Many producers are quick to jump to processing their channels as opposed to getting the building blocks strong.
Take the time choosing filter slopes, envelope amounts and oscillator combinations and types to get the right result.
If your bass is sounding thin, for example, you can use a sine wave layer for some sub. Or even changing the filter slope to something more steep can give a deeper feel.
Filters are technically EQ’s so using high quality oscillators and filters you should be able to get solid results from the get go.
