Yamaha RX11
Yamaha's answer to the LinnDrum
Drum machine · Japan
The RX11 sampled acoustic drums at twelve bits with individual outputs and MIDI, and its dry, clean voices sit under a great deal of mid-1980s pop that wanted the Linn sound without the Linn.

Roland TR-505
Cheap sampled drums with a real sequencer
Drum machine · Japan
The 505 put PCM samples and the TR sequencer into a plastic box at a price that made it a first drum machine for a generation, and it turns up on more early house and hip-hop demos than its reputation suggests.
-
Boss DR-55 Dr. Rhythm
A programmable drum machine the size of a paperback
Drum machine · Japan
The DR-55 had four analogue voices and a sixteen-step grid programmed one instrument at a time, ran on a nine-volt battery, and cost almost nothing. For many players in 1980 it was the first machine they could actually program.
-
Roland CR-78 CompuRhythm
The first programmable Roland rhythm machine
Drum machine · Japan
The CR-78 kept the preset patterns of a rhythm box but let a player write four of their own and store them, which is the moment the drum machine stopped being an accompaniment appliance. Its soft, woody analogue voices open records by Blondie, Phil Collins, and Ultravox.
-
Yamaha RX5
Sampled drums a programmer could reshape
Drum machine · Japan
The RX5 gave each voice envelope, pitch, and filter editing plus cartridge expansion, which made it less a box of drums than a small percussion synthesizer.
-
Korg DDD-1
Sampled drums with cartridge expansion
Drum machine · Japan
The DDD-1 combined sampled voices with ROM cartridges that added more, plus per-voice outputs and tuning — a machine built for a studio that wanted to change its drum sounds without changing machines.
-
Roland TR-626
The 505's larger successor
Drum machine · Japan
The 626 widened the 505's sample set to thirty voices with Latin percussion included, and kept the same step-and-tap sequencer. It became a staple of home studios in the late 1980s.
-
Casio RZ-1
A cheap machine that could sample
Drum machine · Japan
The RZ-1 offered four seconds of sampling alongside its stock voices at a consumer price, which made user-sampled drums reachable years before that was normal.
-
Boss DR-110 Dr. Rhythm Graphic
The last of the analogue Dr. Rhythms
Drum machine · Japan
The DR-110 added an LCD grid that showed the pattern as you wrote it — the first drum machine many people saw their rhythm on — and was the last Boss box with analogue voices before samples took over.
-
Roland R-8 Human Rhythm Composer
Feel parameters on every hit
Drum machine · Japan
The R-8 let a programmer set nuance, velocity, decay, and tuning per step, and shipped a "human feel" function that varied them deliberately — an early, explicit attempt to answer the complaint that machines do not breathe.
-
Korg KR-55 Rhythm 55
Analogue preset rhythms with a warm voice
Drum machine · Japan
The KR-55 is a preset box rather than a programmable machine, but its analogue voices are soft and full enough that it is sampled and played straight far more than its category suggests.
