This plugin is a modification of the Master Pitch plugin requested by a Reddit user, to have different transposition groups. The plugin sends MIDI transpose information when it is set to Sender mode, and receives it when it is set to Receiver mode.
Transpose information is sent / received between plugins that have the same ID. A maximum of 64 IDs can be set, allowing to have 64 different transpose groups.
Every time a plugin is set to Receive, it receives the transpose information automatically. But when the ID of a plugin set in Sender is changed, the transpose information is not sent until the controls are changed or the RESEND button is pressed.
The colors of the plugin automatically change to match the color theme of Live.
This plugin is free. Clicking on the download button will open the Gumroad window. You can enter $ 0 as the price to download it. Consider making a contribution if it is useful for you.
