I love the sound of that MP3, love the sound of Marimba!

Cheers,

Shif.

good stuff luisi 🙂.... would you like to share the .osm?

Tom7777 · 31 Jul 2006

would you like to share the .osm?

Was just thinking that myself, this being in the examples area and all, hehe 😀

sambean · 31 Jul 2006

Sounds great, works fine here in Live.. And the demo is sweet!

Nice

Sam

Mmmhhh, chromatics 😀

I couldn't resist, here's my demo:

Song_126_02.ogg (2:41 | 3mb | q6 | CC by-nc-sa 2.5)

really nice plug to play with 🙂

currently this schematic isn't meant to be public, but maybe later, I hope you understand...

example? it is an example of a finished synth made in SM, <grin>

Very nice work.. 🙂 I understand your decision not to share the full schematic but would you be willing to give any details on how it works in a general way?

My Karplus experiments generated some mallet-like sounds so I'm curious what approach you've used.

i understand luigi 🙂 ..but i would be happy if you will do it 🙂 open source ..yay 🙂

thanks, any question is welcome, <grin>

for this synth and the harmonium I made (Peti), the approach was hybrid, using any useful synthesis, the basis is usually FM + subctractive, the envelopes and filters are the most important bits to shape the sound.

I use layering as well, a sound can be generated by two engines and then I add the outputs.

Physical modelling is used in these synths to create the acoustic feel, FM + subctractive lacks of liveness, so I use tuned resonators to animate the sound generated.

Is the physical modelling wave guide or karplus or something else? (If you don't mind saying.)

Sounds like quite the complex arrangement for so simple an interface. Now I'm even more impressed. 😮

Oh... and any chance you'd ever share a schematic on how you've made the tuned resonators? (Or even a reference on how you learned how to do it.)

I've done some stuff on this and got some wild results but they're so termpermental I've been reluctant to use them for a synth.

wave guide, simple delay with feedback thru a filter

that's typical of my synths, <grin>, I like to give a simple interface even though the synth is complex inside

may do an example as OSM, but they are really simple,

ok here is a screenshot of the Marimka Resonators internals, the filter on out is an HP, the others are LP

Ok luisi i understand 😀

luisi · 1 Aug 2006

good, the tricky part is to choose the the frequencies and the delays length so that it sounds nice,

also it should be added a crossfedback among the 3 lines, so to create a network

dreamkeeper · 1 Aug 2006

Sounds nice!

One question though: would it be possible to have the resonator in the poly section? The delay parameters could be key-tracked then, thus providing a nicely even response over the whole range. The way it is now, certain settings will lead to overpowering notes due to resonances. I guess, that's one of the reasons, you put a limiter in there? Just an idea...

Not with the stock delay component as they only accept mono input. (I haven't given it enough thought to say whether it's possible with coded delays.)

yes you can have the resonator in the poly section using coded delays, the sound will be different but not better, it's all it what you aim for E.G for steeldrums you want a mono resonantor

I thought so. It should be a modulatable (=fractional?) delay anyways, 'cause that's where the fun really starts. 😉 Should be possible with code I guess, although it'll be most likely a huge CPU hog.

Ah, ok! Thanks! I was just wondering...
