One of Alesis's first drum machines. With 49 sounds including 10 kicks, 7 snares and a complete ethnic set all of which are 16 bit samples this drum machine is a great bargain! Its partner in crime is the MMT-8 sequencer. But the HR-16 has its own sequencer with 100 patterns and 100 songs available. The drum tones can be tuned, have individual level controls for mixing, and there is 16 voice polyphony which means up to 16 drum tones can be used within a pattern. Patterns are programmed in either step or real-time. With external click inputs and Midi, the HR-16 is capable of integrating your older drum machines or sequencers with Midi systems!
