KEYS & PRO KEYS
WORK IN PROGRESS!
This page details how to author the Keyboard, both the 5-lane simplified version and the full Pro Keys experience played on a MIDI keyboard.
The 5-lane part is authored on the “PART KEYS” track.
Pro Keys is authored across multiple tracks:
- PART REAL_KEYS_X - The Expert Pro Keys chart
- PART REAL_KEYS_H - The Hard Pro Keys chart
- PART REAL_KEYS_M - The Medium Pro Keys chart
- PART REAL_KEYS_E - The Easy Pro Keys chart
It also has two separate animation-specific tracks:
- PART KEYS_ANIM_RH - Right hand animations
- PART KEYS_ANIM_LH - Left hand animations
5-LANE KEYS
5-Lane is a version of the Keys compressed down to 5-button gameplay, playable on both a plastic guitar and a MIDI keyboard. This aims to be a very similar gameplay experience to that of the 5-lane Guitar and Bass charts, and in general follow most of the same rules. You'll usually want to chart Pro Keys first, then do 5-lane using the Pro chart as a reference.
Here are the biggest differences between 5-Lane Keys and 5-Lane Guitar & Bass rules:
Chords
Keys allows for 3-note chord shapes that are not permitted on Guitar or Bass:
- Green / Red / Orange
- Green / Yellow / Orange
- Green / Blue / Orange
This is because playing Keys uses different hand movements than playing Guitar/Bass, for example allowing you to easily use your thumb or a second hand while playing.
Broken Chord Sustains
On Keys you can have sustains that overlap with other notes, without needing to begin or end at the exact same time as them.
For example, you can have a Green sustain, and while holding it you're playing a Red note during it.
Reduction Wrapping
Medium and Easy difficulty on Keys can still use all 5 note colors. This in general makes Keys reductions faster to do, as you don't have to wrap stuff as often.
