Video Output
Plug the HDMI cable out of the DVI video output on the Metro RP2350 and into your HDMI monitor.
Note: some monitors aren't capable of displaying 640x480, in which case you'll see a blank screen.
The monitor linked in the Parts section of this guide is a good bet if you need a small 640x480 4:3 ratio display. You'll also often find that older LCD televisions are 640x480 capable.
Audio Output
Plug a 3.5mm TRS audio cable into the DAC output and either your TV's audio input if available or a set of powered speakers or headphones.
Mouse Input
Just like with Mario Paint, the only input device you'll need for Larsio Paint Music is a mouse. Plug a USB mouse into the USB A connector.
Usage
Making music with Larsio Paint Music is fun and simple -- just add notes where you like and hit play! You can add notes while it's playing for fast composition.
Voice Select
There are six types of sounds (called "voices") you can play with. Click the icons in the upper left corner to choose among them. The first three are wav samples, the other three are synthio synthesizer voices.
- Lars - pitched sample of eveyone's favorite creepy sloth, Lars
- Heart - bass multi-sample
- Drums - multiple drum samples: kick, snare, closed hihat, open hihat, crash cymbal
- Meatball - synthesizer sine wave notes
- Star - synthesizer triangle wave notes
- Robot - synthesizer sawtooth wave notes
Add Notes
Hover the cursor over the music staff -- you'll see that you're dragging a Lars note around. Click anywhere on the staff with the left mouse button (LMB) to place a note and hear a preview.
Delete Notes
If you don't like where you placed the note, delete it by hovering over it and right mouse button (RMB) clicking it.
There is no strict limit to polyphony, so you can stack up chords, beats, and melodies, but it is likely that you'll run into timing issues at hire tempo rates with lots and lots of notes.
Play
Hover over the transport control section on the bottom and click the triangle Play button to play the four bars.
Stop
Click the square Stop button to stop playback. The playhead will return to the beginning of the first bar.
Loop
Click the Loop button and the song will play over and over and over again until you press stop or the power goes out!
Clear
If you want to clear all the notes at once, click the bomb-shaped Clear button.
