As a beginner, I find the available tools quite overwhelming. Could someone please guide me on which tool would be suitable for creating a drone sound? Thank you.
It all depends on exactly what type of drone sound you're going for.
Any sustained note is technically a drone..
The easiest synth to get stuck into is probably the Pulverisateur. Play a single sustained note on a loop, then play with the frequency section, as well as the modulation portion. It's also worth turning on oscillator 2 and playing with the tuning for Oscillator 1 for some really interesting pitch bendy/modulation sounds.
The envelope sections for the filter and amplitude will help you shape how the sound develops over time; attack is how long it takes to get from nothing to peak, decay is how long it takes to get from peak to sustain, sustain is the chosen amplitude/level for a sustained note, and release is the time it takes to get from sustain level to nothing once the note has been released.
