Roland MKS-50 Editor and Librarian

Patch Base has the best Roland MKS-50 editor and librarian available for Mac and iPad. Edit any parameter, organize patches, create random patches, and more.

Tone Editor

Visualize the whole patch on your MKS-50, and easily edit any parameter without any menu diving. You can quickly explore all of the sonic space that the synth offers.

Patch Editor

The MKS-50 uses Patches for performance-related settings with your sounds. Select the sound you want to use, adjust detuning and portamento settings, and turn on/off external MIDI controls.

You can play the MKS-50 in Chord mode for single-key playing of chords. Patch Base gives you an editor to define the different chord structures stored on your MKS-50.
