CARD SYNTH
A pocket synthesizer: piano and pads, drums, a 16-step sequencer. Play it with your keyboard, and jam with others in the same room.
THE DEVICE
The whole Cardputer ADV: its launcher, Arcade, Synth, Calc and Recorder, with its own keyboard on screen.
WITH FRIENDS
Games with a ONLINE tag play two people across the internet: both open the game and press N. Everyone here and every Cardputer on Wi-Fi meet in the same room.
