About

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.

Highlights
  • 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

About

pOus

This app emulates analog drum machine bass drums with adjustable tuning and decay. It offers MIDI OUT functionality for envelope follower data and a scale mode for playing musical scales. Designed for musicians using AUv3 hosts.

Highlights
  • BassDrum emulation
  • Adjustable tune and decay
  • MIDI OUT envelope follower
  • Scale mode for musical notes
  • AUv3 instrument
  • MIDI CC routing
Read full description

Concept: The app is an AUv3 instrument that emulates the so-called “BassDrum” of analog drum machine. In addition it features MIDI OUT functionality of Envelop Follower, that is, the user can send out this instrument's unique envelop via midi CC for modulating external plugins. Also there is "scale mode" where the user can play "pOus" with musical scale like Bass. System Requirements: AUv3 host that has a flexible capability of MIDI routing (AUM, apeMatrix, etc) Usage: There are 9 sliders & one button. Tune: BassDrum’s fundamental frequency (30hz - 160hz). text-editable. Decay: determines its duration. Amp: audio’s decibel representation. MIDI OUT: whether the functionality of envelop follower is turned on or off (default: off) MIDI Gain: gain amount of MIDI out Offset: balances the output parameter’s value Channel: determines MIDI channel MIDI CC: determines the destination MIDI CC number. text-editable Scale Mode: This is a sort of Bass mode, that is, it can play musical scale in response to incoming MIDI notes. Button: triggers the instrument. Recommended Scheme: drum machine (MIDI out) -> “pOus” -> audio effect (compressor, saturator etc)

Verdict

The call

The clearest difference is update cadence: pOus at every 4 months against mididelay's every 10 months. pOus also leads on price ($2.99 vs $4.99) and iOS requirement (12.0 vs 15.6). mididelay's advantage is ratings volume (3 vs 1). On rating, ads, in-app purchases and monetization model there is nothing between them.
