Its not possible to browse/load or save a single sound, only kits.

Only delay is set per track. Other fx you have to place on tracks.
Example track 1 : fm machine and track 2 :reverb. (You can choose the input for the fx track: neighbour for reverb on track 1 , or input a/b for reverb on the external inputs.)

You must put a trigger on track 2 and adjust the adsr for the fx become active.

I hope this helps you out.

Monomachine is no analog4, different beast, takes more time to get under control, But the sound pallet of the monomachine is much larger than the a4.
