I decided to migrate from Improvements topic (guitar theme started somethere http://www.kvraudio.com/forum/viewtopic ... start=1305 and ended somethere http://www.kvraudio.com/forum/viewtopic ... start=1350) here.

I managed to improve my Zebra guitar (now it more convincing at low notes). It isn't polished yet, but sounds good. But I haven't reworked my body model still, so here is sample with gtrbody impulse response. The same flamenko as hakey used.

Now I want to design good body model, may be within the Zebra.

This sounds very similar to the "Spring" classical guitar I've been cooking up with Zebra.
Let me have the midi file so I can post a clip just for fun!

I think he followed the link from Hakey here

Cool, thanks!

Here's the clip:

Well, it sounds much dry_er, but seems that it's basically the same thing.

It is interesting! May be we used the same idea for the patch?
My patch basically consists of 2 parts: low-mid frequency part (additive synthesis in spectrablend) and mid-high frequency part (comb-filter-based Karplus-Strong algorithm). Also there is noise generator. Patch is need some tweaking though (especially hi-frequency part).

Also it is interesting that I experimented with adding inharmonic frequency content into the attack phase of the sound. And guitar sound transformed to piano sound! Adding detuned version of the same sound improved piano illusion. May be I'll experiment with it later.

I have done quite a few guitar patches using Zebra.
Here's a couple examples.
Zefal

Blue
http://www.box.net/s/72313dce191264edb889
They are available here.

Interesting because I've used a completely different approach

I used 2 oscs in GeoMorph mode pulse-sq... sync on, PWM on .. oscfx like (static) hypercomb and expander.. and a parallel comb module for the body... that's basically it.

I have a big problem with running out of mod matrix slots when attempting to physical model something.. like in this case as well

@mcnoone, interesting plectrum action

12 slots not enough for you?
I used only 2 or 3.

They are just perfect acoustic emus Guys!

Great!!!

Mc's Zefal is good for electric stuff.

Cheers

My new Zebra Acoustic Guitar model, inspired by http://www.ece.cmu.edu/research/publica ... 95-018.pdf waveguide synthesis.

No external processing (except limiter on masterbus), guitar body modelled with Zebra EQs.

There's an excellent electric distorted guitar patch by Michael in his Soliton bank. Leads -> The Ripper. I lost at least an hour last night playing and tweaking. Pentatonic in D and use that aftertouch!!

That sounds amazing!

Thanks for the preset! I'll definitely check it out asap!

...i don't own it ( yet !) but this undoubtely confirmed to me why zebra has the highest rate here at kvr

- amazing work of sound design !
- amazing instrument's versatility !

I think that decay is too fast.

Quick note about structure and how to adjust decay.

There are two lanes representing "horizontal mode" and 'vertical mode" string vibrations. Each have comb filter as vibrating string model. I think that second lane (vertical mode) has right decay, but may be it is need to make decay longer in the first lane (horizontal mode). For that it is need to set Comb1 Feedback higher, I think 70 is ok.

But short decay is sometimes good in terms of making mix clearer.
