“Add Layer” and “Remove Layer” buttons are actually zoom buttons
It seems that the four buttons in the top right change the sidebar. The one that’s currently selected is the second one. Here’s a picture of the third sidebar.
From the looks of it, you can change the icon and the sound. You can change the base note too. dB alteration (from the looks of it) is also possible. And for some odd reason you can change how the sample is panned. Oh yeah and you can change the sample rate (though 8232 looks like a pretty damn low sample rate). As far as I know, there is only one compatible sound format for samples: wav. You can play, stop, pause, and record the sample. I don’t know what color does. Looping the sample is also possible.
It’s odd because should samples be panned in the middle? If you panned your sample all the way to the left, and you decided that you wanted to pan it in the song to the right, -100 + 100=0. It would be panned in the middle. Which means in order to get free choice on panning, it should automatically be set to 0, so you can pan either way equally.
Note = Sample. Notessimo just raises/lowers the pitch of the sample for each note until you reach the next sample.
-100 = panned all the way to the left; +100 = panned all the way to the right. So if you panned your sample all the way to the left, and in the song you wanted to pan it to the right, the furthest you could possibly pan it to the right in the song would be the middle. The only way to get the full range of pan would be to set the sample pan to 0.
On a side note, that is strange. If you panned your sample to the left, then that would mean the range is -200 to 0. How do you pan -200?
