Marbles' Y output is a slow smooth random source, immune to DEJA VU, ideal for self-patched modulation

The Y generator outputs a smooth, full-range (-5V to +5V) random voltage clocked by default at 1/16 the rate of X2, making it a slow random LFO (its rate is adjustable from 1/64 to 1 of X2). Unlike the X section, Y is never affected by the DEJA VU settings, so even when X is locked into a repeating loop, Y keeps wandering freely. This makes Y the natural self-patching source: routed to SPREAD, BIAS, JITTER or RATE it reshapes the core behaviour of the t and X sections over long timescales, adding slow evolution that plays against a locked pattern so the patch never sounds static.

Examples

Self-patch Y to the SPREAD CV input: with X locked (DEJA VU at 12 o’clock) the melody stays fixed in order while Y slowly widens and narrows its pitch range, so the loop breathes over time.

Assessment

Explain why Y being immune to DEJA VU is musically useful, and give two self-patch destinations for Y that produce slow evolving modulation.
