Groove Machine Synth (GMS)

Groove Machine Synth is a multitimbral hybrid synthesizer based on the FL Studio Plugin of the same name.

To load/save presets tap the menu icon (upper right) and choose Presets List. You can download and share presets on the GMS Presets Thread.

Parameters

Groove Machine Synth has a dual-oscillator architecture. It can operate in Subtractive, FM, RM and Sync modes, making it the most flexible and powerful Synthesizer in FL Studio Mobile.

  • FILTER

    • Cutoff - Channel global filter cutoff frequency.
    • Res - Resonance.
    • Attack - Time taken to reach the filter cutoff value (the envelope will start from a minimum cutoff).
    • Decay - Time taken to return to a minimum cutoff value after key release.
    • Amount - Peak cutoff frequency reached.
    • Kbd - Keyboard tracking. The filter cutoff will track up and down with the note played. Higher notes having a higher cutoff frequency etc.
    • Kind (filter) - Switch between LP 12 (Low Pass, gentle curve 12 dB/Octave), LP 24 (Low Pass, steep curve 24 dB / Octave) & HP (HighPass).
  • OSCILLATOR - There are 2 independent oscillators. Many controls adjust B relative to A.

    • A / B (Oscillator waveshape) - Click to select from predefined shapes or load waveforms from the library. There are a lot and you should choose them by the way they sound. Explaining them really won't help you to choose one in advance other than you noticing there are classic Square, Saw, Sine waveforms.
    • Pitch B - Pitch of Oscillator B relative to Oscillator A, change in semitones.
    • Fine B - Pitch of Oscillator B relative to Oscillator A, change in cents.
    • Noise - Blend in White noise (hiss).
  • MODULATION - Use this to change the interaction between Oscillator A and B. You can change the Synthesis type here.

    • Amount - Amount of Sync (additive blend), FM (Frequency Modulation / pitch) or RM (Ring Modulation / volume).
    • Kind - Type of modulation between Oscillator B to A. Choose Sync (blend), FM (Frequency Modulation / pitch) or RM (Ring Modulation / volume)
    • Attack - Envelope of Oscillator B > A influence.
    • Decay - Envelope of Oscillator B > A influence.
    • Contour - Peak value or Oscillator B > A influence.
    • MW Dest - Target parameter for envelope Mod Wheel (on the Keyboard). Choose Filter. LFO. Oscillator Modulation.
    • PB Range - Envelope range. Choose 1, 2, 7 or 12 (Oct) Semitones.
    • MW Amount - Amount of Modulation Wheel applied to the Mod Wheel Destination.
  • LEVEL - Main volume and panning controls.

    • Level - Overall volume level.
    • Pan - Overall pan setting.
    • Attack - Time taken for the filter to reach the maximum level.
    • Decay - Time taken to go from the maximum level to the Sustain level.
    • Sustain - Level when the key is held.
    • Release - Time taken to fall from the Sustain level to zero when the key is released.
  • ENVELOPE GENERATOR - General purpose modulation envelope source that you can use to automate the available targets in GMS.

    • Contour - Envelope amount. At center there is no envelope applied. Increase it to add an envelope amount. Decrease it to add an envelope amount but in the opposite direction.
    • Attack - Time taken for the envelope to reach the maximum level.
    • Decay - Time taken to go from the maximum level to the Sustain level.
    • Sustain - Level when the key is held.
    • Release - Time taken to fall from the Sustain level to zero when the key is released.
    • Vel - Envelope amount increases for higher velocity notes.
    • Destination - Target parameter. Choose Filter, Oscillator modulation or Pitch.
  • LOW FREQUENCY OSCILLATOR - General purpose repeating waveform modulation source that you can use to automate the available targets in GMS.

    • Contour - LFO amount. At center there is no LFO applied. Increase it to add an LFO amount. Decrease it to add an LFO amount but in the opposite direction.
    • Shape - LFO shape. Sine, Saw or Square.
    • Destination - Target modulation parameter. Choose Filter, Oscillator or Pitch.
    • Rate - LFO speed synced to tempo.
  • VOICES - Oscillator voice effects.

    • Transpose - Transpose the pitch of the Oscillators in semitones.
    • Slide - Slide time.
    • Chorus Detune - Amount of detuning for the chorus effect.
    • Chorus Stereo - Stereo spread.
    • Mono - Monophonic voice mode (one note at a time, works well with slide notes).
    • Auto - Legato mode. A slide will only occur when you overlap more than one note..
    • Voices - Select 1 to 4 voices. 2 or more are required for the Chorus effect.
    • Scale - Spacing of notes in the Chorus. Flat (voices spaced around note pitch), Chord (voices spaced up 7 semitones/fifth), Octave (voices spaced up 12 semitones)..
  • FX - There are three identical Effects units in series 1 > 2 > 3. Each can be independently enabled/disabled with the switch on the lower left of the Module.

    • FX Kind - There are 10 effects these include:.
      • Dist - Distortion. X - Distortion amount. Y - Low pass filter cutoff frequency.
      • Flanger - Flanging. X - Depth. Y - Feedback.
      • Phaser - Phasing. X - Depth. Y - Feedback.
      • LPF - Low pass filtering. X - Low pass filter cutoff frequency. Y - Resonance amount.
      • HPF - High pass filtering. X - High pass filter cutoff frequency. Y - Resonance amount
      • Delay - Delay/Echo. X - Feedback amount (echo strength) Y - Echo filtering.
      • Reverb - Reverberation. X - Feedback. Y - Wet level (reverb amount).
      • Panner - Panning. X - Left/Right pan position. Y - Binaural effect level. Up/Down.
      • Ring modulation - X - Modulator frequency Y - Not used. Ring modulation multiplies the volume of the oscillators with a sine wave oscillator (FM-synthesis style).
      • VOX filter - X - A special 'Formant filter' that simulates vowel sounds (A,E,I,O,U). Y - Throat size...of the human voice.
    • LFO Rate - Low Frequency Automation speed. Choose from 1/4 bar to 8 Bars.
    • Amount - LFO multiplier, from 0 to 100% (top).
    • LFO Shape - LFO waveform shape.
    • Modulation X/Y - Each effect has a pair of unique performance X / Y parameters as described above.
