How to fit a 3-minute song into 62 notes

A pop song runs three or four minutes. Bluejay gives you 62 notes per motor. At a comfortable two notes per second that's about half a minute of melody. So no, the whole song doesn't fit. The trick is picking the 30 seconds that people will actually recognise.

Here's a workflow that's worked for us over and over.

1. Find the hook

What's the part of the song that makes you go "oh, that one"? Usually one of:

• The opening. Star Wars, James Bond, Game of Thrones — the first four bars are the whole song's identity.
• The chorus. Most pop songs. Skip the verses, go straight to it.
• A signature riff. Mission: Impossible, Pirates of the Caribbean — sometimes only four bars long.

Just listen. The recognisable bit is obvious once you stop looking for it.

2. Crop the time window

In the converter's Start / End fields, set the range to your hook. Everything outside disappears. Try a few crop choices and use the preview — your ears will tell you fast whether the crop is right.

Common mistakes:

• Cropping mid-phrase. Land on a downbeat. Stopping a hook half-way through a held note sounds abrupt.
• Leaving in the count-in. A two-second silent intro burns four notes of nothing. Trim it.
• Picking too much. When in doubt, crop tighter. A ten-second hook that's complete beats a thirty-second medley that's missing pieces.

3. Shed voices

Most MIDIs have more tracks than your quad has motors. Open the Tracks checklist and uncheck what you don't need. Keep:

• The melody. Always.
• The bass line. Almost always — gives the song weight.
• A countermelody or harmony, if there's room.

Drop pads, doubled voices, percussion. They eat motor lanes without adding much that's recognisable.

4. Pin smartly

If the converter routes your melody to motor 4 and your bass to motor 1, the geometry of your quad will mirror the music wrongly. You want melody up front (motors 1 and 2) and bass at the back (3 and 4). Or whichever orientation makes sense for your specific frame.

Select notes in the editor and pin them. The newer pin wins displacement, so once you pin a few melody notes to motor 1, the rest will follow naturally with track affinity on.

5. Prune dropped notes manually

The converter shows which notes got dropped — they're faded in the editor. Decide for each:

• Drop for good if it's a repeated note in a chord no one will miss.
• Swap with a dropped note by deactivating an inner voice so the melody note can fit instead. The editor's capacity check makes this safe.

6. Octave shift if it sounds weak

If your MIDI was written for piano or orchestra, it might sit too low to play cleanly. Nudge the Octave shift up by 1 or 2. Bluejay tops out around C7. Aim to keep most notes in octaves 5 and 6 — that's the projection sweet spot.

7. Preview, iterate

Hit Preview together. Listen on speakers. If something sounds wrong, find it in the editor and tweak. Repeat until you can't hear anything jarring.

That's it. Most songs take 10–20 minutes from raw MIDI to "ready to flash" once you've done it a few times.

Pitfalls to avoid

• Songs in 6/8 or odd time signatures quantise poorly to RTTTL's strict grid. Pick 4/4 or 3/4.
• Songs with triplets lose subtlety. Round to swung eighths or accept the loss.
• Songs with key changes inside the hook look weird in the editor (notes suddenly out of range). Crop before the modulation.

Worked example

Bohemian Rhapsody, fitting the "I see a little silhouetto of a man" section into a four-motor quad: cropped to 12 seconds of source, kept lead + bass + harmony, pinned lead to motors 1 and 2 and the call-and-response harmony to motors 3 and 4. Final: 58 notes on motor 1, 41 on motor 2, 37 on motor 3, 39 on motor 4. Fits with room. Sounds unmistakable.

The converter never replaces taste. But for the mechanical part of compressing a long song into a byte-budget loop, these seven steps will get you 80% of the way every time.
