Neither the R16 or R24 have motorized faders. Per PG Music support neither BIAB or RealBand support surface control operation.

The R24 uses components and firmware one generation newer than the R16. The R16 uses the same firmware family and major sound components found in Zoom's HD-8 and HD-16. The R8 actually has more althorythm presets and more input flexability than the R24. The R8 and R24 share firmware families as well as major sound components and are likely the last desktop sized digital recorders that Zoom will make. Presently Zoom is concentrating on the handheld digital recorder market.

Whichever you choose, Zoom makes products with a high feature set to price ratio. I have an older MRS-8 unit that continues to work as well now as it did new in 2007. I've been very happy with it.
