Doepfer A-151 Quad Sequential Switch echo which can be arbitrarily increased

which can be arbitrarily increased with the chainable expander (see below)

Use one channel for adding stereo effects and the other to dial up some nice parallel compression

The result is this non cyclical vibrato/chorus/flanger-type thing favouring old tape flavours

a wavetable oscillator

Doepfer A-151 Quad Sequential Switch echo which can be arbitrarily increasedModule A 151 (Quad Sequential Switch) is like an electronic four position rotary switch. It includes trigger and reset inputs, four in outputs, and a common out input. Each time a pulse is received at the trigger input socket, the common out input is connected to the next in output. After the fourth in output, the next trigger makes it step back to the first again, and so on. A positive pulse at the reset input switches the out input immediately back
