The 606 was the percussion side-kick to the TB-303. It even looks like the 303. It stores up to 32 patterns and 8 songs.

Extended information

The 606 allows switching between Pattern Play and Write mode while running - making the 606 the only drumcomputer in the X0X series that can be edited while performing and switching patterns. It is also possible to link up to 4 consecutive patterns in Pattern Play mode. There is only a mono audio output.

The 606 has seven analog drum sounds which are simple, yet great! Kick, Snare, 2 toms, open hat, closed hat, cymbal, accent. The hi-hats are a very tinny electronic sound and its toms are great for soft tribal patterns.

For control, the 606 can receive or transmit DINSync for synchronization with other TR and TB family instruments. There are also two trig-outs on the unit, which make it very valuable as a pattern-programmable dual-channel trigger sequencer. It's often used for this by various people (Jimi Tenor) to 'drive' other sequencers and the like.
