Medleyan® is a software product that provides a collection of built-in MIDI data processors, which are called Tools.
One or more of the included Tools are hosted in a resizable virtual container called the Rack, and can be arranged in any order. Incoming MIDI data stream is passed into each Tool in the Rack sequentially from left to right.
The output of each Tool feeds the input of the next Tool in the Rack, and so on until the accumulated MIDI output is passed back to the DAW or otherwise sent to the intended destination.
You can add as many individual Tools (and as many of each) as you like to the Rack (subject to available system resources), and arrange them in whatever order makes sense for the situation. Want to see what’s going on with your MIDI stream at various points in a Rack-load of Tools? Go ahead and add a couple of Monitor Tools to the Program, and let them show you!
Medleyan® is currently offered as a Standalone App and Audio Unit v3 MIDI Effect plugin for iPad.
