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 you have a Logitech webcam and can't get your keyboard/adapter to work, see this post.
Hi I'm Sakuya from Japan.
My keyboard seems to receive one channel only and is not able to play left hand notes.
Is there any way to assign left hand and right hand to the same MIDI channel?
Yes, but you need another program for it. I think Anvil Studio lets you assign tracks to MIDI channels, not sure since I don't have it set up on my laptop anymore.
