Classic off-beat ducking/pumping is straightforward with the nABC+: plug the instruments you want to compress to the LINE input and trigger compression using the audio kick from a drum machine, a microphone to your acoustic kick drum, a MIDI signal from your DAW or an analog gate from your analog sequencer, whichever suits your setup! Fine tune all the audio parameters of your compression on the panel and store your presets. 

Things get extra interesting when you start to use the nABC+ in creative ways: create trance gates and programmable vibrato by triggering sidechain with a sequencer, apply different compression levels to different beats, create dynamic saturation by combining the in-built analog preamplifiers before and after the compressor stage, sidechain an effects return channel with a long reverb or delay, combine “classic” and sidechain compression within a single nABC+.. possibilities are uncountable!
