About

JAX SR

This audio effect processor allows selective frequency range processing for modulation effects. It offers a classic chorus with MIDI control and aims to avoid negative side effects by targeting specific frequency bands.

Highlights
  • Selective frequency range processing
  • Classic chorus modulation
  • Optional direct MIDI control
  • Universal app for multiple Apple platforms
  • Avoids negative side effects of full-range effects

The manual is available at : https://audio.digitster.com/wp-content/uploads/2024/05/JAX-SR-Chorus-Manual.pdf The JAX SR Series are AudioUnits (AUv3), which allow to select a frequency range for effect processing. This one provides a classic chorus modulation effect with optional direct MIDI control assignment to the parameters. If (especially) modulation effects are applied to the entire frequency range, this usually will introduce negative side effects. The JAX [SR] Series allow a selective frequency range and dynamic adjustment of the mix easily. More information can be found on the product website at: https://audio.digitster.com/ Please note, that AudioUnits (AUv3) require a supporting host application to perform. This build (like all our latest releases) is truly 'universal', meaning, the audio unit is available for: - MacOS (Apple Silicon) - iOS (all actual iPhones) - iPadOS (all actual iPads) - visionOS (Apple Vision Pro) Requirements: MacOS 10.15++ iOS 14.0++

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
