On the topic of performing: is it the stage you have your sights on? In that case, set your sights on stage pianos, like the Roland RD-300NX for example. Powered by Roland's proprietary "SuperNATURAL" sound engine, it's so true-to-life that an audience just might find themselves wondering where you've hidden the baby grand. Another great suggestion is the Nord Stage 2 88-Key Stage Keyboard, which uses three sound-generating sections working together to provide outstanding versatility.
Since there are so many digital pianos worthy of your attention in this catalog, you may want to narrow down your choices using some of the search options on the sidebar. For example, if you select stage digital pianos under the category section, you'll be presented with all the digital pianos that were made for the stage. Once here you have the opportunity to drill down even further and can search by topics like number of keys, MIDI/USB Connections or by whether or not the digital piano has built-in speakers.
