Description

Here's what Behringer say about the 911A Dual Trigger Delay:

Modular Synthesis

The first System 55, 35 and 15 synth modules came out in the early 70s and tended to be extremely expensive. They were mainly all discrete transistor designs as op-amps at the time were very high cost. The discrete circuitry gave the modules a very distinctive sound and were used by artists like Keith Emerson, Stevie Wonder, Tangerine Dream and so many more, giving us some of the greatest records we’ve ever heard. Modular synths were a landmark development in electronic music and today, it’s about to get better.

911A DUAL TRIGGER DELAY

Enter the Behringer 911A DUAL TRIGGER DELAY. An authentic reproduction of the circuitry from the “Modular 55” series used by the world’s most famous pop, rock and jazz musicians. Now you can build your very own, unique synthesizer that can fit in a standard Eurorack case for a very affordable price. Mix and match with specific modules to customize your synth and complement the genre of music you play or go all out and have a room filled from floor to ceiling with modules that’ll fulfill any synth geek’s wildest dreams.

Controls

The 911A comes with two delay triggers with their own delay time controls ranging from 2 ms up to 10 seconds and their own 3.5 mm S-Trig ins and outs. Connect the 911A to the Behringer 911 ENVELOPE GENERATOR module and turn your Attack/Decay/Sustain/Release (ADSR) module into a Delay/Attack/Decay/Sustain/Release (DADSR) module. Rather than just playing the note when the signal is triggered, the 911A creates a nice volume swell effect, rising from 0 until the peak volume then going through the rest of the phases set in the envelope generator.
