Unify's built-in MIDI Monitor plug-in is a simple utility that helps troubleshoot MIDI issues by displaying MIDI activity. It's easiest to use in an Instrument slot, but can be used anywhere in Unify, as it passes MIDI messages through unchanged.
To understand MIDI data flow in Unify, see How Unify processes MIDI data.
MIDI Monitor can be inserted or swapped into any plug-in slot in Unify.
MIDI Monitor was originally designed for use as an instrument plug-in. Click on the “ops button” (concentric circles icon) in any INST layer's instrument box, and choose “Swap: All Instruments > Built-in” and select “MIDI Monitor” from the menu.
This provides a quick way to check on the MIDI stream that would be seen by an actual instrument plug-in in that slot, but because it doesn't produce any sound, does not allow you to correlate MIDI messages you see to sounds you hear.
Since the addition of MIDI-effect slots on INST channels in Unify v1.x, you will often find it more useful to add an instance of MIDI Monitor to the MIDI-effect chain on an INST layer. Click the brown add effect icon (plus sign in a circle), choose “Add > All Effects > Built-in” and select “MIDI Monitor”.
You can also put MIDI Monitor instance(s) into MIDI layers, and drag it around to see how various other MIDI plug-ins affect the MIDI data stream.
Unify does route MIDI to some audio-effects (see How Unify processes MIDI data). If you want to put an instance of MIDI Monitor into an audio-effect slot, you can do so, but because it's considered an “instrument” it won't appear in the “All Effects” menus. You will thus have to add it to one of your audio-effect plug-in subsets, as described below.
If you find yourself using MIDI Monitor a lot, you may want to add it to one or more of your personal plug-in subsets. See Defining subsets for quick access to your favorite plug-ins.
MIDI Monitor's user interface is divided into a fixed-height Filtering area at the top, and an adjustable display area below. The entire window is resizable by dragging the lower-right corner or edges, to make more space for the display area.
The display area lists MIDI events as they are received, one per line. Each event is displayed with
The Clear button at the top right clears the display area, and also (starting in Unify v1.3.x) resets the time relative to which MIDI event-times are displayed.
The MIDI Ch pop-up menu lets you select whether MIDI Monitor shows incoming messages on all MIDI channels, or only one selected channel.
The four check-boxes in the Filtering area allow you to specify whether or not certain types of MIDI events will appear in the display:
A full explanation of MIDI messaging is outside the scope of this manual page. See e.g.
