The Roland SH-01A Module with K-25m Keyboard is an all-in-one bundle featuring the 2017 SH-01A module complete with the K-25m keyboard that connects directly to the module. The Roland SH-01A synth is a compact faithful reproduction of the classic SH-101 from Roland. Utilising the same oscillator filter and envelope tones from the original the SH-01A Sound Module provides vintage-style synthesis. It now includes a new polyphonic mode accompanied by unison and chord modes for expansive sound creation capabilities. The Roland K-25m Keyboard is an expansion module compatible with the Roland SH-01A which allows you to dock and connect the 25-key velocity sensitive keyboard to the module.
