Working with the Elektron Octatrack has gotten back into sampling big time. Some of the things you can do with an Octatrack - like per step automation - can also be done with Ableton Push when working in "Note" mode in drum racks.
- One you turn on a note in the step sequencer, you can then hold the note down to acces all sort of parameters for devices. While holding the step...
- Adjust params to your liking. In this example I'm changing the pitch of each step in the step-sequencer.
You can of course record real-time automation by simply pressing the "Automation" button when in record or overdub mode.
Below is an example audio snippet I put on soundcloud of doing such that. I sampled audio from random needle drops on vinyl into clips and used them to build a custom drum rack. I then improvised using Push to perform and sequence these clips including per step automation of various parameters.
