Surge XT's Delay supports independent L/R times, crossfeed, and LFO modulation for stereo widening

Surge XT’s stereo delay has independent left and right delay times (both tempo-syncable), with the right time optionally linkable to the left. Feedback controls self-feedback per channel; Crossfeed feeds signal from each channel to the other, creating ping-pong and other stereo bounce patterns. Low/High-cut EQ on the delayed signal allows filtering repeats progressively darker or brighter. A modulation LFO (triangle wave) can detune the delay lines by up to 200 cents — at subtle levels this creates stereo widening and chorusing; at high levels, pitch-bending echoes. Channel panning routes left and right inputs to the delay units before they combine.

Examples

Set left delay to 3/8 note, right to 1/4 note, Crossfeed at -12 dB for a musical ping-pong pattern. Add 5-cent LFO modulation depth for slight stereo width on repeats.

Assessment

What is the timbral effect of enabling Crossfeed vs. leaving it off? How does adding 200-cent LFO modulation depth change the character of the delay from a standard echo?
