Spectrasonics Stylus RMX Xpanded

A groove and loop engine built on the S.A.G.E. system with Time Designer, a capable pro-tier tool for real-time beat manipulation. It's aimed at producers who build tracks from sliced loop libraries and want hands-on rhythmic control. If you need a multisampled melodic instrument, this isn't it — it's a dedicated groove tool.
