BH AU Host Light
Play Audio Unit instruments
Only for Mac
Free
Mac
Load an Audio Unit instrument, plug in a MIDI keyboard and play – no DAW needed. Simple, free, and sandboxed for safety.
BH AU Host Light is the simplest way to play your Audio Unit instruments without a DAW. Pick an instrument, pick your MIDI keyboard, pick where the sound should go – and play.
• One Audio Unit instrument, one controller keyboard, a few settings
• Choose the MIDI input (or all inputs) and channel: Omni or 1–16
• Choose the audio output and buffer size for the latency you need
• Level slider with a live meter
• Opens the instrument's own window with its full interface
• Remembers your instrument and its sound
• English and Polish, with a built-in user guide
About plug-ins: BH AU Host Light runs in the macOS App Sandbox. Many instruments work right away. Some plug-ins are loaded in a separate process; for the first of them macOS may ask once about "Lower Security Settings". After you confirm, further plug-ins load without asking.
BH AU Host Light collects no data. Your audio never leaves your computer.
Part of the BH series of small, practical music tools by Bronisław Hońca – on the other side.
