About This File
Here is a demo of the sound you are downloading.... https://soundcloud.com/bradmz/ukulele-strumming-demo-casio-px-5s
UKULE2.ZLT is a hex layer tone.
UKULELST.ZAR is an arpeggio pattern.
Load these two files into your MZ-X500. Select the new Ukulele tone as Upper 1 tone. Enable the arpeggiator and select the new Ukulele arpeggio pattern. The hex layer tone will have the muted strum sound in the lower octave, while the rest of the keyboard will be for open strumming. To play the pattern, use a rhythmic back and forth between your sustain pedal and the muted strum in the left hand while holding chords with your right hand for the arpeggiator to use. Release the sustain pedal and play the muted sound almost simultaneously. To play the strum manually as in the second part of my demo, disable the arpeggiator and practice playing chords in a sweeping motion as if you are strumming with a flat pick on guitar strings.
