Version 1.5 of the Korg Z1 Editor 2004 program can be downloaded here for a free 28 day evaluation. This is the latest version of the program. It includes Bulk Import, Auto Send (Sound Show) and Super Find tools and has added slider controls.

NOTE: The 28 day free evaluation should be available, even if you have an earlier version of the program (1.4.154 or 1.5.184). However, you should uninstall that version first. This will ensure that the latest help files and other files are installed correctly. If you see any "items could not be removed" messages, these can be ignored.

You can also download the author's Korg Z1 patch library. This contains 772 Korg Z1 patch files sorted by oscillator type and then alphabetically using the 2004 program. The library includes patches created by the author and other Z1 users, as well as selected patches downloaded from non-commercial Korg Z1 sites and the Korg factory presets.
