What ' s the adds ? <| sep |> All of the sequencing and mixing was done in Reonise . Synths used for the whole album were Tunefish 4 , TAL Noisemaker , and Lokomotiv . Vocals were done on in Reaper with an AT 4033 CL . <| sep |> Okay , I didn ' t feel like rigorously spelling out the statement , but since I ' m getting retarded replies , here goes . Let a be a real number and let f and g be continuously differentiable functions defined on an interval containg a , such that the limit of fx and gx as x approaches a equals zero . Then the limit of fxgx as x approaches a equals the limit of f ' xg ' x as x approaches a , in which case it might be possible to give a concrete value to the naive undetermined expression 00 in this case .
