[QUOTE="John Broadhead, post: 132116, member: 8336"] Re: Roland O.R.C.H.A Console (M-5000) discussion The M-5000 has a powerful FPGA and multiple DSPs so to fully explain what is used and why would take a bit of time - (and lots of whiteboard space). That being said, when it comes to mixing large numbers of I/O, it can yield a very broad dynamic range so to achieve a result with no loss in information required 72-bit linear summing bus circuitry. That's for the mixing engine. For other processing like effects, we get much better results (i.e., sophisticated algorithms) by using floating point processing. That plays into other decisions that contribute to aspects like a smooth EQ, for example - instead of using algorithms widely used in many digital consoles, we employed a “state variable filter” algorithm which is more typical in higher-end outboard gear.
