This is something I've wanted to do for a long time but I've been lazy and felt it would be too hard to do. Now I'm on a mission to make it work.

Here's an example. Say we have some kind of a long noise sweep, and I want to morph from the sweep to some pluck lead. So the sweep would slowly start pulsating and the noise would become a clear plucking tone. And I'm not talking about mixing the two but true morphing.

Obviously some synths have morphing capabilities between "scenes" or whatever they are called depending on the synth. But I'd like to do this between any sound source.

It would be very cool to morph the sound throughout the whole track, what was a soft pad on the breakdown would become a banging lead, vocals turning in to bass, or whatever you could possibly think of.

Does anyone have any ideas how it could be done, or actually used such effect before? I'm going to try it tonight and possibly post some clips if it works.

I would probably have to get the second sound modulating the first one, slowly rising the modulation depth and fading the modulated sound so that in the end there's only the second sound left. Any effects that can do this? Could some kind of a vocoder work?

Ummm, I think your only options are to export both sounds to wave and crossfade, or automate all the knobs on the synth till it's a different sound.

I think this is what the flopped hartmann neuron synth tried to do.

Yeah, automating all the knobs works and that's definitely the way to go when working on one synth only.

But crossfading is not what I want, cause then you would simply hear both the sounds at the same time, and the only thing changing is their volume. The first one just fades away and the second one fades in, that's not morphing. What I'm trying to do is to have only one sound playing, that morphs into the other one.

Yeah, I've heard the Neuron wasn't all that good.. Maybe there's something similar in software? I use Chameleon 5000 and it can morph between sounds but you need a certain kind of a sound for it to work.

How does chameleon 'morph' between sounds exactly? All it probably does is crossfade the two patches slowly.

Or maybe not.. Maybe it actually moves all the knobs for you slowly untill it's the new sound you want.. That would be pretty cool.. but I would like to know exactly what it's doing when you say 'morph' between two patches.

Just use automation to change everything from patch A to patch B.

Holy shit!

There it is, with some googling:

It sounds so good it gives me shivers! Me gonna buy!
Check out the audio examples..especially this one of drum loop morphed to syhtetic choir:

That's what I'm talking about. And what could been found with a little bit more googling than I've done before..

wow I gotta try that thing!

I think I've just found my new favourite plugin

I think this is done using FFT algorithms to morph the harmonics of one sound into another. So its sort of similar to the way that some vocoders work, but a vocoder won't cover it, because all they do is take the spectral envelope of one track and mix it with the harmonics of another, the best you'll ever get here is a crossfade of those combinations of signals + the two dry signals.

What you want is a solution where both the spectral envelope and the harmonic content is morphed over time. This is done via FFT resynthesis, where the signal is analysed by breaking it down into a collection of sine waves, which you might be able to pull off in something like MAX/MSP or Kyma, which I think is how BT does it. But its hard and it takes a lot of CPU power. (And I could have been wrong about all of that just BTW)

Its good to see this plugin you've found though, looks like it might be what your wanting, but may not have the flexibility your after... Try looking at some MSP/SP/PD stuff maybe?

Thanks for the explanation! I'm gonna try the demo and see if it does what I want. From the audio examples it certainly seems so, I hope it just works as good as it sounds and has enough flexibility. I'm gonna look more into all this as it seems pretty interesting.

And as promised on the first post here is a clip. Only this was a lot easier than I thought Just made it in few minutes.
Simple bass sound morphs into a simple lead, no other effects used.
