mididelay vs MIDIPlex
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
mididelay
This app applies traditional delay effects to MIDI data, allowing for complex sound manipulation. It offers multiple independent delay lines, various MIDI message processing, and customizable feedback chains with built-in effects. Organize lines sequentially or in parallel for unique sonic textures.
- 8 independent delay lines with feedback
- Processes MIDI notes, CC, aftertouch, pressure, pitch bend
- Customizable feedback modes (average, min, max)
- Sequential and parallel delay line algorithms
- Scale quantize, pitch, and velocity randomization
- 3 independent scenes with cross-fading
- Standalone and AUv3 support

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
