Basic Digital Operation
Arbitrary (ARB) Waveform File Headers
Storing Header Information for a Dual ARB Player Waveform Sequence
When you create a waveform sequence (described on
), the PSG automatically creates a
default file header, which takes priority over the headers for the waveform segments that compose
the waveform sequence. During a waveform sequence playback, the waveform segment headers are
ignored (except to verify that all required options are installed). When you store the waveform
sequence, its file header is stored with it.
Modifying and Viewing Header Information in the Dual ARB Player
Once a modulation format is turned off, the waveform file is available only to the dual ARB player.
This is also true for downloaded waveform files. Because of this, future edits to a waveform’s header
information must be performed using the dual ARB player.
To modify header information in the dual ARB player, the waveform file must be playing in the dual
ARB player (although you can view the header information in the dual ARB player without playing
the file)
You can reapply saved header settings by reselecting the waveform file for playback. When you do
this, the values from the Saved Header Settings column are applied to the PSG.
Modifying Header Information
All of the same header characteristics shown in
Modifying Header Information in a Modulation
are valid in the dual ARB player. This task guides you through selecting a waveform file and
accessing the header for the selected file, then refers you back to the aforementioned procedure to
perform the modifications.
1.
Select a waveform:
a.
Press
Mode
>
Dual ARB
>
Select Waveform
.
b.
Using the arrow keys, highlight the desired waveform file.
c.
Press the
Select Waveform
softkey.
2.
Play the waveform: Press
ARB Off On
to On.
3.
Access the header: Press
ARB Setup
>
Header Utilities
.
4.
“Modifying Header Information in a Modulation Format”
to edit the header information:
•
For a default header, read the information in step one on
, then perform the
remaining steps in the procedure.
•
To modify an existing file header, start with step three on
.
The rest of this section focuses on the additional file header operations found in the dual ARB
player.
