Past Release Notes

## Installation

The Mark ProTWOi receives its system updates through MIDI sys-ex (i.e. playing a specified MIDI file containing system exclusive data into its MIDI in port and/or via MIDI-over-USB). Details on how to update your Mark ProTWOi system files can be found in the MarkPro TWOi OS Update Procedure.pdf and MarkPro TWOi Boot Update Procedure.pdf (both included in this download).

Update Requirements / Recommendations

> Windows Users:
> - XP Users: to update to v1.05 via USB, simply follow the included instructions MarkPro TWOi OS Update Procedure.pdf. (No need to update the boot loader)

> (recommended for XP users) "MarkPro TWOi.inf" XP driver (available on Kurzweil's website). The installation of this driver permits your host DAW to reference the Mark ProTWOi by name versus a generic, standard driver label. Unnecessary for Vista.

Alternatively, you can also use a traditional MIDI connection/interface with your Vista (or XP) system. Follow the included installation instructions MarkPro TWOi Boot Update Procedure.pdf.
