Well, to hear anything thru effects, you have to trig effect machine just like any other machine in MnM. Also, if you put only the first trig on track, you have to put Hold on 127, otherwise reverb (or anything else) will fade out pretty soon. But you have all of those things in manual, just read carefully. By the way, p-locks on effects can do wonders (depending on your style, of course), but, as always, try to experiment. Effects on Input buss are also valuable (my little Akai MPX8 pass thru effects in MnM, and is also sequenced by it).
