Zacchino

I'm really happy about that one. Especially because a lot of users lost their faith about this product line. Now might be the time to give it a second try :

-New high-performance Multi-threaded Audio Engine
-DualCore Processor support
-Multitrack Audio & Midi Recording (incl. STEP RECORDING, Punch in/out, loop, etc.)
-Multiple Media files per tracks
-Groove Cloning
-Automatic Crossfades
-Inline MIDI Editing
-Midi Filtering & Processing
-VSTi Parameters automation (and "on the fly" enveloppe drawing)
-Drum Map Editing
-Project Sections (Re-arranging projects)
-Control Surface Support (via MCU)
-Realtime Input Monitoring
