The reason I announce this release of Scala, a program to explore musical tunings, is that the Linux version finally works with MIDI now. It uses the OSS devices, but I have only tested it with ALSA. If you want to use an ALSA softsynth, you can connect it via a virtual MIDI device. http://www.xs4all.nl/~huygensf/software/scala-20-pc-linux.tar.bz2 Scala is also very useful as a virtual keyboard, one that can be used with any tuning. After setting the device with Edit->Sound Settings, press F4, select a notation system, click "Scale preset" and play. There are several dialogs that can play, most in the Analyse menu. You might like to try the Tonality diamond, Triad player, Tone circle, etc. The View->List of Chords dialog can play any predefined chord. Any volunteers for porting Scala to OS X on this list? I hope ALSA will support the MIDI Tuning Standard for soundcard synthesizers sometime. Then we can have much better accuracy. Manuel
