Future Retro XS - Manual (Page 56)

STRANGE BEATS
Here’s one way to mangle your beats. If your drum machine has stereo outputs, route one channel to the AUDIO IN jack, and the other to the GATE IN jack. In this way
the audio is also triggering the envelope generators. But you need to make sure the output of the drum machine is loud enough to trigger the envelopes in the XS. As an
alternative, you could connect the FILTER OUT jack directly to your mixer, or you could use MIDI notes to trigger the envelopes as well. But to do so you would first
need to remove the cable connected to the GATE IN jack. Adjust the filter cutoff frequency to suit your taste. And experiment with different Envelope 1 time settings.
