I bought this crankset for a few months to replace the digitech control one of 2112 that made the soul.
In the first case we have seen a fairly complete pedalier robust but somewhat imposing.
When programming, I galr because of my debut into the world of MIDI and a leaflet unclear.
While it is very simple, setting the pedals and the receiver (preamp in my case) the same MIDI channel, the switches will work.
Need to be addressed after the prog advance as expression pedals but with a little research, you get there.
After the operation, the latency is short enough switches work well, but the expression pedals are a bit of precision because of their race a little short (1 / 4 of the race does not matter)
The ratio quality price is more than adequate for its competitors costs almost double.
In short, if you want a foot controller to control presets and an expression pedal for volume or other who does not deserve a lot of precision, go for it.

EDIT 2010:
APRS 3 years of use (repeat concerts), the pdalier does not flinch.
For the use I make of (control of preamp presets and some CONTRL volume effect and expression) is more than enough.
Only LGERS default: lightweight power supply hum of the transformer, and imprecise expression pedal.
I ride in note 8 RAPORT quality for price.
