ES1

Apple

ES1 is a streamlined analog synthesizer emulator for Logic Pro that uses subtractive synthesis to create sounds by generating harmonically rich waveforms from its oscillator and sub-oscillator, then filtering and shaping them with flexible modulation options. It's designed for both beginners and experienced synthesists, excelling at punchy basses, atmospheric pads, biting leads, and sharp percussion through its intuitive interface.

Key Features

01Primary and sub-oscillator with sawtooth, triangle, square, pulse, and white-noise waveforms
02Four-slope lowpass filter: 24dB classic, 24dB fat, 12dB, and 18dB
03ADSR envelope generator with filter cutoff and amplifier modulation
04LFO with 5 waveform options: triangle, sawtooth, square, sample & hold, lagged random
05Modulation router with 7 target parameters and velocity sensitivity
06Three chorus modes: C1, C2, and Ensemble
07Polyphonic and legato monophonic voice modes
08Pitch bend with independent up/down range control

Things to Try

  • 01Set Cutoff to low, Resonance to high, and move ADSR via Vel arrows upward while striking notes to learn filter envelope modulation
  • 02Switch Sub knob to Off, drag Mix slider to bottom, and set Resonance to maximum to output a playable sine wave from the filter
  • 03Drag Form slider to positive value toward attack and select Pitch as LFO target with triangle waveform at ~5Hz to set up delayed vibrato
  • 04Set LFO Rate to 0 and use Int via Whl slider to manually control pulse width modulation with your keyboard modulation wheel
