Shopping for keyboards pianos can mean two very different things: protecting an instrument you already own or bringing home a piano to play. The Yamaha SC-DE61 Backpack Style Soft Case and Yamaha P-145BT P-Series answer those separate needs, so the practical choice is clear once you decide whether your priority is transport or performance.
Quick verdict
Choose the Yamaha SC-DE61 Backpack Style Soft Case Pro Audio for CK61 when you already use a CK61 and want a black backpack-style case for an electronic keyboard. Choose the Yamaha Pro Audio P145BT P-Series 88-Key Digital Piano with Bluetooth when you want an instrument for learning, rehearsing, or playing at home, with weighted keys and Bluetooth audio.
These are not like-for-like keyboard purchases. The listed price spread is $209.64, reflecting the difference between a case/bag and a complete digital home piano.

Where each product wins
The SC-DE61 wins when your main need is to carry a CK61 keyboard in a purpose-named soft case. Its title identifies it as backpack style, and the black color gives it a straightforward stage-gear look. This is the relevant pick for a player who already has the instrument and is choosing an accessory rather than another keyboard.
The P-145BT wins for someone choosing an actual piano-playing setup. Its 88-key layout, touch-sensitive weighted keys, and grand-piano-focused description suit learning and practicing piano parts. Bluetooth audio also lets you stream music through the piano's speakers to play along. Its slim design is positioned for a home setting, whether you are starting out or returning to playing.
Product notes
Yamaha SC-DE61 Backpack Style Soft Case Pro Audio for CK61 New from Japan
Pick the SC-DE61 when a Yamaha CK61 is already part of your setup and you want a carrying solution identified specifically for that keyboard. The backpack-style format is the central reason to choose it, especially for moving an electronic keyboard between practice, rehearsal, and performance spaces. It is listed as a new black Yamaha case/bag, with Japan identified as the country of origin. The key limitation is equally important: this is a case rather than an instrument. It will not add keys, sounds, speakers, or a practice function to your setup. At USD 260.35, it makes sense when secure, dedicated transport is the purchase you need to make.
Yamaha Pro Audio P145BT P-Series 88-Key Digital Piano with Bluetooth
The P-145BT is the appropriate choice when you need a playable digital piano rather than an accessory. Its 88 weighted, touch-sensitive keys are positioned for an expressive acoustic-like piano experience, while the P-Series format is described for rehearsing, learning, and creating. Built-in Bluetooth audio is a useful fit for players who want to stream songs and play along through the piano speakers. The slim styling also suits a home-focused instrument setup. Its limitation in this comparison is that it does not address the SC-DE61's CK61-specific carrying purpose; it is a digital home piano, not the backpack-style case. At USD 469.99, it is the more complete choice for beginning or resuming piano playing.
Final choice by use case
- Choose the Yamaha SC-DE61 if you own a CK61 and the immediate goal is a backpack-style soft case for carrying an electronic keyboard.
- Choose the Yamaha P-145BT if you need an 88-key digital piano for practice, learning, rehearsals, and playing along with Bluetooth audio.
- Choose neither as a substitute for the other: one purchase centers on CK61 transport, while the other centers on making music at a digital piano.
