Technics Keyboard .lsw file
At any particular moment you will have various Sounds, a Rhythm, Synchro start button, Intro button, Effects and other parameters selected on your instrument.
These are known as the 'Current Panel' and are collectively saved in the .lsw file.
So, you can consider this file to be a snapshot of all the buttons and values that you have selected at the time the .lsw files is saved.
Tip: On a related subject, remember to use the CUSTOM PANEL button to save your favourite overall setup of the instrument.
This CUSTOM PANEL is similar to a PANEL MEMORY but it doesn't get overwritten when you load files, so it will always retain your favourite setup.
