Wanderer's Minuet Clarification

The reposted/re-edited Live Letter Digest reads as follows:

"The largest aspect for bard is the new song, The Wanderer’s Minuet. This song allows you to switch into a stance that charges up your bow. While under the effect of this song, your DPS will be boosted, but you will no longer be able to perform auto-attacks or attack while moving. MP will not be consumed when using this song and you can also have other song effects active while using it. When you want to avoid enemy attacks, even if you’re using The Wanderer’s Minuet your DPS will be reduced, so you can remove the effect, fight while you evade, and then resume the effect for more firepower if you'd like.

Additionally, a new action called “Sidewinder” will also be added, and the damage it inflicts will be boosted based on the number of DoTs you've already placed on your target. The new concept of bard is to fight while switching songs and using all of these techniques."

Am I understanding it correctly to think that even with Wanderer's Minuet active, should you move, you can still DPS (as you would normally) but without the effects of Minuet? Basically an "On while stationary/Off in motion" state? I've been wondering about this since it was announced. Also, can the same be said for the Machinist's Gauss Barrel?

While it's active, it turns you into a black mage. If you move, it interrupts the skill.
