 +=====DrumGizmo=====
 +An open source drum machine.
 +
 +====What does it do? (currently - What WILL it do)====
 +It takes input from either a midi source, or audio input, and turns these into internal trigger signals, used to activate one or more samples on one or more output channels.\\
 +Output can be jack channels, or wav files.\\
 +All inputs are controlled using velocity.\\
 +The entire system is preprogrammed using an xml file, and a **lot** of wav files. No magic file formats or obscure predefined file names.\\
 +An easy to use editor is supplied running on Qt4, which can also be used as a control interface for the drum kit.
 +
 +====Try it out====
 +Fetch MIDI files here: http://rock.mididb.com/metallica/ \\
 +Use jack-smf-utils to play back the midi files onto the jack transport. Get it here: http://pin.if.uz.zgora.pl/~trasz/jack-smf-utils/
