© 2015 by K. Meiere -

This utility reads MKS-50, Alpha Juno-1 and Alpha Juno-2 Bulk Dump *.SYX files from your computer's hard drive and displays all of the Tone names on screen. Click the button below to load a valid MKS-50, Alpha Juno-1 or Alpha Juno-2 Bulk Dump file. You may then copy the names from the screen and paste them into a text file or a spreadsheet. This can be useful for identifying specific sets to help organize your sound library.
