Choosing Keyboard and Piano Add-Ons: Sustain Pedals, a CK61 Case, and a Sound Module

Shopping for keyboards pianos can mean very different things depending on what is missing from your setup. One shopper may need a piano-style sustain pedal, another may need a carry case for a CK61 keyboard, and another may want a separate sound module for MIDI keyboard use. The key is to avoid comparing these as if they all do the same job: they sit in the same broad shopping area, but they solve different problems.

Quick take

• Choose the MGEAR M-Audio SP-2 Professional UNIVERSAL Piano Style Sustain Pedal[-KEYBOARD if you want the lowest-cost SP-2 option here and are comfortable with a used condition item.
• Choose the M-Audio SP-2 Professional Piano Style Sustain Pedal. J6 if you want the same SP-2 model family in open box condition rather than used.
• Choose the Yamaha SC-DE61 Backpack Style Soft Case Pro Audio for CK61 Keyboard New if your main need is a Yamaha CK61 soft case with backpack-style carrying and accessory pockets.
• Choose the V3 Sound Grand Piano Pro Sound Module if you are shopping for a compact sound expander module rather than a pedal or case.

Listed price comparison

The listed prices range from USD 10.00 to USD 539.99, with the lowest listed price 98% below the highest. That wide spread makes sense because the group includes small pedal accessories, a keyboard case, and a sound module.

Decision matrix

If you need sustain control for piano-style playing: Start with one of the two M-Audio SP-2 listings. Both are identified as SP-2 sustain/damper pedals for piano use, so the main difference is condition and the exact listing presentation.

If you need a carrying solution: The Yamaha SC-DE61 is the only case or bag in this group. Its title names CK61 keyboard use, while the description calls out a backpack type and pockets for pedals and accessories.

If you need additional sounds from a module: The V3 Sound Grand Piano Pro is the only sound module here. Its description centers on MIDI keyboard use, 56 onboard sounds, USB MIDI compatibility, output options, a sustain pedal input, and volume and reverb controls.

If condition matters most: The Yamaha case is marked new, the M-Audio SP-2 J6 is open box, the MGEAR M-Audio SP-2 is used, and the V3 Sound module is very good refurbished. Those condition labels may be as important as the product type when narrowing your choice.

Concise product notes

MGEAR M-Audio SP-2 Professional UNIVERSAL Piano Style Sustain Pedal[-KEYBOARD

This is the most direct pick for someone who simply needs an M-Audio SP-2 sustain/damper pedal for piano use and wants the lowest listed cost among the four items. The title calls it a universal piano-style sustain pedal for keyboard use, while the attributes identify the model as SP-2 and the color as black. Its biggest limitation is the used condition, which separates it from the open box SP-2 alternative. It is also a pedal only, so it does not address carrying a keyboard or adding sounds the way the Yamaha case or V3 Sound module would.

M-Audio SP-2 Professional Piano Style Sustain Pedal. J6

The SP-2 J6 listing is another M-Audio sustain/damper pedal aimed at piano use, and the open box condition is the main reason to pick it over the used SP-2 listing. The description presents it as a piano-style sustain pedal for pianos and keyboards, which makes it a focused accessory for expressive sustain control rather than a broader keyboard upgrade. The tradeoff is that it costs more than the used SP-2 in this comparison while remaining the same general type of item. It also lacks the carrying features of the Yamaha case and the sound-generation role of the V3 Sound module.

Yamaha SC-DE61 Backpack Style Soft Case Pro Audio for CK61 Keyboard New

The Yamaha SC-DE61 is the practical choice when the problem is transporting or organizing a CK61 keyboard rather than changing how it sounds or plays. The title identifies it as a backpack-style soft case for the CK61, and the description adds pockets for pedals and accessories. It is marked new, black, and compatible with Yamaha, with the instrument type listed as electronic keyboard. The limitation is narrow use: it is a case/bag, not a sustain pedal, sound source, or keyboard. It also sits well above the two SP-2 pedal listings in listed price.

V3 Sound Grand Piano Pro Sound Module

The V3 Sound Grand Piano Pro is the only option here that expands a MIDI keyboard setup with a separate sound module. Its description highlights 56 onboard sounds, USB MIDI compatibility, MIDI input, output options, sustain pedal input, and master volume and reverb controls. That makes it the most feature-oriented choice in this group for sound generation. The limitation is equally clear: it is not a keyboard, not a case, and not a simple pedal accessory. It is also marked very good refurbished, and its listed price is the highest in this comparison by a large margin.

Final recommendation

For most shoppers, the right choice depends first on the missing piece in the setup. If you need a sustain pedal and want to spend as little as possible, the MGEAR M-Audio SP-2 Professional UNIVERSAL Piano Style Sustain Pedal[-KEYBOARD at USD 10.00 is the lowest listed price and is identified as an SP-2 sustain/damper pedal for piano use. If you prefer the open box condition label within the same SP-2 model family, the M-Audio SP-2 Professional Piano Style Sustain Pedal. J6 at USD 29.99 is the cleaner comparison point.

If your CK61 needs a dedicated carry solution, the Yamaha SC-DE61 Backpack Style Soft Case Pro Audio for CK61 Keyboard New is the only case here, with backpack-style wording and accessory-pocket language. If the goal is adding a dedicated sound source to a MIDI keyboard setup, the V3 Sound Grand Piano Pro Sound Module is the only product here built around a sound module role, with 56 onboard sounds and volume and reverb controls.
