Resonant Filter

VCF with LFO and EG

Freq Cut-off frequency
Rez Resonance
Output Level trim
Env->VCF Positive or negative (squelchy!) Envelope modulation of cut-off frequency
Attack  
Release (use fast attack and release for "dirty" modulation)
LFO->VCF LFO modulation of cut-off frequency (turn to left for sample & hold LFO, right for sine)
LFO Rate LFO modulation speed
Trigger Envelope trigger level (normally set to minimum to acts as a free-running envelope follower)
Max Freq Limit maximum cut-off frequency for a mellower sound (the filter can sound "screechy" at high frequencies)
