This allows you to use the same channel for 2 parts, so that you hear a layer of 2
instruments playing the same part.
Send General MIDI Mode ON sets the external module to General MIDI
mode. This command will ensure that the module is ready to accept GM-
specific MIDI data such as Bank, Controller, and Patch information.
Send GS mode On Message (Roland) / Send XG Mode On (Yamaha): Since
the inception of the GM (General MIDI) standard, there have been two major
subsets/extensions of this standard - GS (Roland) and XG (Yamaha). Therefore,
in addition to the GM Mode-on menu item feature there are additional
commands to send a GS mode ON or a XG mode ON message at any time by
accessing the GS menu.
Master Volume type allows you to set whether to use “Roland GS Sysex
Messages” or “Yamaha General MIDI messages” for Master Volume controls.
Unless you have a Roland Sound Canvas synth or the Roland VSC, you should
select the Yamaha type.
Auto-Send GM mode at start sends a “General MIDI mode on” message when
the program boots up.
Auto-Send GS mode at start sends a Roland GS system on message when the
Band-in-a-Box program boots up.
Auto-Send XG mode at start sends a Yamaha XG system on message when
the Band-in-a-Box program boots up.
Use MIDI messages instead of GS / XG Sysex should be set by all users
except if you have a Roland GS synth (i.e., Roland Sound Canvas) or Roland
VSC. If set, the Combo settings will allow Master Volume etc to work.
