Monitor Object
The monitor Object displays all MIDI events passing through it, and retains the last 32
such events. You will need to resize it to see more than 5 events at a time.
To create a monitor Object, select New > Monitor. The monitor shows all events (MIDI
and meta) passing through it. It remembers the last 32 events, with the newest events
shown at the bottom of the list. You can resize it to show from 1 to 32 events. (You can
make it even bigger, if desired).
Monitors are very handy as both testing, and branching devices. When coupled with
Objects that have functionally different outputs (the channel splitter and mapped
instrument, for example), monitor Objects can be used to attach more than one output
cable to the same function.
Click in the body of the monitor to clear it.
Channel Splitter Object
The channel splitter routes MIDI events by channel. It offers an output for each of the
16 MIDI channels, and an additional “SUM” output. If a particular channel output is not
connected to anything, events for that channel will appear at the SUM output.
To create a new channel splitter Object, select New > Channel Splitter. You can use the
channel splitter to reroute MIDI events to different cables, in accordance with their MIDI
channels. Every MIDI event received at the channel splitter input is automatically
routed to the output that corresponds to its MIDI channel. If no cable is connected to
the corresponding output channel, the event is rerouted to the SUM output (at the
top). The SUM output is used for the events of channels with no individual output
connections.
