Z-Maestro Anyone?

I've released the beta 2 of my main project, Z-Maestro. I hope people will find it useful. Basically, it is a music composition program similar to Apple Garageband or Acid Pro. I hope that it is easier to use than Acid Pro and that it will eventually have more features than Garageband. Right now, it works mainly with MIDI. I have split MIDI functionality into two parts: instrument and drum. There is also an audio ability where you can import WAV files and use them along with the MIDI stuff, but right now it doesn't do much. Eventually, it will have advanced audio editing capabilities such as being able to time-warp the audio, converting of audio into MIDI data, and more. Right now, you can export the instrument and drum tracks to a MIDI file, which works quite nicely. Once I finally get audio perfected, I'd like to move it away from MIDI into realtime audio instruments using something similar to SoundFonts. Then, you could apply audio effects and filters on instrument and drum data. It is a ways away from that right now, but I don't think it will be too many versions away.
