Hi everyone!

I've made 2 charts that translate the intuitive values from EG times and LFO frequency into "real" values.
There's something in the help file that looks more like a really small spreadsheet... I made a big nice graph so that you'll really know how long is a 45 worth on the good old ADSR.


you can find them on rapidshare at this link :

Cheers

P.S. : Both have algorithmic scales on the Y... google it if you don't understand

Hm - this links tell me, that maximum downloads (10) was reached before my request = no download-possibility for me any longer.

This link seems to be gone completely.

any chance of putting it on korgforums download page for oasys?

[Kayemef]

Oups... sorry, didn't know rapidshare was such a b&#ch with downloads...

I'll try to put ir on the downloads page.

[Kayemef]

Done, its been sent to the admin approval

[t_tangent]

Thanks Kayemef,

Look forward to using them when they are approved by admin

Much appreciated

I'll be updating the download section tomorrow.

I'm in the Studio here trying to get something done for a client who will be knocking on my door at 10am. lol.... shouldn't even be posting this. Must get back to work.

Sharp.

Sharp's real busy, so he kindly sent me the link to download the file on the server without having to go through the downloads section.

According to this, you could have an LFO modulate a parameter at 2kHz. I've tried modulating pitches with LFO in order to get something like FM, but at very high values I have a strange feeling that things aren't going exactly as they should under the hood...

Maybe I'm getting too technical, but there's something in Reaktor (and Csound if I remember correctly) called "control rates", in opposition to "sample rates". These control rates are usually much lower than the sample rates used to process audio. They usually, well, sample the control changes...

I was wondering if the O's "control rate" (or whatever its called - the thing that stores the data that represents the LFO) goes up to 2kHz... ?

bump bump...

Anyone at Korg might or might not know the answer to this ?

It's pretty anal on the details but I'm a curious cat

And btw, if anyone wonders how you can get an LFO at 2kHz, you just have to set the coarse and fine frequencies of the LFO at 99 - it makes it go at 32Hz. Then using AMS frequency mod at a maximum value multiplies the original frequency by 64. So 32 x 64 goes around 2kHz.

Try using it to do homemade FM or AM... its fun and surprising

Thanks Dan !

I do realize that the best way to do FM is to use, well, an FM synth engine

What's interesting is the fact that these simple LFOs can become very exotic/chaotic tools to create new sounds. Instead of have a classic vibrato assigned to the Y+ axis of the pitch bend joystick, you could have some sort of funky distorted tone changing thing going on...

I've also tried assigning a very, very fast pulse or sample and hold LFO to pitch variations of a few semitones, or even an octave. It gets that cool "SID chip" sound (the one from Internation Karate... aaaaah yeah).

Having that sort of flexibility shows just how much can be done with the Oasys... try doing that with a Fantom.... FACE
