MobMuPlat (short for Mobile Music Platform) lets you create your own custom audio software for iOS, via the open-source audio environment PureData. MobMuPlat hosts a list of user-created documents, each of which defines a user interface and audio engine. MobMuPlat can do synthesis, sampling, networking via local wifi, OSC messaging, query and set hardware characteristics, display images/graphics, and much more. see www.mobmuplat.com for more info. Creating your own work consists of two parts, both done on your laptop/desktop. First, create the audio engine using the graphical programming language Pure Data (PD) Second, either use the native PureData GUI, or create a graphical user interface (GUI) with the MobMuPlat Editor. With PureData and the MobMuPlat Editor open, and data sent between the two, you can simulate the app behavior on your laptop/desktop. Once development is complete, just drag the two saved files into the "Documents" folder of iTunes, and they are uploaded to your device and can be opened in the MobMuPlat app...

Relic Flow is a generator of Lo-Fi rhythms, noise patterns and drum loops based on unique synthesis algorithms from NightRadio. More than 4 billion samples from the depths of the Mathematical Universe! Features: * search for new sounds with three buttons: next random set, edit code, previous set; each set of 12 sounds corresponds to a code of 8 characters; * three types of keyboards for live performing: on-screen buttons, PC keyboard, MIDI input; * several processing parameters + control via MIDI; * real-time audio recording to WAV (32-bit); * export to: WAV (one file or a set), SunVox (samples + effects in one file), text clipboard; * the LCK button freezes individual samples - they will not change during the search for new sets; * iOS Audio Unit Extension (AUv3). Double clicking on a parameter opens a window for setting the exact value. If you enable the Hold option, the notes will play endlessly, without reacting to key release (noteOff) events; turning the note on again works like turning it off; there are two ways to enable this option: 1) using the Hold parameter in the "MIDI Mapping" window; 2) by pressing the HOLD button, which appears in place of LCK while playing the musical keyboard: press HOLD, release the desired notes - then the released notes will continue to play.
