Streamline Your Performance

The S90 XS/S70 XS also lets you quickly and conveniently create your own custom Performances, with the amazingly fast and easy Performance Creator feature. It's never been easier to select a Voice, then quickly program Layers and Splits - even assigning a Drum Voice complete with arps to create your perfect Performance.
Let's say that you're playing a piano Voice and you want to layer a string sound on top of it. Simply press the [LAYER] button, then select the desired Voice category and Voice, and store your new Performance - just a few button presses and you're there!
Plus the panel controls of the S90 XS/S70 XS have been designed and positioned for optimum, intuitive operation, especially for live performance. For example, you can quickly select a Part, turn it on/off, set Arpeggio on/off, switch Arpeggio Hold - all done easily with the top panel controls - and instantly tweak important synth parameters via the Knobs and Sliders.
The perfect Performance has never been easier to create and control.

Ideal for Live Performers

If you've got a USB memory device or thumb drive, you can plug it into the S90 XS/S70 XS and record your performance as audio data. This remarkable feature lets you instantly capture what you play on the keyboard - including arpeggio playback - to your USB device.
If you've connected a microphone or guitar, you can even record your singing or playing as well. You can also record audio directly to the internal flash memory (192 MB) built into the instrument, without the need of a memory device.
And keep in mind that anything you've recorded to the memory device, even audio files created on your computer, can be played back on the S90 XS/S70 XS - which means you can create your own custom audio backing tracks and perform along with them on the S90 XS/S70 XS. For example, you can create a basic song track beforehand, then sing and solo over it during your performance. Or add guitar parts and vocal harmonies to be played back with your live performance. There's also a useful Song Chain function that lets you string together separate recordings and create a convenient backing track "set list" for your gigs.
