Description

Ֆ is an adaptive audiovisual performance setup where visuals are triggered on a note-to-note basis and does not rely on any pre-rendered video files.

Ֆ consists of a Pure Data patch that generates motion graphics when it receives MIDI messages from Renoise's pattern sequencer. Each time a note is played in Renoise's pattern sequencer it outputs a MIDI message to Pure Data which then triggers a visual event through GEM's rendering engine.

Visuals are generated entirely within Pure Data with the exception of 8 PNG files which are automatically loaded in the "crank" subpatches when the main patch is launched.

Also, even if there's a specific Renoise project file intended to be played with this patch, visuals could be triggered by any other DAW, MIDI sequencer or even by a MIDI file read directly in Pure Data.

This is my first project involving visual programming and comments/suggestions are very welcome.

Using the patch

1. MIDI setup (OS X only):

This is specific to Apple OS X, however, the setup should be pretty much the same on every OS. The important thing is to create a virtual MIDI interface between Renoise (or any other DAW you'd like to use) and Pure Data. You may need a third-party software to do this (I heard http://jackaudio.org is quite nice).
