“Massive Percussive Synths”! Our demos don’t overhype or cover up the content. Nearly every Mainroom Progressive/Electro producer has made, at least one, percussive drop track. Yes, you can grab a percussion sample and re-pitch it, but you don’t have the control that a deep synth like Massive gives you. Enter “Massive Percussive Synths”! This pack is designed with those huge festival drops in mind.
