10 Classic Roland TR-909 patterns
The Roland TR-909 is the drum machine of techno and house producers, but it was also used for many pop/dance hits.
From Wikipedia :
The Roland TR-909 Rhythm Composer is a partially analog, partially sample-based, drum machine introduced by the Japanese Roland Corporation in 1984.
The brainchild of Tadao Kikumoto, the engineer behind the Roland TB-303, it features a 16-step step sequencer and a drum kit that aimed for realism and cost-effectiveness.
It is fully programmable, and like its predecessor, the TR-808, it can store entire songs with multiple sections, as opposed to simply storing patterns.
It was the first MIDI-equipped drum machine. Around 10,000 units were produced.
