Does GarageBand have an oscillator/waveform generator like other DAWs such as FL Studio or Cubase?
I'm basically trying to create my own waveforms (to create bass, pads, chords, etc) from scracth, which you usually do using subtractive synthesis (e.g. with an oscillator).
I can't believe GarageBand would lack this key feature, so I'm pretty sure it's just sitting there somewhere waiting for me to find it.
Edit:
Platform: GarageBand for Mac (macOS 12.1 Monterey)
Note: The "Alchemy Synth" version of GarageBand for Mac lacks the Synth/waveform generator feature (which is the exact feature i'm looking for); it just allows you to apply presets to existing sounds
Here are some examples from other DAWs of what I'm looking for:
