DB50XG Overview and Features
■
Element Reserve
The DB50XG has an Element Reserve feature that lets you
reserve a specified number of notes for certain Parts, in
order to keep notes from being “stolen” from those Parts
by other Parts if incoming MIDI Note data exceeds maxi-
mum available polyphony.
For example, if you specify an Element Reserve value of
“10” for Part 1, then Part 1 will always keep 10 elements
for itself. You can set Element Reserve values with MIDI
System Exclusive messages (see XG Native Parameter
Change on page 11, and <Table 1 - 4> on page 28).
■
Selecting Voices
The DB50XG not only contains the 128 basic GM Voices
and GM drum set, but many variation Voices as well—to
give you access to a total of 676 Normal Voices and 21
Drum Voices.
In XG mode, the basic 128 GM Voices can be accessed by
selecting Program numbers 1 – 128. Other Voices can be
accessed by selecting both bank numbers and Program
Change numbers. The Voice bank can be selected via MIDI
Control Change Bank Select (MSB and LSB) messages.
In XG mode, the MSB value determines the Voice type
(Normal, Drum), while the LSB value actually selects the
bank (excluding the SFX bank).
When the DB50XG is in TG300B mode, the Voice banks
can be selected with appropriate MSB numbers, as LSB is
fixed.
Lists of all available Voices along with bank and program
numbers are provided on pages 32 – 37.
Note that the 128 MIDI Program Change numbers consist
of 0 through 127, whereas the 128 DB50XG program num-
bers consist of 1 through 128. Depending on the sequenc-
ing hardware and software you use, you may have to con-
vert the DB50XG program numbers to the appropriate Pro-
gram Change numbers.

Change messages, see About MIDI, page 6.

Effect Types
The DB50XG features dozens of extremely versatile digi-
tal effects generated by Yamaha’s advanced Digital Signal
Processing (DSP) technology—which add a completely
new dimension to your computer’s sound.
There are three distinct effect types, or effect sections, each
of which include a variety of individual effects. There are
11 Reverb type effects, 11 Chorus type effects, and 42 Varia-
tion type effects. For a complete list of effects, see the Ef-
fect Type List on page 38.
Reverb, Chorus and Variation effect types are configured,
or routed, in one of two ways—to be either a System Ef-
fect or an Insertion Effect. The difference is as follows:
• SYSTEM EFFECT
- Applies the designated effect to all 16 Parts.
• INSERTION EFFECT
- Applies the designated effect to only one specific Part.
Reverb and Chorus effect types are dedicated System Ef-
fects, and therefore are applied to the overall “mix”. The
Variation effect type, however, can be configured as either
a System Effect or an Insertion Effect. To designate effect
types and parameter values via MIDI messages, see XG
Native Parameter Change, page 11.
