External Instruments and Effects
You can integrate external effect devices and external instruments, for example, hardware synthesizers, into the sequencer signal flow.
Requirements
To use external effects, you need audio hardware with multiple inputs and outputs.
An external effect requires at least one input and one output or input/output pairs for stereo effects in addition to the input/output ports that you use for recording and monitoring.
To use external instruments, a MIDI interface must be connected to your computer.
Audio hardware with low-latency drivers.
Nuendo compensates for the input/output latency and ensures that the audio that is processed through external effects is not shifted in time.
