Granular synthesis?

I posted a question about this on an other thread already but then thought that this could spawn a discussion of it's own.
I have this idea that if OASYS would have sample start offset parameter that could set the starting point in milliseconds or samples instead of 1st to 8th preset points, then granular synthesis could be done relatively easily. Anyone have ideas or thoughts about this?

I'd much rather see a proper dedicated EXi for the job

With HD-1 I'd like to see even just basic bumps like an extra LFO or an extra envelope, or even just more than 2 oscillators (as per Korg arrangers LOL)

Yes, Granular EXi. That would be great!

I'm seeing the OASYS's true potential now in combining the engines, if the combi mode would allow the editing of programs it would be effectively a digital modular. It is frustating to see that we are so close to that kind of power, I can almost touch it.

I'm a bit envious to the Arturia Origin for their modular approach, of course Origin can not, or more properly, does not want to compete with the OASYS.

I wish that in addition to the program editing Korg would make interprogram modulation routings possible in combi mode. Of course much can be done already with tempo sync and careful timing, and Karma software can be used, but it can grow pretty complicated pretty fast.

Yes, that rather odd omission is very

indeed

I very much like the idea of more audio and/or modulation routing capabilities between things, even if it is just in the context of the pair of EXi instances in a single Program. It would great to even just be able to route audio from one to the other. LOL, if the channel for that could optionally be 'per voice', okay thats maybe asking a little too much

Anyway, I like the way Korg R&D are thinking and I am looking forward to seeing what they come up with next ... the quality and depth of the EXi to date have been awesome.

I wonder could the Oasys handle those suggestions...?
Is the processor capable of it?
Would it mean a total - complete OS overhaul...?

Peace

Could you give some examples, either descriptive or audio, of the sorts of things you mean and the sorts of ways you are experimenting with your OASYS. I have to confess to generally not understanding your posts as they seem quite theoretical, though they read very interesting.

It looks like you are into synthesis in a way the OASYS was not quite designed, yet are tapping into a potential that I for can't see but nevertheless find intriguing.

Actually, I'm a member of Forum IRCAM (http://forumnet.ircam.fr and http://forumnet.ircam.fr/?L=1), and (arguably disgracefully), although I have paid for full membership and the Forum Pass giving me access to all of their software for several years, I simply haven't had time to exploit their incredible capabilities yet (though there are some plans in that regard). But I know they have numerous advanced synthesis packages, and if you are not aware of them (though I suspect you are); then I highly recommend you check them out.

But I'd be delighted for some explanations, and/or audio examples if you had the time?

(Actually Dan asked me to give some mpp3 examples of SY77/SY99 AMF/RCM programs on a MOD-7 related thread which I hope to get to this weekend and post here, so I know how time consuming such a request can be).

I haven't got to it yet but I have the idea of routing two EXi:s in a program together via external patch cable. If I get it to work I will probably have a permanent patch from Indiv. Out 7/8 to Audio Input 3/4.

I agree whole-heartedly!

I think OASYS would handle that pretty easily, only thing that I think could cause problems is the latency if you route many programs in chain (not parallel). But I can live with that, it would probably be few milliseconds anyway.

I hope it's not my English.

I'll try to post more examples, did you have a look at my previous ones?

I also got a combi working that routes any program thru the STR-1 string model, acting similarly to a comb filter. But when splitting the keyboard to the programs, the STR-1 can be triggered with different notes than the program generating the sound, with interesting results.
I recorded quickly few examples, these are still crude but I like the sound.

I have drooled over many such packages, especially the graphical spectral manipulation software. But they all appear to be for Mac only.

And now, something completely different.
I'm forced to part with my OASYS for two weeks as we are traveling to Tokyo with my wife for our honeymoon.

Anyone have good suggestions for synthesizer related places to visit while we are there?
