Left expander Bohm:Performer blends dual kick engines with external stereo input, offering precise side-chain ducking, intuitive one-touch DJ effects (filters, beat/slip rolls), and full CV assignability—empowering live performers with seamless, dynamic mix control. One-Touch Performance Effects FX - Selects and controls DJ-style processing—LP/HP filters, beat rolls, slip rolls—synced to your kick hits. Routes effects to the kick only, the external input only, or both simultaneously. ON/OFF - Toggles your chosen effect in perfect sync with each kick trigger. Mix & Side-chain IN - Feeds external stereo audio into the module for integrated processing with your kicks. VOL - Balances the level of your dual kick voices against the incoming audio. DUCK - Adjusts sidechain compression depth, letting your kicks cut through the mix.
