mda RezFilter simulates a VCF (voltage controlled filter) with LFO and EG (envelope generator). With both Attack and Release times set very fast, it can provide “dirty” modulation.
|Env→VCF||Positive or negative (squelchy!) Envelope modulation of cutoff frequency|
|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)|
