Single analog filter. LPF, BPF and HPF modes, analog distortion with Drive and analog positive and negative feedback.
Please see the LD3, Tiny LD, Anamono X, Xmini user manuals on details how to install this.
After installation, you must set it up in the menu's, in order to make it work properly.
On Anamono X go to "More..>Common>Filter Settings", and set either filter 1 or 2 to: 1-Most Filters, depending on in which filter slot you installed it.
On LD3, Tiny LD, Xmini go to "Edit>More...>VCF Type", and set the filter to: 1-Most Filters.
SPECIAL NOTE REGARDING VCF9:
To get most out of VCF9, you must go to the VCF page "P_2", and set the "Peaks" parameter to "Sepa" (the highest position). If you don't do this, the setting of the Cut parameter will affect the distortion Drive setting, which might create unwanted distortion on VCF output 1. Also, when Out1/2 is turned fully down, and you are only listening to VCF output 1, turning up the Peaks (Drive) parameter, might create digital clipping of the filter.
Parameters:
Cut: Filter cutoff frequency.
Peaks: Acts as distortion Drive.
Reso: Filter resonance.
Cut3/Feed: Negative values: Negative analog feedback, positive values: Positive analog feedback.
LPF: Switches the filter low pass output on or off.
BPF: Switches the filter band pass output on or off.
HPF: Switches the filter high pass output on or off.
Out1/2: Turns up the analog distortion effect on the filter output 2.
