MIDI Input to VeSTige or ZynAddSubFX instruments?

Having trouble with LMMS? Ask about it here.
Hello LMMS Community,
I have my MIDI Keyboard connected to my laptop through a USB connector. I am able to control LMMS from my keyboard by associating my USB/Midi connector in the MIDI Input of my instruments. It works well with some .ogg files and most of the LMMS Instruments plugins but unfortunately it does not with VeSTige or ZynAddSubFX. I mean, I can associate to my USB/Midi connector but when I play the keyboard the green light to the right of the instrument name does not lit at all and no sound comes out.
Is there a limitation somewhere and if yes due to what?

Here is my configuration:

LMMS 0.4.14 - Windows XP SP3 - HP laptop - 3Gb RAM - USB to MIDI/In+Out connector - Korg SP300 Midi Keyboard
LMMS Edit / Settings / Midi shows only WinMM Midi.

Thanks a lot for your support
Christophe
I have heard there were some serious problems with 0.4.14 and MIDI. I don´t own a MIDI Keyboard myself, but I have seen guys on youtube playing with ZynAddSubFX, so I know it should work. This link is from the wiki and uses ZynAddSubFX as an example http://lmms.sourceforge.net/wiki/index. ... Using_MIDI

And you know you need to download files to get Sounfont Player and VeSTige to work, right? I am just checking every possibility :roll:

And again, it is wise to download the latest LMMS: https://sourceforge.net/projects/lmms/f ... ms/0.4.15/
Hello sti2nd and thank you to help me;
- I have downloaded and installed 0.4.15 and experience the same. I can open sf2 files, I hear them well but when I try to link them to a midi input and my USB to midi convertor I do not hear anything (and no green led blinking) when I play the keyboard. Same problem with VeSTige and ZynAddSubFX. No problem with .ogg instruments.
- I could not find the ZynAddSubFX example in the page that you referred to
- As for VeSTige and SF2, yes I have downloaded files and for SF2 I have opened them directly into B+B Editor and also linked them through Sf2 Player in Instruments Plugin and nothing works with Midi Input.
Do I need to activate something, a special setting? What am I doing wrong?
Any thought?
Thanks again
Christophe
