Cronet, I think the 5050 is the same as the Roland Fantom in the effects section, and if so, the following screen shot of the effect, and TEXT taken from Rolands Fantonm spec, will apply to the 5050 too
Quote from Roland on the Fantom EFX:
Powerful Effects Processing Effects processing is a powerful part of today's sound, and the Fantom includes the history of Roland and BOSS effects. From crystal clear 24-bit reverbs, rhythmic slicer and tempo-based delays, grunge inducing LoFi and Noise processors, to authentic COSM guitar amp and cabinet models, there are 90 MFX algorithms to shape your sounds.
The Fantom features five effect processors - reverb, chorus and 3 MFX processors - plus a 2-band EQ per output. You can choose from any of 50 MFX which can be used three at a time - flanger, overdrive, and slicer; rotary, distortion>delay, and enhancer; etc. The largest algorithms allow one MFX algorithm at a time, but many of those algorithms include multiple effects within an algorithm. For example, Guitar Multi A includes Compressor, Overdrive/Distortion, Amp Simulator, Delay, and Chorus/Flange - five effects on the one processor!
The Fantom also includes new MFX Templates - 96 pre-programmed effects patches to get you dialed in even faster.
