Sometimes, when you’re just messing about on a keyboard, something unexpected happens. That’s exactly how I stumbled upon AKG – Piano Therapy—a custom piano voice I built entirely by accident on a Yamaha PSR-SX920. I was noodling away, meant to be working on something completely different, when I started tweaking a few settings and suddenly—boom—there it was. A richer, more expressive piano sound that just felt right. If you’re the kind of player who likes to lose yourself in the music, you’ll want to hear this.
Watch the video below to hear it in action:
The default CFX Concert Grand voice on the Yamaha PSR-SX series is fantastic—no doubt about it. Yamaha’s sound designers know what they’re doing, and they’ve tuned it to be bright, clear, and precise, so it cuts through the mix in a band or ensemble setting. But when I play solo, I sometimes want something a little different—something with a bit more atmosphere, something that lingers a little longer.
I wanted to take the pristine, almost clinical clarity of the default CFX sound and give it a more dreamlike, immersive quality. Imagine an Impressionist painting where the colours blur into one another, rather than sharp, distinct lines. That’s the idea behind AKG – Piano Therapy—a sound that spills over, melts into itself, and creates a fuller, more emotive playing experience.
The real game-changer here was damper resonance. The moment I adjusted it, I could feel something happening to the sound—it wasn’t just sustaining longer, but the notes were interacting with each other in a much more natural way. It became warmer, richer, and just felt more expressive to play.
A few other things I tweaked:
The result? A piano sound that feels like it’s breathing—something you don’t just hear, but feel.
I originally created this voice for solo improvisation, but honestly, I can see it working in all sorts of settings—cinematic music, orchestral arrangements, even pop ballads. The beauty of it is that it’s not a one-size-fits-all sound. Different players will use it in different ways, and I’m really excited to see how others bring it to life.
If you’ve got a Yamaha PSR-SX920 (or a similar model), you can download this voice and try it for yourself. I’m giving it away completely free because, honestly, it was one of those happy accidents that I just had to share.
Want a copy? Just email sales@epianos.co.uk, and I’ll send it straight to you.
This whole process has reminded me just how much customisation you can do on these keyboards. There’s way more to tweak than I originally thought, and after seeing how many people have already requested this sound, I’m definitely going to create more. If you’ve got ideas for a piano sound you’d love to hear, let me know—I’m happy to experiment and see what’s possible.
