ASM Hydrasynth Keyboard

The sound engine is designed for maximum flexibility. At the same time, we designed the user interface in a way to allow you to edit the patch quickly with a minimal amount of paging and many workflow shortcuts.​

8 Voice Advanced Wavetable synthesis

2 Wavemorphing Oscillators

219 single cycle waveforms

• User wavetables - 8 user selectable ‘wavelist’ per osc to build user wavetables
• Every osc and patch can have its own user wavetable
• WaveScan parameter for modulating through wavetables.
• Keytracking – 0-200%
• +/- 3 octave tuning range

1 fixed Wave OSC

• 219 single cycle waveforms
• +/- 3 octave tuning range
• Keytracking – 0-200%

Dual Mutators per oscillator

• FM – Linear FM
  • Selectable Modulator source
    • Built in Sine & Triangle, OSC1, OSC2, OSC3, Mutators A, B, C, D, Noise gen, Ring Mod, External Mod 1&2 input.
• WaveStack – Generates 5 detuned waves from input source. Detune amount.
• Pulse Width Mod – Adjust pulse width of ALL waveforms.
• PWSqueeze – Compresses the center section of the waveform. Differnnt type of PWM
• PW-ASM – 8 User adjustable wave squeeze/stretch points.
• Hard Sync – gives that classic sync sweep sound.
  • Selectable Sync input source.
• Harmonic Sweep – will scan through the harmonics of the incoming sound.
• Dry/Wet mix to blend the original OSC source.

Noise Generator

• White, Pink, Brown noise sources

Ring modulator

• Selectable input sources
  • OSC1, OSC2, OSC3, Noise, All Mutator outputs, External Mod ½ in.
• Depth control

Sound source mixer

• Mix the following sources - OSC1, OSC2, OSC3, Noise, and Ring Mod.
• Panning for each source
• Filter routing mix
• Solos for each source (solo status is saved in the patch)

Two Filters

• Series or parallel routing
• Filter 1
  • 12 & 24db modern ladder (compensated)
  • 12 & 24db vintage ladder (uncompensated)
  • Threeler HP, LP
  • MS20 HP, LP
  • Low Pass Gate
  • Vocal filter
    • Multiple vowel order parameter
    • Formant parameter
