Midi Thru 2.1 offers you a useful MP3 tool which allows you to connect a controller synth to a slave synth. Midi Thru allows you to slave up to six synths, sending on the midi channels of your choice.
It's great for those times when you don't want to fire up a major memory eating sequencing program to use as a midi thru or when you want to write lyrics in your word processor and don't have enough memory left to fire up your memory hogging midi sequencer or if you just want to jam on those favorite synth modules.
It's also good for layering up to six synths. It's a simple program that does one thing and one thing well. It's a Midi Thru !

Dent du Midi 0.9
Converts MIDI to AIFF for use with GarageBand. more>>
These AIFF container files are suitable for dropping into Apples GarageBand application for use as loops or entire tracks. In simple terms, this application allows you to convert MIDI files into GarageBand files.
The name is a bit of a play on words. Dent du Midi is a 10,686 foot (3257 meter) mountain in the southwest of Switzerland in the west Alps.
The name is French and is pronounced something like "don doo midi" which I thought sounded like "dont do MIDI" which is why I thought it would be an appropriate name since GarageBand doesnt import MIDI files.

This saves wear and tear on the Kurzweil buttons and it allows you to work more efficiently. Take the simplest task on your Kurzweil. You've just created a new program, or layed down the first track in a sequence.
The Kurzweil wants a name for this new object, and you sit there for 5 minutes spinning the data wheel or pecking at the keypad to enter "Rad Piano" or "Techno Song". Forget it! Now just reach over to your Mac keyboard and type on a normal keyboard! And that's just the start. The Companion allows you to see your Kurzweil screen remotely, allows you to enter numeric data for things like frequencies, select programs from a complete, searchable list instead of 8 crowded lines, export the list of objects in your machine, and more.
Requirements:
- Mac OS X 10.3 or later, and a two-way MIDI connection between your Mac and your Kurzweil.
