Notes and suggestions
Waveform Not all Waveforms cover the entire extension of the keyboard. This becomes
particularly evident when you use an 88 note master keyboard on which you can reach the
extremes of the extension.
The problem is due to a lack of samples at the extremes of the keyboard. During the creating
phase of a Waveform, considerations are made for the quality of the sound and the amount
of memory necessary to store all the samples which consitute the Waveform; if some high or
low end samples are lacking in musical quality (e.g., the lower notes of a violin Waveform,
or the higher notes of a doublebass Waveform), it is preferable to eliminate them to avoid
using up precious memory.
Volume, Dynamic & Aftertouch The Volume of a Sound can be controlled in live
situations by dynamics and aftertouch variations (programming in the Volume editor). If
you set very sensitive values for both controls (e.g. +7 assigned to both dynamics and
aftertouch) the Sound will be very difficult to control and easily susceptible to sudden
volume variations.
Loop and Lfo By programming a loop on two segments of a Key On Envelope which
create an ascending and descending ramp (
) you can simulate a Tremolo effect, without
using the Lfo editor.
A loop of this kind on a Key On Pitch Envelope will simulate a more realistic Vibrato effect
than the effect obtained with the Lfo.
Key Off Envelope Thanks to the greatly articulated Key Off Envelope (Release envelope)
of the S Series, you can create some very interesting effects. In practice, you can render a
Sound “live” after releasing the keys.
For example, try programming a Key Off Envelope of the following kind with a Sound such
as 12_St_Gtr:
When you release the key the sound begins to fade and then reappears, it is held for an
instant and then fades away gradually.
Lfo Lfo can be applied to several different sound parameters. The effect produced depends
on the parameter affected:
Amplitude –> Vibrato
Pitch –> Tremolo
Cutoff Freq. –> Wha-wha
Filters The action of the filters on the sound is represented by curves:
Hz
dB
Low Pass (attenuates the high end frequencies)
Hz
dB
High Pass (attenuates the low end frequencies)
Hz

Band Pass (attenuates the frequencies above and below the C.F.)
