We spoke to Henrik from Sound Service at Superbooth 2023 about the new Kurzweil SP7 Grand, the latest stage piano in the SP range. The SP7 Grand has a touch screen to change sounds and also has two audio inputs with phantom power that can handle mic or guitar signals.
The SP7 has an SD card slot for future Sound Banks and a built-in harmonizer which can add layers to your voice.
It is available now and retails for around 2,050 Euros
