Edit the 4 available mod routings for deep sound modulation
Copy and paste entire Timbres, to mix and match layers between sounds or to make big, detuned patches

Add new sounds and rearrange sounds on your MS2000, directly from Patch Base. With the Bank Editor, you can easily back up all of the stored sounds on the synth, save them to a file, and load an entire new bank of 128 sounds in seconds.
