HammerHead Rhythm Station 1.0 is the original software drum machine based on the Roland TR-909, which uses its own banks for samples, and if you want a different bank of drum sounds to use there is a program called ‘MakeBank’ supplied from which you create your own banks of drum sounds. HammerHead is a 16 event, 8 channel drum machine in which you can change the speed in bpm and the feel by adding shuffle.
