Step 1: Put the test oscillator on a track.
Step 2: Create only two automation points quite far apart from one another in time (like, a minute or two), one at the lowest allowed value (20Hz) and one at the highest (20kHz). If you like, use the automation curve tool to make a nice pretty sigmoid curve (see screenshot).
Step 3: Listen. The line on screen looks smooth, but it doesn't sound smooth. The sound jumps in jagged steps rather than transitioning smoothly.
These jagged transitions happen whether I use the automation curve tool or just a straight line. This also happens, for example, if I use a MIDI Modulator LFO on a slow setting. Or if I use a step sequencer automation row, set its step rate to something slow like half or whole notes, turn on only the step at the beginning of a pattern region and turn on the step at the other end, then set the row to "slide."
No matter what I try, I can't get a smooth automation; I can always hear the steps.
Sad trombone (or, more precisely: lack thereof).
I'm using the test oscillator as an example, but this seems to happen with just about any automation I try (a filter cutoff, release time, etc etc). Are long, smooth automations possible some other way? Must they always be rough? Is there something obvious I'm missing?
ETA: adding a project with 3 alternatives as illustration; you can clearly hear the "steps" in all 3:
- First alternative uses the drawn automation.
- Second alternative uses the MIDI modulator approach.
- Third alternative uses the step sequencer "slide" approach.
