“Camel Audio’s Alchemy is great for manipulating samples and has become our favourite way to create interesting pitched build effects that have texture and movement.

"With your samples loaded, bring the Stretch parameter down to 0% to ‘freeze’ the sample and select an upward pitchbend amount of an octave, try any amount you like but an octave is a good place to start.

“You can now automate the position parameter so it sweeps through the sample and automate the pitchbend to raise the pitch... In Ableton, add a note the length of your required build and create a pitchbend across it via the envelopes box which is accessible by clicking the capital ‘E’ in the bottom-left corner of the clip display and selecting the pitchbend parameter. Now select the Position parameter in the automation lane – confusingly, it appears as ‘S1Start’ – and draw an automation sweep across the length of the region from low to high. And you’re done.Sidechaining the build and/or adding LFO pan or delay can sound great.”
