Hi.
I have to give a solid body to a drone sound I'm trying to patch, so I'm looking for the best way to obtain bass and sub-bass frequencies.
Any advice is really welcome.
Low frequencies
use resonant highpass filter set to low frequency and with decent amount of resonance,
or
take FM operator, set it octave or two below drones pitch, and feed it's FM input with the drone sound
or
take some morphing or spectral osc and pitch modulator with linear modulation (don't remember which one that was exactly
), feed oscs freq input thru modulator, feed modulation linear modulation input with drone, dial FM amount and oscs harmonic content to taste...
btw, HPF and FM stuff works nicely in combination
and of course, imagination is the only limit

just because you cannot imagine something that doesn't exclude it from reality.
Indeed, the HPF will cut away too low -unaudible?- signals, while the resonance amplifies signals just above that. Just like an LPF set to high cutoff frequency and resonance can make a high frequency 'whistle'...
