My favorite 2x LFO configurations would be:
Sample Level + Synth Level = cross fade
Synth Decay + Sample Hold = tail cross fade
Overdrive Level on 1 LFO with alternate Amp Level on the other LFO. Gives you drive and growl while taming the level of that effect.
For FX, well the ability to put a different LFO on Delay AND Reverb would be nice. I like doing weird stuff with LFO on the Delay time, would be nice to also automate the Delay filter in tandem. For now I’m just p-locking that filter in the FX track. But that is step length limited.
The list goes on and on.
Sure you could realtime record these parameters, but then they all just become parameter locks, and often my LFOs are slow go longer than 4 or even 8 bars. Plus, there is a finite amount of parameter locks.
Freely assignable LFOs a’la Machinedrum would be a worthy consolation.
