Chopper is an amplitude-based Side-Chain Compression Emulation effect with:

- BPM Control
- Selectable Internal/External BPM

- Internal Clock
- Width Control
- Depth Control
- Selectable Sync Source

- Envelope
- Attack Control
- Release Control

- Smooth Control

- I/O
- Input Gain
- Output Gain

- 4-Step Sequencer
- Selectable Step Patterns
- On Switch

- Side-Chain Input
- Selectable Side-Chain Source
- Threshold Control
- Side-Chain Input Meter
- Gain Reduction Meter

It's all the fun of side-chain compression, without the hassle of side-chain compression!

As a note: Internal BPM refers to inside the instrument, and External BPM refers to the project BPM.
