Polyphonic: The LFO is generated to a slightly different frequency for all of the keys pressed.Monophonic: The LFO is in phase for all of the voices.Additionally, LFO 1 and 2 have different modes: LFO 3 has the first 4 waveforms and is activated with the modulation wheel and/or aftertouch. LFO 1 and 2 have 5 waveshapes: triangle, ramp up, ramp down, square and random with sample and hold. LFOs – There are three LFOs available.

There are controls for the feedback and mix too. If the delay is synced, the delay time knob controls the time division instead of the delay time. It is possible to sync the delay to the MIDI clock too. Delay – The delay can be a stereo delay or a ping pong delay, with its maximum delay time being as long as 1.35s.There are controls for rate, depth and mix. Each delay line has its own internal LFO. The Basic algorithm uses two delay lines, while the Ensemble uses 4 delay lines. The Basic algorithm is subtle and allows you to add some spatiality tothe resulting sound, while the Ensemble algorithm adds a different dimension to the sound, simulating a string or vocal ensemble. Chorus – There are two types of chorus available: basic and ensemble.It features keyboard tracking and it can be controlled by the modulation wheel or aftertouch. It can also be modulated with any of the 3 LFOs. It can be modulated with EG1, this modulation an also be affected by velocity. Filter – The filter is a 4-pole ladder-type low-pass filter with resonance control.Mixer – The mixer can control the levels and mix the two oscillators, the suboscillators and the white noise or the external input.All the voices are tuned in parallel, making a lot faster than usual. The autotuning algorithm takes about 2 seconds to complete. Its pulse width can be modulated with LFO1 and/or EG1. Each oscillator has a pulse wave that can be turned on or off, which is mixed with the other waveforms. Tuning can also be modulated with any of the three LFOs and EG1. There is a fine-tuning adjustment and a transpose option, allowing tune adjustment up to +/- 2 octaves. Each oscillator has 3 different waveforms: triangle, sawtooth and saw-tri (triangle+sawtooth).

The e7 is a 7-voice, 4-part multitimbral synthesizer that features a completely analog signal path, built-in effects, MPE support and more. GS Music has introduced the e7, a new desktop synth that they say is the first analog polyphonic synthesizer ever made in Argentina.
