Jam Band is a special edition of "Music Maker Producer Edition" which is a DAW released by AH-Software that uses "cute girl" mascots to represent it. Jam Band is also featured on other AHS software such as "Sound Pool".
In 2010 there was an iOS app created by JetgameLab, which is named jamSlidePuzzle. The game is a sliding puzzle game that you can play while listening to background music and character voices. The game was later updated in 2011 with the addition of a new stage and a sound test mode. It's requires iOS 4.2 to run. It is compatible with Iphone, Ipad, and Ipod Touch. 
It also has a sequel called "jamSlidePuzzle2", released on Febuary 4th, 2013. It features new stages, and music. It's optimized for Iphone 5 but is compatible with Iphone, Ipad, and Ipod Touch, as long as the device has iOS 6.0 or later. Both of these apps cost ¥100 (roughly; $0.99 USD) each. 
First created on January 17, 2012, Jetman Inc. has created different theme packs for the Jam Band characters. Jetman Inc. first created the theme pack only featuring Tsurumaki Maki, but over time, Jetman Inc. has developed different theme packs featuring other Jam Band members such as, Amane Kana, Tsutsumi Rythm, and Tsutsumi Kanon, respectively. In addition to these new theme packs, Jetman Inc. has also developed a new version of the Tsurumaki Maki theme labled "Jam Band: Tsurumaki Maki ver. 2.0" (jamバンド・弦巻マキ ver.2.0). Jetman Inc. has also developed a theme pack that features all of the Jam Band members, excluding Mitarashi Mary, in their "RPG Versions". All of them cost about ¥540 (roughly; $5 USD) except the first Maki version, which costs ¥324 (roughly; $3 USD).
Pre-orders for Mitarashi Mary voice recordings known as pitagoe (ぴた声) recorded by voice actress Ito Yuina (伊藤ゆいな) began on August 26, 2021.
