This Skill

Unless I'm mistaken, it also gives 15 music buff effect like Playing Instrument, just want to be sure before asking. Also, I have two questions. Do the 15 music buff effect from playing stack with singing? Does singing have a better effect on crops than playing? Do the time reductions of playing and singing stack?

It's the same from what I've been seeing...

Rank 1 singing has the 15 music buff effect.

He said it when starting up the topic. He's asking if Playing and Singing effects stack.

I"m pretty sure it's one or the other.

Yes but does the mbe or the crop time stack between the two skills? And on another note, starting r6 you can sing without a mic. Does the 15 music buff effect from singing apply when not using a mic?

Question: Does the Buff Effect from Music Talent affect Singing?

Yes it does. It's just playing instrument's 15 does not stack with singing's 15.

I wonder if equipping an instrument with +buff effect would affect singing without affecting the instrument's durability.

You still use the instrument if you have the buff with r5+ singing, but the +15 music buff from singing stacks with the +15 from playing instrument, so without anything else but those two at r1, you get 30 music buff enhancement, which is nifty.

You have to have Song at Rank 5 and an Instrument equipped for this to work, right?

Right, I asked this before the update. I already found that the buff effect from both skills affects both skills. And no, you don't need to Rank 5 Song. I think you will get the bonus regardless of how high rank you are in either skill.

Using a Rank F skill, it appears it does stack. 15 from my r1 playing + 8 from enchants/upgrades and +11 from my current song rank (Rank 5) = 34
