@brasso , Axoloti is a lot of different things to a lot of different people
I do love your ideas, physically modelling is something I really enjoy !
you can get some ideas for what has already been done, is to take a look at the objects available in both the factory and community library.
my recommendation to anyone approach Axoloti, is to give it space to breath...
trying to replicate something else is more difficult that starting off my using what available, and then slowly over time (as you get more familiar) evolve it and create your own 'thing'.
basically not an issue, you need to decide if you want to go hardware or MIDI route, but both are well supported in Axo, scan the forum and you will see lots of interesting projects.
(checkout http://community.axoloti.com/c/your-music-projects, there are some there, which will I think really inspire you!)
Im dont keep up with the community library, but I think there are something in there...
KS is simple to implement...
Granular is also not that difficult (and definitely some of these in the
in 1.0.12 , Ive added a few things the may interest you :
LMNTS - based on the MI Elements module , see here, Ive also exposed some of its component parts like Resonator, tube, string etc... and its an area Id like continue to explore.
CLDS - based on MI Clds (see MI site) , includes granular looping into a resonator/verb
I do hope to build on these in future Axo releases, though no promises
Id raise a couple of caveats here... perhaps to 'manage expectations'
personally, I think Axoloti is about personal discovery, you will find lots of helpful people here in the community, creating all sorts of wonderful objects - but I think the most fun is had by rolling up your sleeves - and this of course takes some time, depending on your skills and the time you have will dictate how far you get. as I said, lots of helpful people to here to help you on your journey.
Kaivo, ok, your PC/Mac has a lot of computing power... a things like the waveguide modelling of Kaivo can be computationally expensive. I have Kaivo, and its uses a lot of CPU even on my Mac.
Axo is very efficient, it does have its limits... so getting massive numbers of voices doing the same techniques is unlikely - on the flip side, axoloti is cheap, so you can get multiple boards and split the processing perhaps.
its these last two points, which drives my initial statement...
the most fun Ive had with Axoloti, is just diving it, exploring ideas, and seeing where it takes me, rather than having a particular idea where im going.
