Update the hardware (e.g. new sound card, new memory - etc) so you can purchase and use with your existing AUDYA product? Not sure that will be realized .....
When new hardware is required, manufacturers simply use it in a new keyboard.
Having said that, KETRON is one of the very few companies that actually does offer a real hardware upgrade to older products (such as the USB Card Reader and Audio Player) that replaces the old floppy drive in older KETRON instruments (X-series, SD-series, XD-series ... etc) and provides the capability to now use modern USB sticks and SD cards AND playback Audio (wave and Mp3) and MIDI in those products!
The software will be a great plus to AUDYA users.
Thanks,
