Analogue Systems RS-510e EMS Trapezoid Generator (Dual Bus)

The Trapezoid Generator module is made under license of the EMS and is a remake of the EMS envelope shaper known from VCS3, Synthi A and AKS. It is a very unique modulator which can be used as a trapeze or triangle shape LFO and/or a attack-hold-decay envelope generator. It's flexible, weird and totally different from an ADSR. For the real EMS feeling combine the 500e Filter with the 510 Trapezoid. Thanks to a new dual-bus concept, this circuit is fully compatible to Doepfer’s Eurorack standard.

The Trapezoid Generator has Attack, On, Decay, Off parameters. The "Off" parameter can determine a amount of time until the envelope can be re-triggered. A very short "off" time will make the unit loop, changing it into a LFO. VC of Decay time, Gate input and a manual trigger button.
Two signal outputs that can be adjusted in level in polarity with one common knob.
Additionally the module has an internal VCA which explains the Signal in- and output and is being controlled by the trapezoid signal.

The Dual Bus version of the RS-510e features two power connectors, meaning it can be directly connected to either an Analog Systems or a Doepfer modular system. – Adapters are no longer necessary.

Because of the different position of the mounting holes there will be a gap of 0.5HP (= 2.5 mm) when mounting an Analogue Systems module next to a Eurorack module. Take this into consideration when planning your system. Gaps can be covered with 1.5HP wide blank panels by Doepfer.
