Aurora FM: FM synthesizer (VSTi, 32-/64-bit Windows)

Features:

  • 4-part multi-timbral FM synthesizer with 6 operators, 39 algorithms, 65 waveform variations, 64 voices, deep modulation, effects (overdrive, chorus, delay, and reverb), and performance features. A whopping 602 parameters per part.

  • High performance, 100% original C++ and assembly code with meticulously optimized execution paths for processors supporting SSE2, AVX, or AVX2+FMA instruction set extensions.

  • Single-screen, everything-visible, non-skeuomorphic UI with controls designed for efficient mouse interaction and visual feedback; no hidden parameters, tabs, menu-diving, etc.

  • Unique variable 2x3 or 3x2 operator layout elevates clarity and usability beyond other FM synthesizers.

  • DPI-aware and custom scaling from 50-200%.

  • ODDSound's MTS-ESP microtuning support.

  • Not a DX7 emulation - Aurora FM translates Yamaha DX7/21/27/100/11 & TX81Z patches but is a superior, semi-modular, highly-usable modern instrument for musicians and synthesists.

  • Inspired by modulation monsters like the Alesis Ion and Waldorf Q.

Details:

Architecture:

  • 4-part multi-timbral
    • 4 complete synthesis engine instances, each with channel, key range, voice limit, mute, and level.
    • plus Parallel reverb effect, with per-part pre/post-fader send.
  • Per-part 1x-4x oversampling.
  • Full 32-bit floating-point signal path.
  • Full-rate modulation.
  • High-resolution, fast approximate sine generators, with about 85dB average / 75dB worst case SNR. No look-up tables.
  • Execution paths for SSE2, AVX, or AVX2+FMA SIMD extensions.

Operators:

  • 65 combined waveform variants, which include the 8 sine and sine-transform waveforms found in the TX81Z and DX11, and many others:

    • 13 base waveforms, 5 waveform variants, and polarity.

    • Waveform Depth, interpolates between sine at 0% and the selected waveform at 100%; Moddable.

  • Independent per-operator feedback by self or any descendant modulated operator; Moddable.

  • 3 frequency selection modes - Ratio, Fixed, and the unique Relative mode which facilitates setting intervals.

  • Variable waveform sync phase (0°, 90°, 180°, 270°, None).

  • On/Off toggling with clear visual feedback.

  • Variable 2x3 or 3x2 algorithm-dependent operator layout with visual separation of modulators and carriers provides unparalleled clarity and navigation.

Envelopes:

  • 6 stages: Delay, Attack, Decay1, Decay2, Sustain, Release.

  • 9 slopes: 3 Logarithmic, Linear, and 5 Exponential.

  • Tempo-syncable.

  • Loopable.

Modulation Generators:

  • 2 x LFOs, 1 x S&H, 1 x Envelope.
  • Tempo-syncable.
  • 3 voicing modes: Mono Reset, Mono Run, Poly Reset
    • Monophonic mod sources are global and shared by all voices; Polyphonic mod sources are unique to each voice.
    • Reset/Run - Resets at each key-press / Free-running.
  • Amplitude scaling by ModWheel and a selectable mod source.
  • LFO1/2 selectable start phase (0°, 90°, 180°, 270°).

Modulation:

  • Operator pitch and amplitude modulation by 5 simultaneous modulation sources, with 3 modulation polarity modes and 3 convenient modulation ranges.
  • Additional operator amplitude scaling by Key and Velocity.
  • Envelope rate scaling by Key, Velocity (On + Off), and selectable modulation source.
  • 2 mod source slots for CC inputs (CTL1/CTL2).

  • Mod Matrix
    • 11-entry, with Destination, Source, Amount, and Polarity.
    • Destinations: Pan, Unison Detune, Feedback 1-6, Waveform Depth 1-6, Part Level, Reverb Send, LFO1/LFO2/S&H Rate, OD, Chorus Rate, Chorus Depth, Chorus Mix, Delay Level, and Delay Feedback.
    • Sources: LFO1, LFO2, S&H, Env, ModWheel, CTL1, CTL2, AT C, AT P, Random On/Off/Both, Key Lin, Key Exp, Vel On/Off/Both, Uni #.

Performance:

  • Polyphonic (64-voice), Poly Retrigger, Mono, and Mono Legato voice modes.

  • Unison with 2-4 voices and variable detune.

  • Portamento:

    • Normal and Legato modes.

    • Rate, Time, and Tempo Sync modes.

    • Time.

  • Pitch bend range, +/- 24 semitone Transpose, variable A440 tuning (+/- 1 semitone in 0.1 Hz increments).

  • Numerous alternate temperaments and non-traditional scales.

  • MTS-ESP microtuning support.

Effects:

  • Overdrive, 2 variations.

  • Chorus, 4 variations, tempo-syncable (Off/Alg1-4, Rate Mode, Rate, Depth, Dry:Wet Mix).

  • Delay, 4 variations, tempo-syncable (Mode, Time Mode, Time, Feedback, Level):

    • Stereo (2Ch), Mono (M), Stereo Ping-pong (P-P 2), Mono Ping-pong (P-P M).

  • Reverb (Time, Tone, Level).

  • Output bit-depth reduction, optional dithering.

This is the only product I have ever felt strongly enough about to review. I have messed arond with 200+ soft synths over the last 15 years. In my subjective opinion this is the best sounding soft synth that there is. The one negative is that preset manager isn't obvious. (Use the one in the middle of the screen, not the far left). Once you find the patch manager (which is there at the bottom) it should be straight forward to save patchs.

It's a hidden gem, FM synth for the 21 century. Despite the fact that there are quirks in the interface, designer did a very complex job to fit such a complex thing like FM synthesizer on one screen. So designing sounds is very fast unlike other FM synths on the market with many pages and menu diving.

Aurora can sound beautiful like a modern Montage and raw like a old 8 bit DX synth.

Randomizer is pure inspiration for new sounds.

Love it.

Aurora Fm is a great FM synth. Not your usual fm synth, there are a lot of subtilities to be found on that one. Feedback routing, Distinct waveform (and you can morph them back to sine wave), Modulations are really deep but everything is kept easy to access on a one page UI.

The sound quality is awesome, and you can set oversampling and dithering as you want if you in search for aliasy/lofi stuff.

If it isn't enough, you can add to that the 4 multiparts, all the algorythms you'll need and the nice effects.

A real workhorse to design sounds quickly and as precisely as you need and a real bargain.

On the con side Preset browser could be improved.

IMHO, Aurora FM is one of the very good sounding FM Software synthesizer that you could find in the market. I have been using it in many of my projects for the last 2 years, it has never disappointed me. Even in its raw form, I find the sounds from this synth to sit relaly well in most of my mixes. With a little bit of thrid party FX (Delay and Reverb to be specific), the sounds can be further improved. On my 3 years old laptop, this plugin does not eat up much resources (mostly in signle digits) even with multiple instances running.

Ryan (the developer behind this wonderful plugin) has been simply amazing with his constant mailers (no spamming) and important updates to the VST. He is also a very friendly developer who listens to the customer's suggestions on imporving the plugin.

I highly recommend this VST for anyones who is looking to add some fine FM goodness into their prodcution.

This Aurora FM synthesizer is really an extraordinary VST synth. I was trying to find a FM VSTi that could reproduce the same kind of elastic sounds as the Yamaha TX81Z I used to own. Like everyone I used Dexed for some time but it does not really deliver and then I slowly lost interest in FM... until I found the Aurora ! If you think all FM synths sound the same, just try to load the same sysex preset in Aurora and then in Dexed, and enjoy the difference. The sound is MUCH clearer and enjoyable in Aurora, it is obvious from the first note that the oscillators and coding are first-rate. Thank you very much for bringing this wonderful synth to us ! It is now one of my go-to vsti's along with Aalto and Chromaphone.

I love how it sounds, it can create very interesting moving sounds

But, I dont understand how I save my presets, i read the manual and still dont know. The devs needs to just add a save feature that works.

You click on the preset thingy in the middle of the GUI, not the one of the far left. When the one in the middle is clicked on, a list opens up. Down at the bottom is the patch manager. You go into it. There when you click save it opens up a window and you just select where you want to save. I just made a folder in the same place I have auroraFM. AuroraFM just scans that folder for any presets. Also these are really nice: https://yamahablackboxes.com/collection/yamaha-dx7-synthesizer/patches/
