Is there any good way to warp an agtr? It seems to add too many artifacts to this kind of sound.

don't warp with beat mode selected, try texture or something else instead.
Perhaps incremently re-rendering the sample source after long time stretches may help. as it will reset the "original" baseline (in terms of how the audio pulls away form the data source, relative to what Live warp engine is geared to whip up in realtime.) I haven't tried these tests out yet, because I am still struggling with rewiring to Logic, which raises another point, perhaps the new time/pitch au might solve this well.

My major point is that there are multiple warp algorithms in Live (AFAIK), and not just beat mode. Aside from this the Tiger AU might present a new option.

Good Luck, and if you figure out a great method, please post! I want to record some more classical for stock samples sometime soon. They are a never ending source of inspiration for me!

Warp is dependent on accurate timing, extremely so with the beats mode. LOFA's right, try the others.

Also, I'd make sure the warp markers are spot-on; my experience with Live has been that I need to adjust the start a tiny amount when recording guitar. And that timing is going to be just a little less precise than a sequenced synth. Unless you set markers to each individual pluck (waveform transient). That's kinda cheating though lol.

IIRC, the live lessons in the help menu feature a guitar, also check the interview w/ Avi Bortnick on the artists page - maybe these would be worth looking at.

Also, try recording at the highest sample rate you can. The more information available for time-stretching, the better the result will be.
This is unconfirmed information, but it seems to make sense.

if you're looking for a good effect, record while you are playing the clip on loop and scrub through it with warp marker movement and different sizes of clip length. you'll get lots of interesting effects and it is also a great way to make one static loop sound like a solo. i've used this on drums and guitars to good effect (imo ) andrew

With the accoustic gtr, when you warp it I imagine the problem is in Beats mode the sustained notes warble, and in Tones or Texture mode the attack transients get f***ed up too much.

I had this mix that I wanted to speed up from 113 to 123. None of the warp settings were giving decent results, so I came up with the idea of using separate Warp Modes on the top and bottom end.

1. Copy the audio file you want to 2 channels (either Session or Arrangement view).

2. Insert an EQ3 over each channel.

3. On the first track, switch OFF the mid and high bands of the EQ3 - this is now your low end track.

4. On the second track, switch OFF the low band of the EQ3 - this is now your high end.

5. Play the low end track by itself.

6. Switch the Warp Mode of the low end clip to Tones, and adjust the Grain Size parameter until you hear no burbling.

7. Play the high end by itself, set it's Warp mode to Beats, and adjust the Transients setting until you hear the best results.

8. Trigger both clips at once, either as a Scene or on the Arrange page, It should sound pretty smooth.

9. Tweak to taste and render to disk.

Using the EQ3's in their default setting with 48db slopes as a crossover network sounds pretty good to me... you can tune the "crossover point" to suit the source material as much as possible by making equal adjustments to the Freq Low parameter of both EQs.

awesome stuff pitchy
