"Peer"-technology refers to the capability of controlling plugin parameters from other plugins, as pioneered by BTDSys' contributions to Jeskola Buzz. Armstrong and thus Buze offers a native replacement for Buzz' peers: Internally termed "controller plugins", with data passed via "event connections".
The most basic controller plugin is the Value Generator. While simple, it has a lot of power:
Note that the Value Generator is not used for notes. Instead, the Note Generator plugin is more suitable.
To use this: Create a controller plugin, connect it to another plugin and click on the connection triangle to open a dialog to select parameter bindings. In the dialog, press Enter to accept, or Esc to cancel.
