If there will be at least one set of normal instruments (piano, guitar (distortion, bass, ..., clean), drums, orchestral instruments (violins, flutes, ... ), than it will be good =)
I installed NI Kontakt, so i have some guitar samples (Prominy LPC Distortion guitar, clean guitar, V-Metal, etc.), many pienos, enough orchestral instruments.
But i can not find or combine good lead guitar sound (I use Linux Mint 17). I could make this sound in Windows, but Windows with time it works slower and slower. And in one good moment comes time to reinstall Windows. And with windows I need to reinstall many large (over 100 gb) libraries - they claim installation and registration.
So wariant to use LM17 and LMMS is much durable.
Also it's quit difficult to find good drums too.
So this is a little con.
Also it's not comfortable to work with paterns. If to remove pattern from music editor it removes at all. If to switch off a pattern in music editor, it begins to hinder (to overlapother patterns).
It is a con too.
Absence of freezing feels quite acute. I think that converting one track (track of one instrument) with effects on it (also it will be not bad to freeze track without effects in mixer, only with effects on the instrument itself). In large compositions, freezing would be wery useful.
Good-looking and simple to use interface - good side of this program.
The simpleness of settings like too.
Ability of LMMS to work with the quickly-working Jack server helps to superior by comfort working (tautology again) with other DAWs in Windows.
But this program, as i think, does not fit using in studio yet, because it has not ability to record sound and to work comfortly with patterns (It concedes, for example, to FL Studio).
Sorry for my bad english, thanks for good program =)
