• Upgraded plugin menus : easier way to browse/automate parameters.
• Added 3 band equalizer and soft mode option in Sytrus.

Fixes:

• Small bugfix in event editor zoom/select.
• Small bugfix in effect preset selector.
• Bugfix in Sytrus (was unstable).
• Little glitch fix in Sytrus.
• Changed scale for harmonics level editing in Sytrus.
• Fixed problem with some ZIP files not created (really this time).
• Small bugfix in automation recording.
• Fixed arp/slide last bugs (I hope).
• Fixed tiny visual glitch in browser.
• Notes in step seq now restricted to the channel's keyzone.
• Added repeat mode to arpeggiator.
• Sytrus presets are now compressed (was needed for the VSTi version).
