Yamaha Synths Official Unveils CP73 OS v2.0: A Stage Piano Update with Depth and Finesse

The heart of the OS v2.0 update lies in the introduction of two new grand piano voices: CFX2 and Imperial+. These are not just incremental patches but represent freshly sampled and re-voiced instruments, each with a distinct character. The demo compares the original CFX and Imperial voices with their new counterparts, allowing listeners to hear subtle but important differences in tonal bloom, low-end depth, and note clarity.

The CFX2 is described as having a thicker, rounder sound with more note bloom and a beefier low end, while still retaining the strong fundamental that makes it cut through a mix. The Imperial+ receives similar treatment, with the re-voiced version offering enhanced clarity and a more pronounced low end. Both new voices are presented as alternatives rather than replacements, giving players more options to match their personal taste or the demands of a particular performance.

OS v2.0 brings a suite of workflow-focused features that address common stage and studio needs. The addition of Tempo Delay with tap tempo is a direct response to user requests, allowing performers to sync delay effects to the band or drummer in real time. The implementation is straightforward: select the delay type, activate tempo mode, and tap in the desired tempo—no menu diving required. This is a clear nod to Yamaha’s commitment to live usability.

Another major enhancement is the adjustable output gain control. Instead of relying solely on external mixers or negotiating with sound engineers, players can now fine-tune the CP73’s output level in 3dB increments, up to ±24dB. This feature is particularly useful for adapting to unpredictable live environments, giving musicians more autonomy over their stage sound without awkward conversations at the board.

The adjustable damper resonance moves beyond the traditional on/off switch, allowing for subtle or dramatic changes to the piano’s sustain character. The demo shows how this can be used not just for realism but as a creative effect, transforming the piano into a pad-like texture or dialing it back for a drier, more percussive sound. These updates collectively make the CP73 more adaptable and performance-friendly, especially for players who value hands-on control.

A standout feature in OS v2.0 is seamless sound switching, both between live sets and within individual sections. This means that when changing sounds mid-performance, the previous sound sustains naturally until the player releases the keys, eliminating the dreaded audio gap that can disrupt a live set. The presenters emphasize how this reduces anxiety for performers who need to transition between sounds on the fly.

This enhancement is especially relevant for genres like gospel and church music, where quick changes between lush pads and piano leads are common. By holding the previous sound until the next note is played, Yamaha ensures that the CP73 keeps up with the demands of modern, dynamic performance environments. It’s a workflow improvement that feels small on paper but makes a big difference on stage.
