Master FX – A Real-Time Effects Processor For iPad

master-fxiMusicAlbum has released Master FX – a multipurpose effect processor for iPad.

Master FX is intended for real-time processing of sound from one or two external instruments or microphones separately while playing or singing. It can also mix instrument sound or voice with pre-recorded audio tracks. Master FX can also be used as a sound processor within a variety of other musical applications as it supports Audiobus.
