VIDEO - Acoustic Bass PT.2

[Chandlerhimself]

Here is the 2nd part on acoustic bass synthesis. Check out the custom IR trick. You might be able to find some interesting uses for it outside of acoustic bass. I hope you find this useful.

Hm, what I don't get. You analyse one bass sample which is at exactly one specific pitch.
In the analysis result of the EQ I think I was able to see the fundamental and harmonic bumps of this one specific note.
So my guess is, when the sample would have been another note/pitch then the bumps (aka fundamental + harmonics) are on different positions. Think of you go an octave up. This means the eq applied on your instrument would have to change based on the note you play in MSF. The way you modelled it though is static, isn't it? Isn't this kind of conceptually not perfect?

That is correct. It isn't perfect, so you'll most likely have to adjust things yourself. If you have access to an acoustic bass(real or sampled) it will be more accurate if you play multiple keys up and down the bass. The reason I used the smoothing is too get rid of the "bumps". If you're trying to make an exact copy of a sound it's better to more detail and more notes. In this case I didn't want an exact copy, just something that was close to the acoustic bass sound.

The idea behind it is that the MSF model is just the string while the sample is the string + body. If you subtract the string it should leave you with the body. If the note changes the harmonics will change but the frequency response of the body won't. Of course a single note might not excite all the harmonics perfectly, so of course you are missing some information. If you can use multiple notes do that, but for the sake of the video I only used a single note. I hope that clears things up.

I've been thinking it would be cool to have a key-tracked EQ in the MSF generator where it moves the bands up and down depending on the note you've played.

At the moment, you can do it using multiple filter modules, but having it in a single module with visual feedback would be amazing. You would setup the curve, specify the base pitch, and let MSF do the rest.
