SF2 is a complete softsynth, sampler, live improvisation tool, and studio soundfile processing application. This latest release has been completely rewritten to provide many new features and native Mac OS X support.
What's new in this version:
New features include improved support for audio hardware (seperate devices for input and output can now be run at the same time. multichannel devices are now handled properly), individual sample playlist volumes, saveable playlists, saveable patches, ADSR envelope editors, modulation portamento, scramble waveform, recording clock, and interface enhancements. SF 2.1 is a free upgrade for existing 2.0 license holders.
