NoteMapper is a powerful VST plugin designed to transform MIDI notes into other MIDI notes or control messages such as Continuous Controller (CC), Channel Aftertouch, or Poly Aftertouch. This capability enables musicians and producers to extend their MIDI setups by converting single notes into multiple outputs across different MIDI channels, enhancing creative possibilities in live performances and studio productions.

Each incoming MIDI note can be mapped to up to three different notes or messages, allowing for complex triggering scenarios such as playing drum sounds on multiple samplers simultaneously. The plugin also offers control over note velocity, including scaling, randomization, and adjustable note probability, which introduce dynamic variations to the performance. These features are especially useful for adding expressiveness when working with instruments that respond to velocity or aftertouch.

NoteMapper is ideal for converting MIDI notes between various drum kits or using a keyboard to control synthesizers through CC or aftertouch messages. Its ability to filter unwanted notes and automatically assign melodic scales further streamlines MIDI routing and performance customization. Available as freeware for Windows, NoteMapper provides a flexible and creative solution to expand MIDI functionality without additional hardware.
