About

Converts a midi file (.mid) into a TrombLoader chart.

Most of the instructions for how to make a chart are on the Trombone Champ modding Discord:
https://discord.gg/KVzKRsbetJ

Usage:

Upload the midi above.
Fill out the form
- All fields must be filled in, except Song Endpoint
- Use whole numbers whenever possible: Decimals are not guaranteed to work
- Hover over the names of each field to see detailed info
Click Generate Chart. The result will be downloaded as song.tmb

Notes:

Midi notes should be in the range 47 to 73 to match the game. Any notes outside this range will likely be unplayable.
Quantize your charts, the game hates unquantized notes.
Some midi editors use velocity 0 to indicate a note should turn off. This supports that. Don't otherwise set velocity to 0.
Unlike Midi2TromboneChamp, this squashes all tracks and has no slide track.

Slide modes

TCCC can interpret midi files in two ways to create slide notes. They are not interchangeable: Slides made for tccc mode will likely not convert properly in other converters.

In the below examples, blue notes are midi notes. Note that a vertical gray line in the middle of a midi note indicates that the note is released and pressed again. The green line is the Trombone Champ notes that will be generated.

midi2tc mode

This is the format used by midi2tc.exe. When two notes overlap, the slide will start at the time and pitch of the start of the first note and end at the time and pitch of the start of the second note.

Note starts with a slide:

Multiple slides:

Note ends with a slide: This is not possible in midi2tc slide mode. In midi2tc.exe 0.3.0 and earlier, it can be done by using channel 2.

tccc mode

This is TCCC's own format. When two notes overlap, the slide will start at the time and pitch of the start of the first note and end at the time and pitch of the end of the second note.

Note starts with a slide:

Multiple slides:

Note ends with a slide:

Overlapping more than two notes is undefined behavior in tccc mode. Don't do it.

Pitch Bend Events

TCCC can perform additional adjustments to the pitch of notes using MIDI Pitch Bend events, allowing you to set notes to microtonal values.

The Pitch Bend Range option controls what range (in semitones) the MIDI events are converted to.

E.g. At a Pitch Bend Range of 2, a maximum value pitch bend MIDI event will raise/lower the note pitch by 2 semitones.
Make sure this range matches the range of the DAW output device you used when making the MIDI (e.g. your synth plugin, soundfont player, etc).

Most default to +-2 semitones, but it varies across devices so it's best to check your setup.

TCCC takes the pitch bend values at the start and end of a particular note, and shifts the start/end by that amount.

Examples

Pitch bend event covers all notes, so all are shifted up by the same amount (the unadjusted note is shown faded out). Make sure your desired pitch bend finishes after the note end.

Pitch bend event covers just the start of the first note of the slide, so the start is shifted down.

You can shift the start/end of a single-note slide by placing the pitch bend around just the start/end note. In this case the end of the slide is shifted down.

When shifting a note connected to the end of a slide, make sure to shift both the end note and the slide note that connects to it.

For pitch shift gradients/curves, the pitch shift amount is taken at the start and end of each note.
