Description
The “Roland Rhythm” TR-77 was Roland’s very first product, made in 1972. It generates its distinctive drum voices from what are called “tuned resonant” circuits consisting of a capacitor, coil and resistor – very simple! The patterns are preset rock, jazz and Latin styles with 1 & 2 bars. There are no user programmable patterns as there is no “memory” – the patterns are hardwired.
