I think it would be great to change the name of Buffer Length to either replace or add the word Latency.
On the forum (and in other software), we always talk about lantency, while in OpenMPT its called Buffer Length.
In addition, it would be great to have somekind of explaination there what it does. Perhaps a [?] button or just a tooltip.
The text should say: Use this setting to determine how much sound is being buffered before its being played. A larger setting will generate more stable sound, but it will add a delay. Try to keep this setting as small as possible, without getting deformed sound.
Maybe a mention about the sounddevice.
Declined, since this is not the latency, but indeed the length of the sound buffer. Latency is just a consequence of the buffer length, but not the same thing at all!
