Monaural Piano Programs; Stretch Tuning - Kurzweil K2600 Musician’s Reference

Monaural Piano Programs

Most of the piano programs are set to play in stereo, though 773 MonoStudioGrand, as well as a
number of programs on the accessory disk are designed for mono use. If the pianos are to be
played through a mono sound system, the best results will come from these mono programs, not
the stereo programs mixed to mono.

Stretch Tuning

Unless otherwise noted, piano programs are ÒstretchÓ tuned, like an acoustic piano. Since the
higher harmonics of a stretched string tend to be sharper than those of the real harmonic series,
stretch tuning ensures that the piano remains in tune with itself harmonically. Stretch tuning is
sometimes referred to as ÒsoloÓ or ÒbeatÓ tuning.
Keymaps with 440 as part of their nameÑlike 776 Mono Piano 440Ñoffer straight (non-stretch)
tuning, where the fundamental of each note is tuned to A440. Programs that use these keymaps
(for example 780 Ballad Piano) will mix better with other acoustic and electronic instruments.
This type of tuning, therefore, is sometimes known as ÒensembleÓ tuning.
