The \u003cstrong\u003ehard sync\u003c\/strong\u003e function allows the subordinate oscillator to be synchronized to the cycle of the other, generating aggressive and harmonically complex timbres.

In addition to the classic warm and musical analog behavior, it integrates a \u003cstrong\u003ebass compensation\u003c\/strong\u003e function, which maintains the presence of low frequencies even when the resonance is pushed to the maximum. This allows you to \u003cstrong\u003epush the resonance to self-oscillation\u003c\/strong\u003e without sacrificing body and depth. The filter can be modulated by both internal envelopes and the LFO and Oscillator B when used in modulator mode, opening up possibilities ranging from progressive and dynamic sweeps to more extreme effects.

The \u003cstrong\u003efilter envelope\u003c\/strong\u003e shapes the cutoff over time, with attack, decay, sustain, and release that allow you to sculpt the brightness and body of the sound with precision.
