With the e7, Argentinian manufacturer GS Music presents us with a 7-voice polyphonic analog synthesizer with subtractive sound generation. The desktop housing with its beautiful wooden side panels makes a high-quality impression and scores points with its screw-mounted controls. All the important parameters can be found on the tidy and well-structured control panel, allowing new sounds to be created almost automatically. Despite the familiar structure, the e7 is not a clone and impresses with a high-quality, independent sound. The OLED Display also functions as an oscilloscope and displays the waveform of the oscillators, the progression of the envelopes and the effects. The 512 presets, which can be overwritten at will, are joined by Panel Mode; as soon as this is activated, the sound corresponds to the current controller settings. GS Music has given the e7 four-fold multi-timbrality. For example, you can get three monophonic sounds and a four-part chord out of the instrument at the same time. Options for voice management, presets and even a mixer can be found in the menu. There are 128 dedicated memory locations for multi-programs. Thanks to full MIDI implementation, the e7 can be automated by any DAW or master sequencer. This also includes MPE MIDI with polyphonic aftertouch. Controllers such as Osmose, Seaboard or Continuum are ideal candidates to get the most out of the synth.
The voice architecture
One voice of the e7 consists of two identical oscillators that generate the sawtooth, sharktooth, triangle and square waveforms with PWM. Square can be combined with one of the other waveforms or used on its own. Each oscillator has a sub-oscillator that resonates one octave below the respective tone generator. Hardsync can be activated in the second oscillator. The fifth signal source is a noise generator, which can be replaced by an external signal via the audio input; all signal sources have their own level control in the mixer. This is followed by an excellent-sounding 24dB lowpass filter and the modulatable VCA. The two well-scaled ADSR envelopes are primarily assigned to the filter and VCA, envelope 1 appears again as a modulation source in the oscillators for Pitch and PWM. There are also three LFOs; LFO 1 and 2 each have 5 waveforms and offer six modes of operation, including Reset and clock sync. The third LFO has 4 waveforms, oscillates freely and is controlled via the modulation wheel or Aftertouch. Further parameters can be accessed via the shift function and the knob labels highlighted in white. The voices can be played polyphonically, polyphonically with dynamic voice distribution in the panorama, monophonically or Unisono.
Chorus and Delay for the final touch
The effects section shines with Chorus and Delay in various versions. All of them sound very balanced with plenty of retro charm and, above all, are easy to use. The chorus effect offers either Basic, which embeds the sound in slightly wafting weaves, or Ensemble, which is based on the string synthesizers of yesteryear. The delay effect offers Stereo or Ping-Pong, both with and without tempo synchronization. The Delay has a free-running delay range of 50ms to 1.35sec.
