I use Composer to produce and/or edit MIDI sequences of Hymn Tunes to play in church. I save them to a floppy which slots into my Yamaha keyboard so all I have to do in the service is select the file, press go and stop and adjust the volume.

This all works very well indeed and has added a lot to our services as we previously had to sing un-accompanied. However, the keyboard is quite a large device to lug about every week so I am wondering if anyone knows of a device that just contains a floppy drive, LCD, control panel and, of course, a MIDI synthesiser. That ought to fit into something the size of a lunch box which could then be connected to our amplification system just as I now connect my Yamaha. Any ideas?
