[LMMS-devel] R: MIDI routing lost on project saving or loading (LMMS 0.4.8)

[<ins...@li...>]

Hi,

I am using Lmms with JACK (it is not JACK2 so I had to comment the jack kicking error) and it has midi-through port that you can use for internal midi routing in Lmms. Its state seems to be correctly saved.
The problem seems to be if you use directly the output port "kick" for example. I will have a look at source code because I am interested in midi routing too. Furthermore I am planning to include (for myself at least) midi channel support to be able to use multitimbral instruments: if I am not wrong midi input is only on one channel, I will check it out again to be sure about this. I tried some time ago but when attempting to do this it is easy to get segmentation faults.
I am not sure but if I will, I'll also take a look to a way of recording cc values, but I hope this is a feature someone is already working on.
Another related feature is very important in VeSTige: to be able to create a knob for any cc to be sent to the loaded Vsti; if I am not wrong it is not possible now.

Ogg: [LMMS-devel] MIDI routing lost on project saving or loading (LMMS	0.4.8)



Hello, everyone!
I was playing with drum synthesis, and I found the possibility of making internal MIDI signal routing very useful. It's possible to create a "trigger" intrument and make other intruments get triggered with it, which leads to easy layering of different synthesizers to create one desired intrument. Without copying and pasting notes all time :)

The problem is: almost everytime I save and load my project (which I do frequently due to audio dropouts) all MIDI routing is lost and I have to remake it.What's more weird, sometimes some connections are re-appearing after reload but it's totally random and it's unlikely to see all my routing loaded correctly.

Maybe this data is getting lost at loading projects? I've sent the project file I was working on.
The Kick trigger instrument is silent, it has MIDI output turned on.
Three other instuments should have MIDI input set to receive MIDI signals from Kick trigger.
I'am using LMMS 0.4.8 on Ubuntu 10.04 variant (ArtistX). I have compiled it from source (LMMS) and I'am curious if anybody also expiriences problems with this... And if anybody could help me to get this fixed.

I'd be happy to fix this bug by myself, but I know nothing about LMMS code, and I'am not very skilled at programming in C++. If someone could at least point me the right source files, I'd be happy to try my skills with fixing this.

Regards,
