I remember this app from when I started playing around with palm pilots and music software. It was a lot of fun, especially if you synchronised with another PDA and made a piezo duet.
I couldn’t get it to work under OS5, but with my older clie it works fine.
I plan to post on all the older OS4 software eventually, one app at a time, and, if possible with screen shots too.
I think it is worth keeping these older apps as they were the forerunners of the new music applications we’re seeing today.
