Choosing a sound module for keyboards pianos comes down to the sounds you want your MIDI keyboard to access. Three V3 Sound Grand Piano Pro entries share the same piano-focused title, while condition and listed price separate them. The V3 Sound Sonority Pro Sound Module changes the question by moving from 56 onboard sounds to a 1,000-sound collection with 256-voice polyphony.
Quick take
Start with the lower-priced refurbished Grand Piano Pro if a piano-oriented module is the priority. Select the New Grand Piano Pro when that condition is central to the decision. The Sonority Pro is the clearer fit for players who want instruments, percussion, and a substantially wider sound selection from one module. Across all four choices, the listed-price spread is $90.

Product notes
V3 Sound Grand Piano Pro Sound Module - Very Good - Refurbished, USD 539.99
This refurbished version is aimed at a MIDI-keyboard player who wants the Grand Piano Pro's stated 56 onboard sounds, USB MIDI compatibility, an onboard MIDI input, and sustain-pedal control. Master volume and reverb controls add direct control over the module's output. Its concrete limitation is its position between the two other Grand Piano Pro offers: it shares model 99502US and Very Good - Refurbished condition with a lower-priced counterpart. Choose it for the listed Grand Piano Pro feature set rather than for a distinct model or condition advantage over the other refurbished version.
V3 Sound Grand Piano Pro Sound Module - Very Good - Refurbished, USD 509.99
At USD 509.99, this is the lowest-priced listed route to the V3 Sound Grand Piano Pro Sound Module. It is marked Very Good - Refurbished and is one of two such Grand Piano Pro entries in the comparison. Choose it when the lower listed price is the deciding point between the otherwise identically titled refurbished Grand Piano Pro modules. The limitation is the condition distinction: this is not the New Grand Piano Pro entry. It is therefore a direct price-and-condition choice, rather than a different Grand Piano Pro model or a change to the named sound-module format.
V3 Sound Grand Piano Pro Sound Module - New, USD 599.99
This Grand Piano Pro version is the right fit when a New unit is the deciding requirement. Its described setup includes 56 onboard sounds, a sustain-pedal input, plus master volume and reverb controls, keeping its focus on immediate piano tones for a MIDI keyboard. The limitation is price positioning: USD 599.99 places it at the high end of the comparison, while the same Grand Piano Pro title is also available in Very Good - Refurbished condition at lower listed prices. Select this version when the New condition outweighs that listed-price difference.
V3 Sound Sonority Pro Sound Module
For a MIDI setup that needs a broad instrument palette rather than a Grand Piano Pro focus, the V3 Sound Sonority Pro Sound Module is the more expansive choice. It is described with 1,000 onboard sounds, 256-voice polyphony, USB MIDI compatibility, MIDI input, and sustain-pedal input. Round-robin sample technology and Low Distortion Differential output are also part of its stated feature set. Its limitation is price positioning: it shares the highest listed price in the comparison. Pick it when the 1,000-sound, 256-voice specification is more relevant to your keyboard setup than the Grand Piano Pro's piano-oriented sound collection.
Final recommendation by use case
For a piano-centered MIDI setup with the lowest listed price, choose the USD 509.99 V3 Sound Grand Piano Pro Sound Module. Choose the New Grand Piano Pro if condition is the first priority. The Sonority Pro is the stronger match for players building a wider multi-instrument sound palette around one MIDI keyboard. The USD 539.99 refurbished Grand Piano Pro remains a middle-priced alternative, but it does not introduce a separate model or condition distinction over the lower-priced refurbished Grand Piano Pro.
