New features and enhancements include in Moog Music's own words...
This exciting new feature is used to set up multiple Moog synths as a polyphonic synth stack. One synth per voice... up to 16 voices! MIDI control numbers are consistent between the Voyager and Little Phatty, so any parameter changes such as pitch bend and mod wheel, filter cutoff and so on, affect all voices simultaneously.
Poly Mode works with the Little Phatty, the Minimoog Voyager and Voyager Rack Mount Edition. You can use either the Little Phatty or the Voyager as the master keyboard.
The preset save routine has been improved. As always, to save a preset you press the ENTER/STORE button while in Panel Mode. You will see two lines on the Little Phatty display. The top line shows the location where the preset will be saved, and the name of the preset which is currently saved in that location. No more overwriting your favorite presets by mistake.
The Modulation Wheel and Filter Cutoff parameters now send and receive high-resolution 14-bit Midi CC messages. This allows for finer control and more smooth-sounding changes, whether you are using the LP as a MIDI controller or controlling the LP via MIDI from your sequencer.
Has a new KEYB PRIORITY setting - default is GLOB (global), which inherits the Global Keyboard Priority set on the KEYBD PRIORITY menu. You can now choose to set a different keyboard priority which is saved per patch.
MIDI functions have been consolidated to one menu, and some tasty new features have been added.
MIDI SETUP contains the following items: ALL NOTES OFF, LOCAL CONTROL, MIDI MERGE, POLY.
The new features are Midi Merge and Poly. If Midi Merge is ON, the LP will echo all MIDI received at its MIDI IN port to the MIDI OUT port, merged with any Midi data which is generated by the LP. This allows you to pass Midi data THRU the LP, which was not formerly possible.
