Hi Dale, > we need software that'll take MIDI in & out and be able to print sheet > music. (Must be compatible w/ PDF writer, too, since we're hoping to sell > the curriculum & music after we use it.) Using a 300MHz iBook for MIDI myself, I can try to give you some hints... although I must say that actually with that iBook I'm using exactly those costly packages you would like to stay away from! (Cubase 5 VST, Steinberg Midex 3,... :-) Assuming that you use Mac OS 9 (or 8) with your iBook, in order to contain costs my advice would be getting some second hand software like MicroLogic Fun or Steinberg Cubasis VST. The former was even free with an English magazine I've subscribed to (MacFormat, issue 86, January 2000). Another option is Metro SE, which should cost you less than $70, and which is both Mac OS 9 and X compatible (just do a search at www.versiontracker.com), although I'm not sure whether it features score editing or not. A shareware option I remember of is Virtual Composer, which relies heavily on QuickTime - I don't remember if it can be used with an external MIDI interface, though. A further but very basic shareware option is MIDIGraphy ($20). An awesome but discontinued Opcode pro MIDI/audio package, Studio Vision Pro, is available for purchasing here: <http://www.opcode.com/HowToGetSW.shtml>. For just $99.95, it's truly a bargain... although it lacks score editing, if I remember well. Finally, I heard beautiful things about the ease of use of the oddly named sequencer MbooM, which that alone would cost you around $100 though. By the way, I've just tried to reach its home page (www.mboom.com), but it's currently down... which is not a good sign. Then you could pick some second hand USB MIDI interface like the Steinberg USB 2 MIDI - as far as USB MIDI interfaces are concerned, there are several choices, and frankly, for your purposes, any USB MIDI interface would suffice. Just search eBay, you'll find plenty of offers. By the way, several small keyboards and synthesizers come with a "to host" port for plugging them directly to USB ports (and thus becaming themselves an external MIDI interface for your Mac), so if you happen to own one of these (or plan to get one), you don't need any other external MIDI interface. This said, I have to add that I'm definitely not an expert about "cheap" MIDI packages, so if anyone else has other suggestions, please post your contributions :-) Roberto Giannotta Trieste, Italy
