Fiddlewax Pro was just released last month, but already it has had its third update in as many weeks!
What's new in Fiddlewax Pro v2.0:
Directly record audio to create custom instruments. Import SoundFont files (.sf2) to use with instruments. Import audio files (.m4a, .wav, .mp3, etc.) as samples. Adjust sample parameters (gain, offset, attack, & release). Updated Audiobus and added remote play/pause. Improved circular loop indication. Updated user interface and simplified info overlay. Expert MIDI mode (adjust volume of each channel). Muted chord automation for advanced users. Minor bug fixes.
