EMW-300 Synthesizer Voice Controller

The EML-300 was released as a controller or an expansion for the EML-200. It carries an aditional oscillator and has very interesting features that vastly expands the sound creation and controlling capabilties of the Model 200. Although the original EML-300 has not been designed as a stand-alone instrument, it can do a pretty good job in several situations, depending on the type of production being worked on. 

The good news is that the EMW-300 received an extra strength that allows it to be a more attractive machine in many cases because we implemented an automatic trigger to the Voltage Generator that turns this module into a 16-step analog sequencer. In some demo videos one might see it working alone but keep in mind that it really shines when acting in conjunction with other modular systems or more specifically with the EMW-200, of course. 

The Voltage Generator has 16 rotary knobs and 16 corresponding keys arranged in 4 lines with 4 controls each, the first upper-left knob corresponds to the first upper-left key and so on. Each rotary knob adjusts a voltage that appears on the Voltage and Sampled outputs when you press the corresponding key.

The Note Generator module contains a VCO with center frequency control and modulation input, an envelope generator with attack and decay controls, an internal oscillator with Rate, Pulse Width, and Range controls, a Switch to select between Manual or Auto note duration, and a start/stop push-button to control the Note Generator on automatic mode. There are two Envelope Outputs, two Gate Outputs, two main Outputs from the Note Generator, two VCO outputs (without envelope) and one Modulation input for the VCO. Also present on the back panel are an input for external trigger and a switch to select these two trigger modes (Internal/External) for the Automatic Note generator or sequencer.

The Manual Switch is a simple and useful module. It has two 2-way switch systems that allow the routing of any signal from the input to one of the outputs. It also has a 5 Volt pulse output that is controlled by a push-button (PULSE).
