| The MIDI Synthesizer gives the possibility to connect your Paper Bits to any Midi Keyboard, such as the [[sound_boards:midi_keyboard|MIDI Keyboard]]. It is polyphonic up to six notes and has four different waveforms: square, triangle, saw tooth and sine.\\ | The MIDI Synthesizer gives the possibility to connect your Paper Bits to any Midi Keyboard, such as the [[sound_boards:midi_keyboard|MIDI Keyboard]].

| Unfortunately the latest version of Arduino is responsible for a timing glitch in the Mozzi library. Arduino changed the compiler from O2 to Os. Now the uploaded code is smaller but a timing problem appears, too. Here is an description about the problem here: | Unfortunately the latest version of Arduino is responsible for a timing glitch in the Mozzi library. Arduino changed the compiler from O2 to Os.
