1 About Rosetta

Rosetta began on the Roland U-110. There, you put your own sounds in the place where the factory sounds were. Now it does the same job on the D-110. A D-10 version is on the way.

Rosetta ROMYour own sounds, inside the synth.
Rosetta OSExtra things to play with. This manual.

2 Before you start

Install noteTwo chips. The OS chip is the same since v8, so an update only swaps the control chip. v12 boots and works on a real unit.

Switch it on. First you see the Rosetta boot screen for a moment:

Then the normal D-110 screen comes up. Everything Roland made still works. Your Rosetta settings stay saved when you switch it off.

The menu is hiddenThe Rosetta menu does not show up on its own. Hold Enter, then press Edit to open it. See chapter 3.

Knobs over MIDI: CC74 cutoff, CC71 resonance, CC73 attack, CC72 release.

Cutoff and resonance only work on synth sounds. They do not work on samples (PCM).

Open the quick screen. Press Edit. One line = one feature. A > means the line has more settings inside.
