Quoting cliff from a few pages back
"
The choice of effects was so that you couldn't overload the processor. Running a Reverb and a Plex plus the Amp block would exceed the processor's bandwidth.
Engineering is all about tradeoffs. It's a constant juggle between price, size, features, power consumption and performance. As such, no product will be perfect for everybody. In an ideal world DSPs would use no power and have infinite clock speeds. Until then products will have to make compromises.
At some point we can revisit the effects inventory."
