Been working on a jazz-ish arrangement for Silent Night, and have completed a first run of the sax, double bass, piano and drums. Piano will probably be removed as with my current accompaniment skill level (which is zero), doesn't seem to add to the arrangement, more likely a distraction.
Interestingly, I can't actually here the double bass on my speakers - this is a 2010 mbp. On my reference headphones though, they come through clear as day.
Does this mean the frequency response of the mac's speakers don't have much low frequency response? Ponder ponder.
