morphing VST presets

[nofish]

I'm wondering if I can use Usine to morph between 2 VST presets from a synth.

Say I have preset A and preset B and then a slider which let's me gradually transition between the two.

possible ?

Thanks ethnix73.

I have looked into that thread.

Bear with me, my Usine knowledge is a bit rusted currently as I haven't done anything with it for quite some time.

Anyway, I figured here's the key sentence from that thread:

With the new vst params parameter, we can morph between two vst presets. I didn't noticed it!

Ok, I see the "params" inlet on a test-synth I've tried.
Have connected an Array to it.
Cranking the size parameter up, I can randomize the full VST preset.

Cool so far.

Now how to proceed ?

What I want to do finally:

Find a Synth patch I like, call it patch A.
Find another one, call it patch B.

Have a slider to morph between them:
Fully left: patch A, fully right: patch B

Ideally, as I'm using the VST version of Usine, have that slider automation parameter exposed to my host (Reaper) so I can automate it there.

Anyone care to give a little help ?

Thanks.

Hi nofish, here is one solution:

so you see the params array out of VST. the goal is to pick your first preset and store it's params to an array, here via the VarAffect
then pick the second preset, store as well to annother array. then a midi automatable mix fader between the two. so one is multiplied from 0 to 1 while during this time the other is multiplied from 1 to 0.
then we apply the morph result = summ of booth back to VST params IN, but only if we changed the mix fader, to allow us to change presets or params on the vst freely in order to assign them once it's ok.
not tested, but normally it works..
