I bought the EHX tri parallel the other month for the same reason, to experiment with different setups. I like it so much it's made its way onto my pedal board. I'm using one channel to blend in some pork & pickle to thicken up my sound, another for the mono synth, and the third for octave & filter effects. For me, some effects work better in parallel, so this setup works a treat.
Have fun experimenting!
