F244 Mellotron.4
Designed for use with strings, voices, flutes, and synth pads, this filter
attenuates certain lows and low mids while boosting upper midrange
frequencies to give that unnatural, tweaked Mellotron sound. All filters are
scaled for Keyboard Center C1.
Morph: Opens filter to allow the natural sample to come through
unprocessed.
Freq. Tracking: Tunes the filter.
Transform 2: Not Used.
F245 Cello
Designed for certain types of bowed string sounds. Try using Velocity to
drive Morph and/or Transform 2 axes.
Morph: Increasing values turn notches into peaks.
Freq. Tracking: Tunes the filter.
Transform 2: Increase for additional brightness.
F246 Key Squeak
Morph: At low values, contains a fairly mild low pass slope with slight
peaks at 400, 1200, 4000, 5200, 8800Hz opening to a flat repsonse
with slight peaks at 360, 1280, 4400, 5120 and 8620Hz.
Freq. Tracking: Tracks filter over five octaves of keyboard.
Transform 2: Higher values reduce filtering effect until response is flat
at 255.
F247 Pluck.4
Morph: Low Pass with steep slope and two bumps at ≈120Hz and
≈600Hz which opens to a flat response at higher values.
Freq. Tracking: Tracks filter with keyboard.
Transform 2: Not Used.
F248 Pick It
Designed for acoustic guitar. Assign the wheel to Morph (in the Note-On
Controllers) to control pick placement. Assign velocity to Transform 2 for
dynamics, and key number to Freq. Track for balance across the guitar's
range.
Morph: Controls filter Q.
Freq. Tracking: Tunes the filter.
Transform 2: Gentle lowpass - higher values open the filter.
