thank you for your answers, I gonna keep it
beerski : your advice seems so legit now that I listen again the song ! Since I used a kongdrum bass drum synthesizer
I will be able to tweak the bounce of the kick drum by reducing the decay and/or changing the tone.
guitfnky: yeah you're right, I should try to limit the sidechain compressor on the bass
moofi: thanks, I did a lot of ambient/downtempo tracks in the past and now I try to produce more "danceable" songs. But you're definitely right about trying new sounds, I learn Reason everyday, I find new way to create sounds. I never reused a synthesizer from a previous songs. In fact in this track, I use a synthesizer for all the hihat, I've never done this before.
