Hi James,
Glad to hear you love your TimeFactor!
There is currently no Eventide Stompbox Preset managing software but check Eventide.com often for updates.
For now we recommend two freeware applications for backing up and restoring presets on your Eventide Stompbox:
For Mac: SysEX Librarian (see http://www.snoize.com/SysExLibrarian/ )
For PC: MIDI-OX (see http://www.midiox.com/ )
With these software apps you can store individual Preset sysex files when dumped from the Eventide Stompbox using the "CURRENT" MIDI Dump option from the Stompbox's System menu. You can store hundreds of single-preset sysex files in a folder on your computer and audition them by dumping them back into the Stompbox from one of these software apps.
