Just came on here to post my new bass house track and was happy to see that you've done something new! Big fan.
You can try adding more colour to the piano to make it sound brighter. The way I do it is by applying Sausage Fattener (Free plugin by Dada life) to it and putting colour on full - it'll make it sound amazing.
Drop was insane, especially the second part of the loop (the higher octave/pitched part) you NEED to show me how to make that sound, or send me the preset or something - it's ****ing awesome and i've been looking for how to do it for agesssss.
One thing about the drop - drums: The kick sounds good but could cut through a tiiiiiny bit more - in fact no, leave the kick, layer on a "kick topper" like a click sound or another kick with lots of high freq's and cut out it's lows - just something to make the kick sound like it's sharper.
The clap and hats also sounds a little weak - try this (if you haven't already), make sure you compress each individual drum instrument. Low threshold, increase ration as appropriate then gain to recover lost volume. For sharp-hitting instruments (hats, snares, claps) increase the attack from the default (should be around 15ms default) anywhere up to 100ms - what ever sounds good. It will make them sound SHARP.
After this add ALL drums to a Drum Bus and compress that - not too much, just enough to bring all the percussions in tighter together.
Some may argue that you don't even need to do this, because overall the drums and percussions still sound good and aren't TOO weak.
Really good track mate, I'm about to post mine so check it out on the forum when its up - you'd be a really good person to give me feedback as this is my first bass house track.
Cheers!
