Cautions and other functions in Sequencer mode
M3 sequencer file formats
The M3 sequencer supports both the proprietary M3
Song format, and Standard MIDI Files.
If you like, you can convert data between the two
formats, simply by loading the data in one format and
then saving it in the other.
For details, please see “Save to Standard MIDI File” on
page 411 of the Parameter Guide, and “Save SEQ” on
page 410 of the Parameter Guide.
M3 Song format
This is the native M3 sequencer format, which is
required to ensure that all M3-specific data is saved
correctly.
Standard MIDI Files
You can also load and save Standard MIDI Files (SMF),
for compatibility with other sequencers. Note that
some M3-specific data may not be maintained when in
SMF files.
GM, XG, and GS System Exclusive Data
The M3 sequencer can record System Exclusive
messages, including XG or GS data. For details, please
see “System Exclusive events supported in Sequencer
mode” on page 295 of the Parameter Guide.
Note that GM, XG, and GS exclusive messages do
not affect the M3 when they are played back.
The Compare function
When you perform realtime recording, step recording,
or track editing, this function allows you to make
before-and-after comparisons.
If you continue editing when the COMPARE switch is
lit, the switch will go dark. This now becomes the
musical data that will be selected when the COMPARE
switch is dark. Any previous unsaved edits will be lost.
Operations for which Compare is
available
In general, MIDI track and pattern event data can not
be returned to its original state.
Comparing song parameters is possible only during
song editing (when executing a menu command).

Comparing after sampling
The Compare operation will also apply to
multisamples and samples that were sampled with
Convert to
enabled in “Select Bank & Sample No.,” as
described on page 275 of the Parameter Guide. This
means that if you want to re-do your sampling, you
can press the COMPARE switch to return the
multisample and samples to the state prior to
sampling, and unwanted samples will not remain.
The program will not be affected by the Compare,
and will not return to its prior state.
