[Lmms-users] Uneven playback (Peter Schaffter)

[Stian Jørgensrud]

As I underestood it, Peter Schaffter, you connect MIDI signals from some
instruments in Musescore to the corresponding sf2 instruments in LMMS, and
then record from LMMS live output. LMMS is not made for live play, yet, and
only exports without missing notes, perfectly. It is widely known that it
sometimes skips some notes, and this is the way the core of the program is
built, so JACK wouldn't fix that, unfortunately. We have a vision to
rewrite the core of LMMS to be RT (Real Time) safe, but we either need a
good developer with a hell of a lot of time, or money to pay for one.

Exporting isn't an option because I'm not using the Song Editor.


But why? You only import the MIDI file produced by MuseScore, then it
appears in the Song Editor in LMMS (which you don't even have to touch),
and then export from LMMS. I reckon that combining audiofiles in Audacity
or some other free program shouldn't be a big problem for you. So the
question is, why don't you "use" the Song Editor?

Ah, this is probably the bit I've been missing: that LMMS is not
meant for live play. I've been assuming it was, based on my
experience with other samplers. If lmms isn't ready for live
play yet, then I'll have to wait until it is.

It's not so simple. If I export a Musescore score as .mid then
import it into lmms, every instrument is simply "sf2 player". I'd
have to load the sf2's for every one of 32 instruments, as well as
adding needed effects--again, for each instrument. And, of course,
the changes don't survive subsequent exports/imports, so I'd have to
repeat the process every time I made a change to the score (which,
during composition, might be hundreds of times). I'm not lazy,
but that would be an insane amount of work. Ultimately not
worth it, because I absolutely need live playback in order to test
dynamics in the score, tweak balances, adjust equalizations, etc.

I'm guessing LMMS was targetted from the beginning toward
composers who want to lay down midi tracks, not composers who write
scores. Unfortunately, I'm in the latter category. I can't even
begin to imagine how hard it would be to write complex counterpoint
using the Song Editor, plus there'd be no score or parts for real
musicians to play from.
