Hi Esh: I recently (last week) just received my new upgraded MusicPad Pro Plus 4.0 with its new improved hardware & memory enhancement. As I'm located fairly close (less than 40 miles away) from Freehand Systems (manufacterer of the MusicPad Pro), located in Los Altos, CA, I guess I'm among the lucky first to have had my MusicPad Pro completely swapped out for a brand new MusicPad Pro 4.0 unit. Among the new enhancement features I most appreciate is now being able to display two pages at a time in landscape mode, as well as 4.0's new song 'browse & search' feature. I have several large complete fakebooks of songs (MANY 100's of songs) in my MusicPad, each in its own folder, with perhaps different versions of the same song in multiple books. The new browse function allows me to search and call up any song title, and then see/review all the different renditions available & quickly pull up the one I want.

The only glitch I notice with MusicPad 4.0 (so far) is that to perform a search, you must pull up a "keyboard" in which to enter (with your finger on the screen), the first few letters of the song title. Strangely enough, it's not possible to verify the letters you entered, or initiate the 'search function', until you close or move the keyboard. Freehand acknowledges the bug, and promises a fix in a subsequent update.

Re: the MusicPadPro 4.0 audio output. My MusicPad Pro indeed includes a 1/8" audio out jack. I haven't had a chance to test it yet, and the manual doesn't specify whether it's mono or stereo. The MusicPad Pro's audio feature is pretty basic: play, pause, and speed up/down, and only supports midi & MP3 file playback, as well as a pitch pipe & metronome playback feature, handy for acoustic solo instrument tuning & keeping time. The audio playback feature was primarily designed for playing back their Digital Sheet Music Partner's (Sunhawk) sheet music collection, which also includes a midi file of the song as well, to assist in learning the song. I'll try to contact Freehand Systems to confirm whether the single audio output jack in mono or stereo, and get back to you.
