Pl4 I use these for 2 years and never failed me ...
Use mobile disco, orchestra, stage lighting, theater ... This is the solution to all situations.
I also changed Color4 musicforce from home and it is combined well.
The pl4 is a must for me in this field despite its continued high prices in nine (€ 1,000) and time (500 €).
It is a purchase you will not regret for sure. In addition to small console is very simple and allows the maximum opportunity possible in combos and color change. (I have the pedals)
Only problem, the incompatibility and dmx is frankly bad.
