Running other instruments through Guitar Rig
1
You can use Guitar Rig to beef up a softsynth sound. Try placing a Dirt distortion on the rig with the Drive knobs cranked but the Mix down low. Then widen it out with a Choral and add a Large Hall RC 24 reverb on top.

There’s only one curated preset suggested with piano as the input source: Suitcase Piano, a cheap-sounding lo-fi effect. Use Guitar Rig’s reverbs to change the room setting of your piano and add choruses and Ensemble to easily turn electric.

Guitar Rig has plenty of options for bass guitar, especially as a tone shaper. Put a Pro Filter with a HiCut preset selected, a Solid EQ on Rock Bass setting and a VC 160 compressor with a Bass preset on. Use the Gate to cut noisy inputs.

Setting up Guitar Rig on an auxiliary bus lets you parallel process a vocal track. This is useful for EQing or compressing, or blending onboard effects into your dry signal. Distortion, Pitch and Modulation components can create modern hooks.
