With the SR16, Alesis has brought back a classic drum machine in a refreshed edition, featuring 233 stereo sounds that can be triggered using 12 velocity-sensitive pads. Each sample responds dynamically to the playing intensity, with adjustable pitch, volume, and tonal character based on attack velocity, offering a high degree of versatility and expression, while two footswitch inputs expand its functionality further, enabling hands-free control for triggering and performance flexibility. Whether it is used for songwriting or live performances, the SR16 will stand out as a reliable and adaptable tool for musicians of all kinds.
The Alesis SR16 drum machine is fully MIDI controllable, with the necessary IN and OUT/THRU connections conveniently located on the back of the unit, alongside the two footswitch inputs - one for sending start or stop commands, and the other for triggering variations and fills. Also on the rear panel is a stereo AUX output, ideal for tapping signals directly when using the SR16 for both speaker playback and recording. In addition to the headphone output, the unit features two stereo 6.35mm (1/4") main outputs and is powered by a 12V power supply, which is included in the package.
Thanks to its clear user interface, the Alesis SR16 allows patterns to be programmed quickly and easily with all of the essential data - such as preset or song name, quantisation, swing, click, tempo, and mode (record or play) - displayed on a single screen for a comprehensive overview of each pattern or song. Its compact size makes the SR16 a perfect fit for small home studios or live stages, offering convenient portability for any gig. Additionally, the SR16 gives users the option of loading patterns from data tapes via the tape in/out connections on the back, making it possible for nostalgic users to bring classic grooves back to life.
Alesis was founded in 1984 by Keith Barr in Hollywood, California, and has become one of the leading manufacturers of signal processors, drum machines, synthesizers, and other studio equipment. The company’s most successful products during its early years were the MIDIverb, the HR-16 drum machine, and the ADAT multitrack digital recorders. In 2001, Alesis was acquired by Numark owner Jack O’Donnell and is now part of his InMusic parent company alongside brands like AKAI, Denon, and many other well-known names in the audio manufacturing industry. Alesis has also been a major player in the field of e-drums for many years and offers a large choice of products in all price ranges.
The 50 preset patterns available on the Alesis SR16 were recorded unquantised by real drummers, delivering a natural feel that closely mimics live performance and is often hard to distinguish from hand-programmed beats; however, if tighter timing is preferred, it is also possible for all of the notes to be quantised. Each preset comes with variations and fills, allowing users to build full drum tracks for complete songs, while custom patterns, fills, and variations can also be programmed and saved with ease. The Copy function makes duplicating patterns or entire songs into new structures simple, and quick numeric entry on the display provides fast access to stored material. And as mentioned above, the tape in/out on the back allows patterns to be transferred to and from data tapes - bringing a vintage touch to a modern workflow for those who like a bit of nostalgia.
