STANDARD STRETCH TUNING FILES
The SC-5000 II comes with 8 non-erasable, unmodifiable stretch profiles. These “piano” stretches vary steadily in order from
very minimal (CNGD—Concert Grand) to extreme (SPNT—Spinet).

A table describing all included stretches is presented below. The piano scale length numbers are given as a rough guide for
selecting appropriate tables and refer to the dimensions normally associated with this measurement. Specifically, the vertical
pianos are measured from the floor to the highest point on the piano. The grand pianos are measured from the keyslip (the
piece of wood in front of the keys) to the furthest point back on the piano.

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.
Although they cannot be edited directly, one may copy any of these permanent stretches into a custom stretch file which can
then be viewed or edited further on a note-by-note basis. The SC-5000 II 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.
