i want to be able to control my atari 2600 and synthcart with my keyboard, would the MIDI2600 let me do this?
and will it play a note for each key pressed, as usually synthcart only lets you play 12 notes with a joystick controller.
The MIDI2600 does not add any extra notes or other functionality to Synthcart. It simply allows you to "press the keypad buttons" with MIDI notes, rather than your fingers. (And the select/reset buttons, also.) Does that make sense?
The MIDI2600 MIDI implementation page may clarify things a little bit. It shows which keys on your MIDI keyboard will control which Atari 2600 Keypad button, joystick button, or select/reset button:
Hope this helps--please let me know if I can provide more information.
