- Name: Youhei Shimizu (清水洋平)
Youhei has worked with the BEMANI franchise since nearly the very beginning, starting off as the sound tool programmer on the first pop'n music. Unlike most staff members at the company, Youhei seldom stuck to one BEMANI series as a staff member: he was a sound programmer for beatmania 3rdMIX and beatmania completeMIX, then he worked on beatmania IIDX, substream, and pop'n music 4 in the same position, before becoming co-sound director of beatmania III and finally the sound director of ParaParaParadise.
- Youhei composed Reseed and Reseed (Another Edit) for CAPCOM's CROSS×BEATS and crossbeats REV..
- The alias used for Reseed and Reseed (Another Edit), quick master, references his BEMANI song of the same name.
