Agent Grey is a moody, suspense-driven preset for COBALT5S.

Oscillator 1 delivers a pulsing, sub-heavy bass tone, while oscillator 2 adds an eerie, siren-like quality that wobbles in pitch—creating constant tension and uncertainty.

Apply Aftertouch to gradually open the filter cutoff and reveal hidden details.
Or drag your finger up on the trackpad to let oscillator 2 rise in pitch, pushing the tension even further.

This preset is built around a tempo-synced LFO and performs best in the 140–170 BPM range.

Enjoy.
