Crumar Spirit - Sound Creation Techniques

NOW ... TO TUNE THE SPIRIT ...
BEFORE TUNING ALWAYS CHECK TO SEE THAT THE PITCH BEND
WHEEL IS CENTERED.
9. Depress the key you want to match and tune using the TUNE control in
the MASTER section. You may want to select a brighter sound for
tuning; to do so, use the OSCILLATOR A WAVEFORM switch.
10 . Push FILTER/ADSR slider B (next to A) up.
11. Use
the OSCILLATOR B INTERVALcontrol to produce beatfree tuning
between Band A. (Note: Osc B is presently one octave lower that A.
Change OCTAVE/RANGE to UNISON to match pitches.) Once again,
you may want to I isten to a brighter waveform; to do so, change the
WAVEFORM switch for Oscillator B.
When
you start from the Preparatory Pattern it is easy to get a sound:
switch VCA to BYPASS and raise the A slider. When tuning, tune A first
using the MASTER TUNE control, then tune B relative to A using the
I NTERVAL control and OCTAVE/RANGE switch .
For best signal- to - noise ratio, place MASTER VOLUME high (at least 5).
use
reasonalby high slider positions (at least 6). and adjust your amplifier
loudness to a comfortable listening level.
SOUND CHARTS
THIS SECTION SHOWS YOU HOW TO CREATE SOUNDS EASILY
BY DUPLICATING SOUND CHART SETTINGS ON THE CONTROL
PANEL OF THE SPI RIT, AND HELPS YOU LEARN THROUGH
EXPERIMENTATION.
Unlike the traditional arranger, who chooses from a group of instruments
with somewhat fixed characteristics, the synthesist is confronted by a
continuous spectrum of instrumental and non-instrumental sound textures.
Because the sounds of the synthesizer are not as fixed and well-known as
many other instruments, we have developed a notation system that shows
what the front panel of the instrument looks like when a particular sound is
produced - - the sound chart. A sound chart is only an approximation. To
get the most from these sound charts several ideas may be helpful:
