Multichannel VST Problem

[composerx]

I'm having a very unpleasant problem with multichannel VSTs.
Say I've made a blank project in Mu.Lab. I set up midi inputs, assign channels to midi tracks and load up a certain multichannel VST. Then, I choose patches for different midi channels in my VST and set Mu.Lab to "Use Automatic Midi Target". All is sweet until you try to switch to another rack. Once I switch, nothing happens, except I hear the instrument assigned to channel 1. Even setting the rack as midi target won't help. I have to choose a rack, then a corresponding midi track and set midi channel anew to make it work as it should... And so every time when I'm switching to another rack.
Also, some other multichannel VSTs won't remember the patches I chose when I open a saved project.

I'm not sure what you mean.

When you setup some MU.LAB tracks so they target the same multichannel VSTi, and you right-click the tracks to setup the effective MIDI channels on which they have to play that VSTi, then when you click a track or part, the proper target plugin is focussed on the proper MIDI channel.

Of course, if you click a rack containing a multichannel VSTi, then MU.LAB cannot know on which channel you want to play that VSTi. Clicking a rack makes that rack the target for MIDI input, on channel 1. I think this is logical, no?

Also, some other multichannel VSTs won't remember the patches I chose when I open a saved project.

It's the VST plugin's responsability to load/save its data.

Which VST plugin(s) are you talking about?

Thanks, the save/load problem was solved.

I connect multiple racks to one multichannel VST like this:
But I have to re-assign channel for a midi track (that targets a rack) every time I want to play thru it (it doesn't happen to a 'channel 1' track, though). I have only two multichannel VSTs (namely Hypersonic 2 and Edirol Orchestral) and this thing happens to both of them.

Question: Why do you need the racks before Orchestral?
What's in these racks? (just asking for my curiosity, it's perfectly ok to do so)

Anyway, if i have two tracks targetting the same rack, but i set track 1 to target channel 1, track 2 to target channel 2, then

when i click track 1 i'm effectively playing rack a, channel 1
when i click track 2 i'm effectively playing rack a, channel 2

I just tested this and it works ok.

So i still don't see the problem, sorry

Note that if you click a rack itself, then midi channel 1 will be used as MU.LAB cannot know that you would want to target another channel. So it's best to click the tracks or parts in this case.

Does this help?

...Well, for some reason I thought that

one rack = one midi track

I was wrong. Modular plugin area and Mu.Lab's interface in general was a bit confusing to me when I first saw it, so I made this mistake.
Thanks a lot! My problem is solved now

FYI: It could perfecty make sense to use racks before Orchestral in case you would want to apply some MIDI plugins (arp, chord-mapper, etc...) before the midi events get to Orchestral.

On top of that note that it is not necessary to use racks for that, you could also connect such midi plugs directly in the MPA.

You can see MU.LAB as a flexible music studio where you can play and experiment with connecting the cables between the various modules aka plugins
