Mac
Up to eight Audio Unit instruments, each on its own MIDI keyboard – no DAW. Ten instant setups, and one button records your jam as a mix, separate tracks and MIDI.
BH AU Host turns your computer into a multi-instrument for live playing – no DAW, no projects, no tracks. Load up to eight Audio Unit instruments, give each one its own MIDI keyboard and channel, and play.
• Up to eight Audio Unit instruments at once
• Each with its own MIDI input (a specific keyboard or all), channel or Omni
• Level, mute and hold for every instrument – leave a chord ringing and play on top
• Ten setups: plug-ins, sounds, inputs and levels recalled with one click
• Play from the computer keyboard when no controller is at hand
• EXT IN: play an external instrument through your audio interface and send it notes over MIDI
• Recording sketchbook: the mix, a track for each instrument and MIDI for each instrument – all lined up to the sample, ready for any DAW
• Opens each instrument's own window with its full interface
• Choose the audio output and buffer size for the latency you need
• English and Polish, with a built-in user guide
Try first: BH AU Host Light is free – one instrument, the same sound engine.
About plug-ins: BH AU Host 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 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.
