Detailed Description

The Recorder element is designed for quick recording of other elements.

TODO: Support starting/stopping recording/playback on beat/measure boundaries, rather than immediately when the command is pressed.

Note:

The API methods for this element do not take effect immediately. As JackFX performs all of it's processing in a separate thread, meaning that the command may seem delayed. The delay may vary on your system, depending on the latency of the Jack server, but it should never be more than a fraction of a second.
