StreamByter is a powerful plugin designed for creating customized MIDI effects, available as an Apple Audio Unit (AU) effect or a standalone application that connects through CoreMIDI virtual ports. Originally developed from the MidiFire MIDI processing environment, it allows musicians and producers to extend the capabilities of their MIDI setup with advanced control and manipulation options.

This plugin enhances MIDI workflows by enabling users to remap channels, notes, and controllers, filter MIDI events with precision, and apply effects such as cloning or delaying events. StreamByter also supports sending specific MIDI events automatically upon loading, which streamlines performance setups and automation. Its programming-based approach incorporates conditionals, loops, variables, and mathematical operators, allowing users to build sophisticated MIDI processing routines tailored to their needs.

Configuration is handled through a textual rules language that defines how MIDI data is manipulated, offering deep customization without requiring extensive technical knowledge. For optimal routing with CoreMIDI, pairing StreamByter with a MIDI routing app enhances functionality. Built on the MidiBus library, it provides a reliable and flexible platform for advanced MIDI processing, making it a valuable tool for anyone looking to expand their MIDI creative possibilities.
