Similar to the Oberheim SEM, "The VEM or Voice Expander Module provides the Core Element for a synthesizer voice. It is part of the Luna Modular CORE SYSTEM series. Designed to integrate into an existing Euro Modular synthesiszer system or as the core element. The VEM also provides an affordable polyphonic solution.The module is comprised of 3 sections;
VCO - Voltage Controlled Oscillator
VCF - Voltage Controlled Filter
VCA - Voltage Controlled Amplifier
This module has been designed to provide a standard synthesizer signal path. Both the VCO and VCF have a normalized output to allow isolation of each section for external use or processing to be returned back to the module through the Mix-Inputs.
Presented with minimal essential controls and with maximum control inputs. All inputs and outputs are direct and need an external attenuator if level control is required.
The absence of attenuators for the signal and control levels lowers costs and frees up valuable HP space. This design feature allows better use of space as attenuators can then be used for other signals.
The VCO is a full range oscillator sporting Saw and Pulse waveforms.
The VCF is a 2pole Multi-Pass filter with self-oscillation at high resonance.
The VCA is a clean and fast VCA with zero CV feed through.
This is the 'TYPE-1' module. This indicates the style of the module, 1 VCO, 1 VCF & 1 VCA."
