects trigger MIDI notes. Up to five duration discs (whole note, half note, quarter note, eighth note, sixteenth note) can be grabbed and thrown around the room. There are two 6-octave keyboards that can be configured via the Settings menu. When a disc strikes a keyboard key, it takes on that key‘s note value and emits that value for each collision until a new key is struck. Tilting the device controls the gravity in the room.

Anaphobia Mini (short: AnaMini) is a monophonic virtual analog synthesizer for iOS 5.0. It features a classical analog synthesizer setup using a VCO, LFO, VCA and VCF. Of course, none of it is really controlled by voltage, but rather by a 32-bit digital synthesis engine.

Features

• One oscillator with two wave types and scalable within the range of -1 and +1 octave.
• Two LFO's with fixed wave type (saw) and selectable frequency/rate and depth. One LFO modulates VCO frequency, the other VCF cutoff.
• One VCA with fixed ADSR envelope.
• One 24dB/octave VCF with three filter types and selectable cutoff frequency and resonance.
• A one-octave keyboard with support for portamento and legato play.
• 14 factory presets.
• 20 custom presets.
