MX4 features a unique, hybrid synthesis engine that combines several forms of synthesis, including subtractive, wavetable, FM, AM and analog emulation.

MX4's basic synthesis architecture provides:

  • Unlimited voices, polyphony and instantiations (as many as your host computer allows).
  • Sample-accurate playback (with host applications that support this OS X feature).
  • Plug-in convenience - all settings are saved with host software projects for instant recall.
  • Modulatable effects - built-in chorus, phaser, flanger, reverb, and delay effects are integrated into MX4's modulation architecture and are saved as part of the patch.
  • Three wavetable oscillators - choose from over 90 wavetables with or without aliasing.
  • Audio input - process any audio signal with MX4's flexible synthesis engine in real time.
  • Modulatable waveform symmetry - create and automate dynamic changes in harmonics.
  • Oscillator sync - create hard sync effects, just like the legendary Sequential Circuits Prophet Five and other classic polysynths.
  • Frequency modulation (FM) - oscillator 3 serves as an FM source for oscillator 1, oscillator 2 and the filters.
  • Two resonant multimode filters - use low-pass, high-pass, band-pass and notch filters with 4 slope settings for a total of 16 different filter types. Create a wide variety of vintage keyboard sounds. Or stack both filters for 48dB per octave.
  • Variable Filter Topology - use 14 different filter and distortion configurations to produce over 3,000 different filter topologies, before you even begin tweaking filter parameters.
  • Six variable waveshape LFOs - each includes adjustable symmetry, rate delay, fade & phase.
  • Four DADSHR envelopes. Envelope time segments adjustable from 0 to 20 seconds.
  • Modulation sources - all continuously variable parameters, including LFOs and envelopes, can be modulated by many sources, including track automation, MIDI controllers, LFOs & envelopes. Simply choose a source from a menu and then option-click the MX4 knob or fader that you wish to control with it.
  • Open modulation architecture - each source can modulate an unlimited number of parameters simultaneously, providing the highest degree of programming flexibility possible. Conversely, any parameter can be simultaneously modulated by multiple sources.
