CrazyRhythm is a MIDI controller designed to create complex rhythms and the second plugin of the 'Crazy' series. It allows you to create custom rhythms using note lengths, ratios, time signatures, a programmable rhythm and measures section. It also has MIDI output for all 5 channels so another VST plugin, such as a drum synth, can be controlled with it.
Rhythms can also be saved and loaded as custom .crhythm files.

The concept: a different approach.
The plugins of the 'Crazy' series are based on a different approach to measures and rhythms, in particular poly-rhythms. Instead of using predefined note lengths to create a time signature the plugins use tempo ratios between the different notes. The base tempo used is your DAW project tempo.

Example:
A ratio of 1 against 2 at 120BPM would make a time signature of 120BPM against 240BPM, in other words: the notes that have a ratio of 2 are played twice as fast as the notes that have a ratio of 1.
In the "old way" this would be a time signature of 1/2 or 2/4, etc.

Okay, but what is the difference?
By using tempo ratios instead of note lengths you can essentially set the note lengths to anything. What about a ratio of PI against the square-root of 2? Or any other decimal number? By using ratios we can create time signatures and poly-rhythms that would otherwise be very hard to create through conventional means.
