this was the inspiration for ‘paul’ to make paulstretch btw, might be common knowlege, but also interesting. A 24 hour live streamed version of “Ludwig van Beethoven’s 9th symphony stretched to 24 hours, with no pitch distortions”
A cool trick I learned was with ableton’s reverb unit:
take a sound and put the reverb on with a very long decay time
set up a resampling channel,
play the sound and record it into the resampling channel
when the reverb is at a particularly nice sounding point hit the freeze button on the reverb unit and it will just stretch out that point in the reverb tail until you turn freeze back off
now in your resampling channel you will have a cool atmospheric drone sound that you can do whatever you want with
I like to whack it into a sampler and use it as a pad if the sound is an actual note, if it’s the reverb tail of a drum hit or something like that you can use it to make cool risers or white noise fills and stuff
