This is the 288r being used as just a regular multi-tap delay. The Studio H DPO square wave going in to the 292e and then in to the 288r. There is a bit of FM from the left side oscillator which is having its frequency controlled by the 266e. The main pulses are from the 252e on stage 1 and 9 of the 16 step ring. The 0 tap on the 288r is the main sound with the timing adjusted so the 9 tap coincides closely with the 0 tap.
