Kurzweil K150 - UPDATE V1.6 SOFTWARE Update Manual

These notes describe changes to the version 1.6 release of the K150 FS software. The major changes are:
Next/Prev and Incr/Decr button positions are reversed.
MIDI Channel and Mode are memorized. All program assignments are remembered in Multi-mode.
Seven user-editable Intonation Tables plus fourteen ROM-based tables designed by Wendy Carlos are provided.
Optional keyboard control of reference key for real-time modulations.
System Exclusive messages for loading and dumping master parameters, programs and voices (with optional
Voice RAM).
System Exclusive messages to support remote front panel control.
Button Reversal
One of the most common complaints about the K150 is the position of the INCR/DECR and NEXT/PREV buttons.
Although one thinks of them from left to right, their normal positioning on almost all electronic equipment is from
right to left. The new software reverses the position of these keys. Upgrading an existing unit requires reversal of
the key caps.
Better Multi-Mode Support
MIDI channel and mode (Omni, Poly or Multi) are memorized in the non-volatile RAM. In addition, program
assignments in Multi mode are remembered. This allows complete instrument setups to be saved across power
downs.
Expanded Intonation Features
Version 1.6 supports seven user-definable intonation tables. In addition, fourteen ROM-based intonation tables
(designed by Wendy Carlos) are provided. The names, numbers and values of these tables are given in Appendix A.
The range of tuning adjustment available via the intonation table has been expanded to a full tri-tone (i.e., ±600
cents or 1/2 octave in each direction). This allows creation of unusual scales with notes that are very close together.
A new mechanism is provided for changing the intonation reference key over MIDI. When the Auto Ref Key
switch (available in the EDIT TUNE menu) is ON, MIDI Note On messages for key numbers 0 (C) thru 11 (B) will
change the reference key. Note that in MIDI, C0 = key number 12, so 0 thru 11 are seldom used. Thus, if you have
a controller that will transmit those key numbers, you can use it to change the reference key dynamically, allowing
real-time modulation while using a non-equal tempered tuning. (Again, thanks to Wendy Carlos for this idea!)
