Trouble with Synthesia, your keyboard, or adapter? Think you found a bug?
When describing problems, always mention your OS and game version (shown at the bottom of the title screen).
If your keyboard has USB or MIDI ports, there is a tremendously high chance (>99%) it will work with Synthesia. See what you'll need on the keyboards page.
If I go from this page to 'Feature Voting' and there I click on the link to login I get an error 'page not found' after logging in returning to the previous page (Feature Voting page). Is it something of this forum or something in my browser/cache?
Alright, I don't know what I was thinking before. An '&' isn't the way you start a querystring. A '?' is. That must have been something that a forum software update broke. It's fixed now.
