The tape loops were of real acoustic jazz drum kits playing different style beats, with some additions to tracks such as bongos, clave, castanets, etc.

 released an electro-mechanical drum machine called the Sideman, which was the first ever commercially-produced drum machine. The Sideman was intended as a percussive accompaniment for the Wurlitzer organ range. The Sideman offered a choice of 12 electronically generated, predefined rhythm patterns with variable tempos. The sound source was a series of vacuum tubes which created 10 preset electronic drum sounds. The drum sounds were 'sequenced' by a rotating disc with metal contacts across its face, spaced in a certain pattern to generate parts of a particular rhythm. Combinations of these different sets of rhythms and drum sounds created popular rhythmic patterns of the day, e.g. waltzes, fox trots etc. These combinations were selected by a rotary knob on the top of the Sideman box. The tempo of the patterns was controlled by a slider that increased the speed of rotation of the disc. The Sideman had a panel of 10 buttons for manually triggering drum sounds, and a remote player to control the machine while playing from an organ keyboard. The Sideman was housed in a wooden cabinet that contained the sound generating circuitry, amplifier and speaker.

DIN Sync
The SYNC standard, often called "DIN sync" or "sync24" , defines an interface for electronic music instruments. It was introduced in the 1980s by Roland Corporation for synchronization of music sequencers, drum machines, arpeggiators and similar devices. The SYNC standard uses the signals clock ...

By the year 2000, standalone drum machines became much less common, being partly supplanted by general-purpose hardware samplers controlled by sequencers (built-in or external), software-based sequencing and sampling and the use of loops, and music workstation

Programming

Programming of drum machines are varied by the products. On most products, it can be done in real time: the user creates drum patterns by pressing the trigger pads as though a drum kit

 were being played; or using step-sequencing: the pattern is built up over time by adding individual sounds at certain points by placing them, as with the TR-808 and TR-909, along a 16-step bar. For example, a generic 4-on-the-floor dance pattern could be made by placing a closed high hat on the 3rd, 7th, 11th, and 15th steps, then a kick drum on the 1st, 5th, 9th, and 13th steps, and a clap or snare on the 5th and 13th. This pattern could be varied in a multitude of ways to obtain fills

If the drum machine has MIDI connectivity, then one could program the drum machine with a computer or another MIDI device.
