Notes won't play in piano roll

Having trouble with LMMS? Ask about it here.
I click em, they work. I click play in the piano roll, they don't make a sound. I play the project, it works normally. Is there any solution that can be put in layman's terms?

Edit: I checked again. Apparently, some things play and some things don't play. The heck?

Ok i read this as inside piano-roll:
If you left-mouse-click on the white and black keys, you have sound!
Right?
If you place a note in the grid, that note is silent
Right?

My guess is that you have set the velosity to zero, by accident, and use 'last-note' as note-setting.
That will remove the sound from actual green-notes, but still make sound on the keys.
Check if the velocity is all down in the lover panel in piano-roll, the bars seen here:

should default be 100%. In the picture the second is.

Ok
I believe that the black ryvius refers to the bug (if it is one) present in lmms 1.1.3.

For some reason, when I press play in the piano-roll, sometimes there is no sound coming out of the speakers. This also happens when the track is in solo mode. Of course, it's not related to velocity or volume. I believe it's a bug.

Is the bug also present in RC6?

There has been a 'bug' where muted BB-lines, could cause muting of a track in song-editor, but afair it was solved in 1.1

I do not know, I am still on version 1.1.3.
Maybe we are talking about the same "bug".
I never noticed the link with the BB tracks muted.
This happens in piano-roll, whether in the BB Editor or in the Song Editor.

What the balck ryvius describes reminds me of this "bug".
But maybe he's talking about something else?
D.ipsum is completely correct. That's the bug I'm talking about.

D.ipsum is completely correct.
So you are on 1.1.3?
I recommend that you update. REM : make a backup first!
I have encountered that bug, a few times in 1.1.3.
But unfortunately, I can't remember how to solve it. :P
