Audio: 1sec --> 10sec

How can I stretch a 1s Audio snippet into a 10s thing?

More to the point:
I'm having a sequencer that controls the pitch of an oscillator. Now I want to prolong only one note out of that row and make it sound longer, but without using another oscillator (which I think wouldn't be elegant) and - of course - without stopping the sequencer to constantly change the pitch of the (one and only) oscillator.

Thanks for any tips.

This is where I'm stuck: The loop captures the audio, but I don't know how to unfunny the sound. It either repeats itself or it doesn't sound like the original loop. I would like the audio capture to sound for e.g. 10 seconds.

I don't see what is so unelegant about using another oscillator/sequencer. I wish I could help, but I don't do much with the delay modules.

It wouldn't be only one oscillator but a couple of them. I'm programming a repetitive piece by Terry Riley and only a few notes need to be held longer than all other ones. I would have to build (well, copy and paste) a new "sound block" for each of the longer notes and think that would be a waste of resources. And wasting resources is unelegant Wink

OK, each to his own, but if the timbre is supposed to be the same, then I would imagine that notes artifically extended with the delay modules would sound different.

BTW, I'd be very interested in hearing your final version.

I'll send it to the forum, but it won't be tomorrow...

one of the things that always amazes me about the g2 is the ability to do very short and accurate durration events.

i think you might be better off trying to sample either one or a specific number of waveforms rather than trying to "capture the sound". if you are using specific pitches, this should be doable. you will want to start sampling at the begining of a waveform, and stop at the end (zero crossing detector)....at this point, you end up using the delay as a "digital oscilator" rather than a loop.

That's a cool idea and I'll try that in another patch. I got myself in trouble with routing all over the place so I organized the patch completely new and I will use extra oscillators now. It might me easier after all and I'm not sure if I'd really safe a lot trying to be elegant.
Thanks for your input and I will post the patch when I'm done.

i spent some time screwing around with this yesterday ( i didn't get far, but i learned a lot).

i'll post back if i come up with anything that actually works. in the end, however, it might be cheaper to use another oscillator (but less elegant of course).

Why not use an event sequencer freezes the note on a high logic signal, by using a sample and hold on the envelope gate and note signals? That way the sequencer keeps running while the note and gate data is sampled and held.

Just wanted to say that I posted the patch here:
http://electro-music.com/forum/post-55059.html#55059

There's a bug and maybe your ideas are just what I need. Thanks for that.
