Reason 4 Thor
Found this, might help =]
Also if your using Reason 4.0, Thor is an excellent tool for twisted bass.
Open Thor > Right click initilize patch > have 2 analog Osc's running(click the number 2,
to make it red).
Open a filter on filter 3, use combi for now. make sure + is selected.
On LFO 1 set it to sync, 3/16, no delay for now.
On the bottom set source - LFO1, and destination - Filter 3 Freq'. Fiddle with the amount
setting; you should be acheiving a steady wab wab wab.
Now experiment with different filters, LFO speeds, and different destinations.
When your're happy, play one solid note(that sounds good) for 8 bars. Export loop as wav.
Open NN-XT, and load the wav you've exported.
Keep fucking with it, till it's murder.
Hope this helps.
P.s when in thor, make sure decay and sustain are on full for the amp.. or at least near
full.
