The Roland TR-8S External Inputs allow you to plug in any Audio Source, like a Synth or another Drum Machine, and process the Input Signal using the Delay, Reverb and Sidechain FX of the TR-8S.
Sidechain is an effect that uses one signal to act on another signal. A common example of this being Sidechain Compression, in which the Sidechain Input of a Compressor on one Track receives a signal from another track, for example, the Bass Drum Track. Every time the Bass Drum hits, the compression is applied to the sound being compressed. This effect is often used in Electronic music to cause a Chord Pad or Bass Sound to duck when the Kick hits.
To achieve this kind of effect, plug the Audio Outputs of a Synth into the External Inputs of the TR-8S. Try playing a Pad or Bass Sound with a long sustain on your Synth.
