I stopped making this custom because I put “Text events” instead of Lyrics in the Vocal Track, so I got bored.

Run it through MIDI Cleaner, that should fix it

Here’s a triage pass based on 15 minutes or less of analysis. This gives potential sponsors an idea of how much work might be required, and gives the original author some basic feedback.

This song needs too much work to be a Show Floor candidate.

Readiness: 2/10

Source: you supplied a 128k ogg. If you use that to render the WAV file Magma uses, the final audio quality won’t be good enough in-game.

Tempo map – there are huge jumps in tempo from one measure to the next (e.g., M9.1 95 bpm, M9.2 98 bpm). This over-under means it’ll be very difficult for the player to maintain a streak. Ideally you should be dropping one tempo change at the start of each measure.

Missing animations.

Drums: Your strongest suit.

Bass:

M8.1 – this isn’t how RB3 slides are charted – only the last note of the slide should be charted, and as a hopo. Also applies to guitar.

M11.2 These three ascending notes are all red gems. The orange at 11.4 is the same pitch as the previous red. Many of those sorts of issues throughout.

Vocals:

Part vocals looks like it was slid 10/64 right of the proper timing – it should be the same as HARM1.

These aren’t the right pitches.

Syllable timing is way off. Scrub mode is the best way to get accurate syllable timing.

There should be at least a 2/64 gap in between syllables.

Pro keys:

These aren’t the right notes. Almost all chords should be 3 notes. Watch it slow:

M3.1 through M3.2.66 should be the same chord – he’s just changing which note is accented.

A MIDI of this song’s keys should be very, very easy to find.
