== Trivia ==
[[Image:DeltaMAX banner.png|thumb|ΔMAX's banner.]]
* ΔMAX was originally the EXTRA STAGE of ''DDR Forever'', a fan-made DanceDanceRevolution game that was run by the ''StepMania'' simulator.
** As such, ΔMAX is the first BEMANI song that was first originated on a BEMANI simulator.
* ΔMAX has a unique video, which is played full-screen and eliminates any on-screen dancers (except in [[CS DDR S+|DanceDanceRevolution S+]]), based on DanceDanceRevolution UNIVERSE3's generic videos.
** In [[CS DDR II|DanceDanceRevolution II/DanceDanceRevolution hottest party5]], ΔMAX's video is played in a tiny monitor on the opposite side of the player on Single and in the center on Double/Versus, due to Nintendo Wii memory limitations.
* ΔMAX's BPM starts at 100 and gradually builds up by 1 BPM per quarter beat until it hits 573 BPM. This is shown by its unique video.
** The same sound effect is played every time the BPM hits a multiple of 100; this is accompanied in ΔMAX's video with a cut-in announcing a new "section".
** A post by DM Ashura on [https://www.reddit.com/r/learnmath/comments/5d7kz2/calculus_a_speedincreasing_song/da530gf/ reddit] details ΔMAX's BPM changes.
** With 473 BPM changes, ΔMAX holds the record of having highest number of BPM changes of ''any'' BEMANI song.
** ΔMAX's final BPM, 573, is a reference to the KONAMI number.
*** Also, ΔMAX's EXPERT charts have 573 notes.
* Δ is the uppercase Greek letter "Delta", the fourth letter in the Greek alphabet. In mathematics and science, an uppercase Δ is a common abbreviation for "change" (e.g. Δ''x'' is shorthand for "change in ''x''").
** This might be a reference to ΔMAX's constant gradual BPM changes.
* In DanceDanceRevolution UNIVERSE3, ΔMAX can be unlocked in QUEST MODE by beating Simba on the final floor of the Universe Tower.
* As of December 24th, 2010, ΔMAX's CHALLENGE charts have been made available for play in DanceDanceRevolution X2. These charts were written by DM Ashura himself as the original EXPERT charts planned for ΔMAX.
** ΔMAX's CHALLENGE charts were not playable in the North American/European arcade release of DanceDanceRevolution X2 due to the lack of [[E-AMUSEMENT|e-AMUSEMENT]] in those regions.
** They were finally made playable on DanceDanceRevolution II/DanceDanceRevolution hottest party5 as well as the North American/European arcade release of [[AC DDR A|DanceDanceRevolution A]].
* ΔMAX appears as downloadable content for DanceDanceRevolution S+, in the '''Mega Mix 6''' pack.
* ΔMAX is used as background music in a mission on the KONAMI arcade game ''ROAD FIGHTERS'' (ロードファイターズ).
* In DanceDanceRevolution II, ΔMAX is one of the ''Replicant D-action'' hidden songs.
* ΔMAX can be unlocked in REFLEC BEAT groovin'!! Upper from July 26th, 2015 as part of the [[BEMANI SUMMER DIARY 2015]] event.
** In [[AC RB VOLZZA|REFLEC BEAT VOLZZA]], it could be purchased in the Garage from November 16th, 2015 after obtaining 20 VOLZZA KEYs.
*** In [[AC RB VOLZZA 2|REFLEC BEAT VOLZZA 2]], it was playable by default.
** ΔMAX being crossed over marks DM Ashura's only appearance in the REFLEC BEAT series.
** Also ΔMAX, reaching up to 573 BPM, currently holds the record for the song with the highest BPM at any point in the REFLEC BEAT series, topping [[Ongaku|音楽]]'s 520.
* ΔMAX is the first DanceDanceRevolution crossover song in REFLEC BEAT with a HARD chart rated Level 10+ (11 in REFLEC BEAT VOLZZA/VOLZZA 2).
* When sorted alphabetically, ΔMAX was sorted under the "number & symbol" (数字 記号) folder in [[AC DDR 2013|DanceDanceRevolution (2013)]] and [[AC DDR 2014|DanceDanceRevolution (2014)]]. The name of this folder changed to "NUMBER" in DanceDanceRevolution A, which resulted in ΔMAX being erroneously sorted under it. This was fixed on June 9th, 2016 by moving ΔMAX to the "D" folder.
* ΔMAX was one of the qualifying round songs in the [[KONAMI Arcade Championship|The 6th KONAMI Arcade Championship]] for DanceDanceRevolution A.
* ΔMAX's difficulty changes from [[AC DDR A20|DanceDanceRevolution A20]] were applied to DanceDanceRevolution A in March 27th, 2019.
