miniMusic has released version 1.4 of its popular <A HREF="http://www.miniMusic.com">NotePad music notation software</A> for the Palm Platform. A long list of improvements includes scrolling playback, mid-song tempo and instrument changes, expanded support for keyboard commands and the directional pad on the Treo smartphones, a new scroll bar for song navigation and a new "page view" that displays 20 measures of music on a handheld computer's screen at once. Many of the new 1.4 features improve on capabilities that NotePad already had available. You could previously assign a different instrument to each voice, so a song could use four different timbres. Now you can insert instrument changes to use as many instruments in a song as you like. You could previously watch one voice/track scroll while it played, now you can watch all of your tracks scroll by as they play together.
