This patch mapper is designed specifically for the Moog Grandmother synthesizer, providing an intuitive interface that mirrors the look and feel of the original instrument. It allows users to save and load patches via MIDI CC messages, covering all parameters supported by the Grandmother's MIDI implementation. Although it does not support full program dumps through sysex, it offers comprehensive control over adjustable parameters, including envelope settings and global management features. The application supports bidirectional communication with the hardware, providing real-time visual feedback through LED ring buttons and a detailed envelope graph that can be manipulated with a mouse or rotary encoders.

The patch mapper includes a user-friendly patch browser and editor with options to rename programs, assign categories, and add detailed descriptions such as author and save date. Users can load and save individual patch files and export program parameters as text, making organization and sharing straightforward. The interface features a unique patch cable visualizer that displays up to nine colored cables connecting various inputs and outputs, including external synths, sequencers, and effects chains. This visual patching system enhances workflow and creativity by clearly illustrating signal routing with adjustable transparency and display options.

Available as standalone software and as VST/AU plugins for both PC and Mac, this patch mapper integrates smoothly into various studio setups. It supports multiple file formats for associated audio files on Mac systems and allows switching between light and dark interface themes to suit user preferences. While it does not generate sound itself, it functions as a powerful editor and patch management tool that simplifies working with the Moog Grandmother. Additional features include customizable MIDI CC numbers for certain controls, enhancing compatibility with external hardware controllers for extended performance control.
