Hi,
for the use of standart stm mixer and Mackie Control, I've created a little VSTi that don't output any sound, but only MIDI data.
I've played wiith it with success :
I create a midi track, load my VSTi in the VSTi rack, then select my VSTi as MIDI INPUT" for this MIDI track, and the pulsar midi out as output.
In the cubase pref, in "midi" tab, I check the case "MIDI recorded datas goes to automation only", to prevent cubase to put my knob mouvment into the MIDI track itself. This is to keep the benefit of the different mode of writing automation (autolatch..) and to prevent midi loops if I tweak parameter directly onto the sfp mixer.
what is great is that: parameter in the vsti are named as the corresponding param in sfp mixer, so when you click the instrument edit on your mackie, you see on the lcd the names of the parameters

and you will be abble to edit your sfp parameter from knobs inside cubase too.
the limitation is that the "read" + "write" mode (writing from the MCu or mixer, reading recorded automation), will be only possible using a Plogue Bidule patch I've done beside (Bidule will be running in the same time, the demo version I have don't get the vst version, so I can not define if it will possible to use this patch inside cubase)
but if you 're sure you won't never tweak a parameter that is already recorded in cubase, you won't need the bidule thing.
the other great thing is that you will be abble to use your MCU as usual for cubase edit/parameter tweak control...
there is other config step in sfp I will explain later (some midi routing devices to swith to bidule input/ouput in R+W mode),
this post is just to ask you, as we are limited to 128 parameter, wich one you want to see in the final release of this VSTi, for the stm2448. (will work so for the smaller mixer)
a workaround about the midi channels limitation would be to use more than one sfp mixer (eg one only for the volume and insert) and a second in serial connection (using the direct out) for the aux and master section. (if you split "parallel" we will loose phase comp)
?
that will work for the WOLF mixer too, but you will lose the possibility to drive the aux with pitch bend. but as Wolf mixer support midi multichannel and get high res PB for volume, I recommend you this one, a dedicated vsti will be done too (for the will my vsti is a channnel strip of the wolf mixer,)
so..let me know
if you want the vsti for a particular plug,let me know too, as the patching is done, it's just about renaming parameters inside the vsti.
I forgot: SynthEdit sound really well when you use it only for midi datas
