The two main filter slots are identical and feature multiple modes including emulations of classic synth filters.
Each filter slot may be stereo-panned separately.
The SEM, Matrix-12, Mini, and Jup-8.
There are also special filters native to Pigments, such as the Surgeon.
Each filter slot offers the same ten choices.
Yes, this varies depending on the type of filter selected.
For example, the SEM is continuously state-variable with a knob (which can be a modulation target).
The MultiMode filter, on the other hand, offers 14 combinations of state (lowpass, highpass, etc.) and rolloff slope (12dB, 24dB, etc.).
This quick menu lets you copy the settings of one filter to the other, or swap the positions of the two.
This can subtly or dramatically change the sound when the filters are routed in series.
Not only that, but you can continuously morph between series and parallel routing.
The menu below the knob that does this also lets you route the sum of both filters to both effects busses,
or send each filter to a separate FX bus.
It controls the amount of filter FM.
You can modulate each filter from any of the ten sources in the drop-down menu below it,
without using the central modulation source strip.
KBD, for example, is traditional keyboard tracking.
Extreme results are possible using different sources at higher amounts.
This is actually part of the VCA section.
You can modulate the overall Preset level using any of the 24 sources offered in the drop-down menu.
The knob governs the modulation amount.
This knob controls the initial stereo position of the overall Preset when a MIDI note-on message is received.
This may change, of course, if other pan parameters (such as the filter pans or things on the FX tab) are being modulated.
Voice Pan is simply the starting place.
It determines the level at which any active voices are passed to the Send FX Bus.
It is duplicated on the FX tab — the two knobs control the same parameter.
