mididelay is an implementation of traditional delay effect adapted for the MIDI data. It features: • 8 independent delay lines with feedback • Each delay line can process MIDI notes, control change, aftertouch, polyphonic key pressure and pitch bend messages. • For the feedback, the “feedback level” is applied to the messages; note messages change velocity and all other messages can be mixed with previous values using one of three modes (average, minimum and maximum value) • It’s possible to organise delay lines in different possible ‘algorithms’, sequentially and/or in parallel • There are three effects available inside delay’s feedback chain: scale quantise, pitch and velocity value operations randomisation • Each ‘preset’ contains 3 independent scenes marked “A”,”B” and “C”, it’s possible to cross- fade between them and adjust overall amount of the effect with 2D pad. • Simple mode : only one delay with scenes morphing. Standalone and AUv3
