Rainbow is a software synthesizer for Microsoft Windows, that can be used either as a
VST 2.0 plugin, or as a standalone application. Thanks to an original mixture of FM, AM,
additive and substractive synthesis techniques, Rainbow is able to produce a wide
assortment of sounds, from analog emulations or synthesized drums to 80's electric pianos
and synth basses. The new 2.0 version includes a 16 steps sequencer, a bandpass filter,
a 'double' mode filter (adding 2 filters in series), improved performance, and many other
additions.
