Thanks for the comments and complements.
I actually really like the choice for the drum beat. It gives a nice offset to the rest of the very mellow track. I just happen to like the sound of mellow pads with an energetic beat. I'm gonna rework the beat a bit and make it less repetitive. However, as for filtering it throughout... I tried it once and I wasn't particularly impressed with the feel.
I'll think about it with the recurring 6 note pattern. It's necessary, but I suppose it could be a little too repetitive as well. As for the flam snare, it might just need to be darkened... It stands out too much in the higher frequencies.
Lastly, the horn, if I bring up the higher frequencies too much, it sounds like a trumpet. That's completely not the sound I want. I want the dark sound of a French horn. But, I'll see what I can do and mess with the EQ on it a bit.
Huh, I wonder if adding a bassline in might help with the momentum, as you say?
