Note Velocities Cut in half on MIDI import

[Elucid8]

I'm completely new to this forum, and this problem I'm having is the sole reason I've signed up.

Anyways, whenever I import any midi files into LMMS, all of the note velocities are halved. 100% goes to 50%, 75% goes to 37% and so on. This is a big problem because with the soundfont I'm using, the timbre of the instrument heavily depends on the velocity. There are a lot of crescendos and decrescendos, but they sound weak when all of the velocities are cut in half. I really want a quick way to double all of the note velocities so that I don't have to individually go through all 10000 of them.

@Elucid could you state your LMMS version please?

If your importing whole midi compositions to LMMS, copyright channels, and karaoke will effect the outcome of the import.
You can try turning up the gain on the instruments, that are being used to make up the differences. But this will not help with ghost notes(Notes with no volume at all.) made from the copyright protection.
If your recording the midi from your musical keyboard, turn up the key velocities from 63 to 127.
To do this open the the the soundfont instrument, and click midi then click custom velocities, change it from 63 to 127 then you get the full velocities from your keyboard while recording.

I am curious here, because i dont own a midi-keyb so the whole concept of velocity is not something i can enjoy.
As i understand, velocity need a piece of hardware (midi-keyb) that has at least to 'switches' one initiating and one terminal
Velocity would then be delta-time between the two switches activation.
This time is then 'translated' to volume
End result
The harder you hit a key the faster the attack and also the maximal volume. A quality known from some RL instruments, but definitively not all!
A real concert-piano would have it
A real mono-synth would not
Does the soundfont version (sf2) in lmms support this at all?

I looked in a midi-imported file, and the value of the BASE-velocity was 127, that does not leave room for any adjusted velocity -right?

Velocity is a basic parameter of MIDI Note On (and Off) commands, which must be supplied. Keyboards that don't have any velocity sensing just set it to a fixed value, normally 127 (full on). If you're recording in LMMS this can be converted to the "Custom base velocity" value set in SF2 Player.

But when you're importing an existing MIDI file you'd expect it just to take the Note On velocity values which are in that file without much messing about. Unfortunately what happened with a simple MIDI file I tried (using LMMS 1.1.3 on WIn7) was that most notes which have a velocity value of 120 (approx 94%) turn up in Piano Roll with Note Volume stated as approx 120%....but since the Note Volume goes from zero to 200% it looks like only 60%.

So I have no real idea what's going on and particularly not why full volume is 200% not 100%.

Sorry, that probably didn't help - Steve

@umcaruje I'm using 1.1.3
@muskibear The piano roll has a maximum volume of 200%, and I think that might have something to do with it.

I tried to change the base velocity on the sf2 player to 100. It sounds better, but still different from when I play it on another program. I'm content with it now, but I still wonder what in the world is happening to change the note velocity.

I notice when I import a midi file LMMS also sets up linked Automation tracks for volume and pan. The volume for the simple one I tried was set at 79% constant but I can't see from the midi file where it got that 79% from....but it may have something to do with it.
