Independent shopping perspective
RK-100S 2 is a red, 37-key slim keytar/synthesizer designed to take its sound engine and physical controls onto a stage. Its wooden body carries a clear finish, so grain varies from one unit to another. Choose from 200 programs, recall preferred sounds from top-panel Favorite buttons, and use the arpeggiator plus two ribbon controllers for pitch, modulation, or filter moves. Battery operation can provide approximately eight hours with alkaline AAs; the included strap and dedicated soft case support moving it between sets.
