General Music WK4 Owner's Manual page 150

Files loaded into the WK4 memory are converted
to WK4 Songs.
GMX format
GMX refers to the "General MIDI eXtended" for-
mat, specifically created by Generalmusic, which
renders the first three sound banks of the WK4
with previous series instruments (WK and PS)
completely compatible.
To program WK4 Songs that are perfectly com-
patible with all WK and PS Series instruments
(e.g. WK4 and WK3), use the Sounds of the first
three Sound banks and record the Songs using
16 tracks only (MIDI channels A1...A16).
TRACK STATUS ICONS
