!Roland TR-606

The TR-606 was an analogue drum machine made by Roland in the early 1980s. It's essentially a cut-down TR-808, with only seven of its sounds present, in simplified form.

The hi-hat has some useful quirks: triggering an open and closed hi-hat at the same time makes a different sound; and the tempo knob affects the open hi-hat's decay length, even if it's externally synced and otherwise ignoring the internal tempo.


The hi-hat's quite good on the 606, you can get quite good feels on it if you know what to do with the hi-hat, what hi-hat players would play, and of course Richard does.

— Chris Heaton, Landscape, 1982[5]

Technical notes

The TR-606 uses a 4-bit NEC μPD650 microprocessor, and two NEC μPD444s for a combined 2048 nibbles of RAM.[4]

It can trigger up to eight things at once, seven sounds and one accent: ACcent, Bass Drum, Snare Drum, Low Tom, High Tom, CYmbal, Open Hi-hat, and Closed Hi-hat. This suggests each position in the sequence uses 8 bits (2 nibbles). As with the TR-808, this means the one global accent is shared amongst all sounds at once.
