I own a TX81Z, which I use primarily with my
QXl. Is there any way of accessing the Perfor-
mance patches via MIDI Program Changes?
It
seems that Program Changes only call up the
Internal and ROM Voice patches.
The TX8IZ's MIDI Program Change param-
eter has three basic settings-Off, Common,
and Individual-which determine how the unit
will respond to Program Change messages:
Off: The TX81Z ignores MIDI Program
Change messages.
Common: The TX8IZ looks up the correspond-
ing Voice Number or Performance Number
in its Program Change memory, and reacts
accordingly.
Individual: The TX8IZ's "instruments" receive
Program Changes separately (over the as-
signed MIDI channels), and each looks up
its Voice Number from the Program Change
Table. If the Table entry is a Performance
Number, it is ignored.
The TX81Z's internal memory contains 4
banks of 32 permanent (ROM) Voice memo-
ries, I bank of 32 programmable (RAM) Voice
memories, and I bank of 24 programmable
(RAM) Performance memories. In the Program
Change Table, these memory locations appear
as follows:
Memory Bank
RAM: Voice Bank I (1-32)
ROM: Voice Bank A (1-32)
ROM: Voice Bank B (1-32)
ROM: Voice Bank C (1-32)
ROM: Voice Bank D (1-32)
RAM: Performances (1-24)

When shipped from the factory, the
TX8IZ's Program Change parameter is set to
"Common," and the factory defined Program
Change Table assigns the available Program
Change numbers (1-128) as follows:
Program Change

1-32

In order to call up Performance memories
using MIDI Program Change messages, you

need to program the TX81Z's Program Change
Table accordingly. The most straightforward
approach involves setting the TX81Z to
respond to MIDI Program Change numbers 1-
24 by calling up Performances 1-24. To do so,
follow these steps:
1) Press the Utility button.
2) Press the left and right Parameter keys until
the LCD reads as follows:
UTILITY MODE
Midi Control?
3) Press the
+
I /YES button to access the
MIDI parameters.
4) Press the ~ight Parameter key (12 times) un-
til the LCD reads:
UT MIDI CONTROL
Edit P.Cng Tbl?
5) Press the
+
1/YES button. The LCD will
now read:
UT MIDI CONTROL
PGM 1 I01
6) Press and hold the
+
1 I INC button until the
LCD reads as follows:
UT MIDI CONTROL
PGM 1
=
PF01
7) Press the right parameter button. The LCD
will now read:
UT MIDI CONTROL
PGM 2 I01
8) Press and hold the
+
1/INC button until the
LCD reads as follows:
UT MIDI CONTROL
PGM 2
=
PF02
Continue the above process until you have
assigned PF01-PF24 (the TX8IZ's Performance
memories) to Program Change numbers I-24 in
the unit's Program Change Table. These Table
settings are stored as part of the TX81Z's System
Setup memory, and will be retained in the unit
even when the power is turned off.
