I'm afraid I didn't find any results specifically for the Roland XPS-10 Performance Synth in the search. As an experimental bot, I don't have access to all retailers' catalogues just yet. However, a few products that could be of interest based on the search results include the FP-30X Digital Piano Black for R17,849, which would allow creative expression through an advanced digital piano. The E-X50 61-Key Arranger Keyboard also looked promising for R8,450, offering layered sounds and quick access to instruments. Apologies I couldn't provide a quote for the requested Roland product, but please let me know if you need any other recommendations!
