ScottYee,
Yes, I transport the mic boom and the music rack both detached from the Monolith stand. The knobs are included with these options and they're extremely easy to attach to the stand once you remove the plastic plug from the Monolith arms, the first time - just like the Pro describes.
Two things must be said:
1) You might find the music rack a little too big/heavy/cumbersome and the transport not very practical. But it's very solid.
2) The mic boom can ONLY be attached to the left arm (as in The Pro's picture) and the music rack only to the right arm. You'll understand why; tomorrow I'll post a picture with details.
NO, the music rack can not tilted inwards, it's a rigid piece in which the section that inserts the Monolith arm has a rectangular shape. More details in some pics tomorrow.
Scott Langholff,
QLX series are the Quiklok model to go if you want a double X tier with optional mic boom and music rack. They are OK, but I prefer the Monolith for an edge in stability (and for other reasons I explained above). If your keyboard is heavy it can make a difference.
