Great work, CookedChef and Cultr1! I like "Cascade Train" and "Pulsing Misery" a lot!
CookedChef, the rhythmic drive you set up is great! Like Cultr1 said, the syncopation creates a great effect where the music is almost lurching forward. Even when after I listened to it a few times, the bass line still caught me off gaurd. The unison in the bass at bars 7, 15, 23, and 31 seem a bit hollow, though. Maybe play around with moving one of the voices down an octave (to G0) or maybe up to Db2 or something to see if you like the sound of the thicker bass there—those bars are pretty important since they mark the end of the bass ostinato, so my ears the unison bass doesn't give the line enough power. Also, I really like the chromatic melody that you bring in at the end. My ear hears it going somewhere different from where you took it, but what you did works. Nevertheless, you might try playing around with the last few bars, like Cultr1 suggested. Personally, my ear wants to hear more E-Db-C action going on (this could also work really well if you decide to add a Db in the bass to give some ionian-phrygian flavor to the melody), but I'm sure whatever you settle on will be great.
Cultr1, this is really polished work! I love the effect with the oscillating bass volume. I suppose the next closest thing we might be able to get with dubstep in ORGmaker might be to have multiple instruments on the bass (like you do here), but to give them different volume patterns so that their dynamics phase in and out with each other. Who knows, might be something to try out next time.
A statement and question for Cultr1, though. The dropbox links to your stuff above ("City Lights," "Falling Water," "Off To Work") seem to be dead. Could you put them up on Mediafire, perhaps?
