AZR3-JACK is a port of the free VST plugin AZR-3.
It is a tonewheel organ with drawbars, distortion
and rotating speakers. The original was written by
Rumpelrausch Täips. The organ has three sections,
two polyphonic with 9 drawbars each and one
monophonic bass section with 5 drawbars. The two
polyphonic sections respond to events on MIDI
channel 1 and 2, and an optional keyboard split
function makes the bass section listen to the
lower keys on channel 1. The three sections have
separate sustain and percussion switches as well
as separate volume controls, and the two
polyphonic sections have separate vibrato
settings. All three sections are mixed and sent
through the distortion effect and the rotating
speakers simulator, where the modulation wheel can
be used to switch between fast and slow rotation,
and the fast and slow rotation speeds themselves
can be changed separately for the lower and upper
frequencies.
