Find a vocal that runs alongside the 'up & down' scale which is then pinpointed by the start of the acid line as you bring that in and out - - this will feed and complement your structure so far... say erm.... "I am .... eternal" or summink not as cliched but with that kinda flow... if yer get me :cheese:

Plus I always find that the words from a vocal snippet can give me the idea for a title and the emotion with which to progress the track...

That beat needs variety too so you can develop some swing and will provide you with an idea basis for your next level of percussion...

I know what it's like when you get a strong loop going but it dominates your perception, thus making it difficult to feel what may fit in to the mix and provide progression... :;
