The author's instructions
2. Quick Start
Please prepare MIDI data in Standard MIDI File Format 0.
From DOS prompt, enter:
LXMIDI -N1 -X -O8 -C120 SAMPLE.MID (normal machine)
or
LXMIDI -N1 -X SAMPLE.MID (double speed machine)
(SAMPLE.MID is assumed to be the name of your MIDI file). Now
our 100/200LX is reborn as a palmtop MIDI sound module.
If you are a user of a normal speed machine, you will notice
the high pitch noise. Reducing the value of the '-C' option
may improve the sound. First reduce the value to a point
where you encounter a skipping sound, then increase the value
by 3 to 5.
If you want to play the MIDI date in formats other than SMF
Format 0, please refer to Section 5 below.
Your should have at least 130 KB of the conventional memory
(or 70 KB, if EMS is available) to run LXMIDI. If your sound
data are larger, you need more. If enough memory is not
available, LXMIDI will terminate during reading from the file.
Specifying '-S' option, when more than 4 pages of EMS is
available, will use EMS and thus enables the playback of
larger data.
From Ver 1.70, LXMIDI can create and play music data in
Object File format (extension .LXM), an internal data format
of LXMIDI. Running LXMIDI with '-W' will create the LXM data
file. Although larger in file size in most cases, it can be
loaded faster and enables to start the music immediately.
