malletKAT Pro/Grand/Express Upgrades

Bring new life to your old instrument

Do you have an older malletKAT? Consider a chip upgrade!

Current Version: 6.1 (7.1 [KS])

Software Version 7.1KS of the malletKAT contains features that are exclusive to the Kurzweil Sound Card contained in the malletKAT 7KS and the GIGKAT.

A complete list of software features for this version appears on the malletKAT Features page.

Chip Upgrades are simple and easy to perform without the need to ship your instrument. See what you have been missing!

Want to upgrade to Kurzweil Sounds?

We don't blame you! Here are two alternatives to adding our newest KS sounds to your older instrument:

The 7KS Upgrade

Ship your instrument back to Alternate Mode for the ultimate retro-fitting:
  • Software chip upgrade to 7KS.
  • Preamp, volume controls, and ¼" stereo audio in and out added.
  • Kurzweil KS internal sound card installed.
  • Complete factory testing
IMPORTANT NOTE: The new KS sound card and amp board requires a LARGER power supply.  You can no longer use your old malletKAT 500mA or 1.5 mA adapter.  We will be supplying you with a new power adapter.

Purchase a GIGKAT sound module, and we will ship you the 7KS software chip for FREE. Your malletKAT User Kits will automatically display the names of the sounds - as if the sounds were built into the unit.
