MIDI Operation
The 300 provides two dtterent methods for using MIDI Program Change
messages.Thesefunctionsare accessed in Control mode(selected by pressing
Using MIDI Program
CONTROL). From Control mode, use the PAGE UP/DOWN keys to select the
c.taDg8 t,,8ss8gr,s
MIDI Control page and press the key directly beneath “EDIT”.
With t,,8 So0
MIDI Table mode has three selections: OFF, FIX and MAP.
MIDI Table mode
OFF sets the 300 to ignore all incoming Program Change messages.
if you are in the FIX mode, andare frmsmiffir~gon me Sysfemcbame/, Program
Change messages 0-99 will select 300 Setup Presets Pl-PIOO; Program
Change messages 100-127 will select the first 28 Setup Registers (RlR28).
Note that R29-R50 are nofaccessible to the MIDI Program Change mechanism.
Setup changes will take precedence over Effect changes.
In FIX mode, if you are transmitting on channels assigned to Machine A and B
&f;c!~ afe diffefenf from fhe Sysfern chatme/ number, Setup changes will be
ignored. For each Machine, Program Change messages 0-99 will select Effect
Presets Pl-PlOO: Program Change messages 100-127 will select Effeti Reg-
isters Ri -R28. On/y effecfs which are /ega/ for fbe sefup G//be se/ecfed. Illegal
effects will be ignored (the currently running effect will not change.) An error
message will be displayed.
You will quickly discover that a fixed relationship between MIDI Program
Changes and the 300’s preset and register numbers is not very convenient.
Changing the presets in a synth, or the registers in the 300, is not all that easy
when you have to arrange everything so that MIDI Program Changes have the
desired effect. To solve this problem, the 300 has a corresponding map table
which is used when the MIDI Table mode is set to MAP. In this mode, program
changes are transmitted on the Sysfem channel you have assigned. Setups,
effects for Machine A and effectsfor Machine Bean be mapped to any program
change message. Dealing with MIDI Program Changes becomes much easier
since you can completely rearrange the relationship of MIDI Program Change
numbers to the 300’s registers and presets in minutes.
To assign Program Change messages to presets or setup registers, call up the
Editing the MIDI Table
MIDI Control page (from Control mode), and press the button directly below
‘“EDIT”,
PreSS either the first or second button on the top line, and use the Soft knob to
SdSCt the MIDI Program Change number you want to use. The third button on
the top line allows you to select S (Setup), EA (Effect A) or EB (Effect B). The
rightmost button allows Soft knob selection of the setup or effect preset or
register number you want loaded by the Program Change number displayed on
the top line. Continue this procedure until the table contains all of the entries you
need.
