GM-4 General MIDI Module
The GM-4 is a 16-channel, multi-timbral GM sound player with 128 patches and a GM standard drum and percussion kit.
To select a channel for patch assignment or editing, click one of the 16 channel meters.
Channels 1-3 are muted by default to allow the other instruments in the Key Rig to play without interference from the GM Module. It is also useful
to use the other three instruments of the key rig at times to replace GM instruments with "better" sounds in a GM arrangement.
M: GM channel mute for the selected channel.
S: GM channel solo for the selected channel.
Category: all GM standard patches are arranged into the GM standard categories. Clicking this field produces a drop-down menu of all
categories.
Note: Although selecting a new category will also change the display of the instrument control (see below), a new sound will not be loaded until
it is selected from the instrument control
Instrument: clicking this field produces a drop-down menu of all patches within a category for selection.
Chorus: applies a standard GM chorus to the selected channel.
Reverb: applies a standard GM reverb to the selected channel. This reverb is a send to the Master FX section of the Key Rig, allowing you to set
any kind of effect and control the amount of all channels independently. It's important to note that if the MFX is set to an effect other than the
default reverb, the GM-4 reverb effect will not be a standard GM reverb.
Volume: sets the volume for the channel selected.
Pan: controls the pan position for the selected channel.
Tone: the General MIDI tone control, which adjusts the brightness of the patch.
