q2midi is a 'note generator' - when any gate signal is received, an algorithmic sequence set to key and rhythmic specifications is output along your MIDI chain. The q-engine is the same as employed in xoxos q-series VST instruments, now applicable to any instrument.
Two more 'layers' of randomization are 'nested' around the gate and pitch generators for creating complex patterns that repeat or transpose motifs, or don't. q2midi also includes a separate assignable CC# control in addition to gate, pitch and velocity output.
q2midi is bundled with arp2midi as a $5 bundle.
