0015-GigaPiano-II Pedal Down Dynamic Resonance (2ch-1p)
Here we have the actual sustain pedal resonance from the GigaPiano II. In the past, we
had to have a complete set of “Pedal Down” samples recorded at several velocities to
emulate this important characteristic of a piano. Simply sustaining pedal up samples is
not very realistic. On the actual piano, there is real reverberation and string resonance
happening that creates the lush sound we are used to. However, sampling the pedal
down notes doubles the size of the library (on the hard drive and in RAM) This method
also does not allow you to apply sustain ambience to notes played before pressing
the sustain pedal as you can on a real piano. On the real piano, you can actually hit
some notes with the pedal up, then press the pedal and hear some of the soundboard
resonance applied to those notes. This is not doable with simple samples of the pedal
down resonance. However, by turning the actual resonance into an impulse model, we
can do this accurately and use only half the samples.
In the GigaPulse, the Sustain pedal has been assigned to instantly turn the input and
mic levels on and off, allowing the piano samples to be run through the actual pedal
down resonance.

You can adjust the lushness of the pedal ambience with the wet/dry mix setting.
