Alesis SR16 Drum Machine
One of the most popular and beloved line of drum machines, and arguably a classic, the SR16 has been in production since 1991. The fact that it's thrived for all those years while undergoing nominal changes from year to year is a testament to its value. The user has 233 natural drum sounds to choose from of varying audio quality, both in dry form and with reverb. The Dynamic Articulation feature analyzes the velocity of the pad strike, and then chooses a version of the sample in question to trigger based on that velocity. In this drum machine there are 50 preset patterns that were programmed by drummers, which would seem to partly explain its popularity over the years. Lastly, the SR16 HAS MIDI In/Out functionality, and is capable of 16-voice polyphony.
