Just as a few suggestions:
1.Having the 3 band EQ available for MIDI files as well as the Audio files in the Players screen.
2. A "Panel Lock" function, assigned a button. This freezes all the buttons so when live, we don't accidentally launch something else whilst playing.
3.Have the user settings retained (you know velocity settings, system effects settings etc etc) when the unit is turned off.
4.The possibility of being able to create a "play list", for live gig work. That way we can set up at home, go to gig and just load up the playlist and away we go
5. Be able to drag and drop directly to the desktop, rather than just the Desktop folder in the home menu. We used to be able to do this on OS 3.x but on 4 it seems placing either files, folders, or shortcuts on the desktop itself is blocked.
6. The ability for the user to upgrade or replace Linux software. In other words allow the MS to access repositories.
Of course this is at the users risk.
7. Allow embedded artwork in MP3 files to be viewable. Sort of like mini chord charts.
Thats about it for now. But I am sure I will think of others.
Thanks for the chance to offer some suggestions Dom
