490-ST
NAME FULL NAME DESCRIPTION
CNGD CONCERT GRAND Useful for all concert style grand pianos of approximately 8 feet in
length or greater. This minimal stretch profile may also be of use on
smaller pianos strung with thin piano wire or in situations where the
user wishes a greater coherence of fundamental pitch throughout the
instrument.
STGD STUDIO GRAND Optimal for a 6’ to 7’11” range of grand piano.
AVRG AVERAGE (all classes) Taken from optimal settings for vertical and grand pianos of many
makes and sizes, this profile will produce a reasonable tuning for
non-critical applications. It also provides a good starting point for
creating your own stretch profiles.
SMGD SMALL GRAND Useful for grand pianos that are 5’10” or smaller in scale.
UPRT UPRIGHT Suitable for vertical pianos equal or exceeding 51”.
VERT VERTICAL Taken from optimal settings for many makes and sizes of vertical
pianos, this profile will produce good results for any vertical-style
piano in typical playing environments for such pianos.
CNSL CONSOLE Designed for vertical pianos in 39” to 51” range.
SPNT SPINET Designed for vertical pianos smaller than 39”, this profile is the most
extreme (farthest bass and treble note stretching) of these piano
preset stretches.
G5TH GUITAR 5THs
OCT0: E(low string), A
OCT1: D, G, B
OCT2: E
A unique tuning adjustment for standard-tuned guitars (or,
additionally, for “1/2-step down” tuning: E=, A=, D=, G=, B=, E=
as well as simple open chord tunings) in which “power-chord” 4ths
and 5ths are optimized. This is very useful in situation where
distortion is to be used as part of the guitar tone. (This “stretch”
avoids a compromise of the P5TH temperament under the
Temperament presets through the ability of stretch files to have
independent adjustments for each “E” string.)
Although they cannot be edited directly, one may copy any of these permanent stretches (with the exception of the G5TH
stretch) into a custom stretch which can then be viewed or edited further on a note-by-note basis. The Model 490-ST permits
up to 31 user-programmable stretches which can be created in this way or “from scratch”.
The actual note offset values for each of the piano presets is presented in Appendix C at the back of this document.
The FILE (temperament or stretch) menus are accessed under the SETUP screen. Thus, the first step when starting from the
normal RUN screen is to press the “1” button to enter SETUP:
