5.4. Note Filter
There’s a lot of power hidden under the
Filter
button on the NOTE FX panel.
This note filter is new to Synclavier for the Regen product. Like the Effects Filter
it pertains to the timbre you’re currently working on and is saved with it. Unlike
the Effects Filter, which applies to all sounds on the track, it applies to each note
individually and contains a re-triggerable envelope.
Regen supports 1 Roll Off filter per partial, 1 Effect Filter per track, and 1 Note
Filter per note. That can add up to a lot of active filters. We have made the filter
algorithm as efficient as we can to
make the theoretical possible
, but there’s a limit.
If you’re using a tonne of filters, it’s always wise to check the CPU meter found
on the MASTER
Volume
page. If, while playing some chords, you go into the
red line, there’s a possibility of Regen dropping notes. Lots of filters are
certainly possible, and lots of Reverbs too, but what we’ve found is a
combination of many filters and reverbs is what can crush the CPU.
On the Note Filter page, you have the following options:
Filter Type | Filter Setup | Filter Env
As with the Effects Filter, you can select
Filter Types
of Low Pass, High Pass,
and Band Pass, with 12dB (shallow) or 24db (steep) roll off
Filter Setup
and
Filter ADR
will take you to subpages. The Filter Setup page
has options:
Pitch Track | Cut Off | Resonance
As described previously, the
Cut Off
point is the frequency at which the filter
attenuates the input amplitude by 3dB (amplitude is halved).
And the
Resonance
adds an emphasis at the
Cut Off
frequency of the filter.
As with FM Amount, a little goes a long way. Check out Starry Eyes [AM 3-2] to
see that a filter with 4% resonance is enough to add the right punch to saw wave
to make a useful popular music timbre.
Pitch Track
moves the
Cut Off
frequency depending on what MIDI key is
received. Recall that each note has its own individual filter.
Pitch Track
can be turned Off by setting the value to zero.
