Asper is an experimental synth combining wave table, subtractive, phase distortion and physical modeling for sound generation.

Idea was to add humanization to the sound on oscillator level in order to simulate behavior of real world instrument where each hit is different. It is not trying to simulate sound behavior like in analog synth, but rather to simulate Round Robin.

Instead of complex modulation I decided to split wavelet OSC to two layers that each has it's own control. This way is you can easily control (for example) attack per velocity without assigning any modulation source. You can detune each layer, enable comb filter, enable pitch envelope or phase distortion to each layer individually. All blending control have individual shape setting for each layer or even inverse mode in order to have different amount or phase while using same MIDI CC or velocity.
  • One wave table oscillator.
  • 118 wave tables that can be combined in multiple ways.
  • Comb filter for both wave table layers.
  • Advanced amplitude adjustment with break point control for better control.
  • Phase distortion for each wave table layer with 5 different shapes and it's own detune.
  • Mod section for Phase distortion with sync option.
  • One noise sub synth.
  • Round Robin simulation on oscillator level for both wave table and noise OSC.
  • Set blending mode based on velocity or control with assignable MIDI CC.
  • Ability to control shape for morphing, filter, FM amount starting from Exponential to Logarithmic.
  • Filter with parallel or serial mode.
  • Mod section for filter.
  • Shaper, two modes.
  • Saturation.
  • Portamento for mono with adjustable velocity level for triggering.
  • Vibrato module.
  • Interactive GUI with mouse over for each element that can be changed or adjusted.
  • Each control that have assignable MIDI CC have additional display for assigned controller.
  • All envelope controls have additional 6 quick sub presets to choose from.
  • Ensemble module for for unison or even reverb like simulation.
  • Simple soft clipper to prevent clipping that can be disabled.
  • Randomization for almost each subsection.
  • Simple preset manager.
  • One page with adjustable GUI scale, 80 up to 150%.

I would love to play with this beauty, but unluckily for me it’s windows only. Hopefully will be in future?? And if so, make sure it works on older Macs too, my Mac runs on High Sierra and can not be updated. Mac’s just run a long time :)

I'm interested in trying this, seems like a neat idea, any plans to make it an AU? Does it work on Apple at all?

Probably one of the best free synthesizer plugins I have used.

I think you just haven't played around with it enough, I've been producing for 4 years, and I think this plugin astonishing.

Bin zwar kein Synthi Nerd, aber dieses Teil ist kostenlos und erklärt seine Funktionen von selbst - hatte ich noch nie so schnell verstanden! Die Sounds sind 1.Klasse, die Bedienung ebenso..... Läuft unter Cubase 12 genauso Samplitude, Cakewalk und Mixbus32C-7 optimal Gut - Danke!!!

Wow! Just had a quick look, but I'm impressed so far! Mainly because of: VST2 in 32 (! ) and 64 bit :-) Built in preset manager (even if just simple). Really usabel randomize feature. Nice looking - and resizable - GUI with just one page. No crash so far with energyXT 3 in 32 bit and EXT64 in 64 bit. Good sound with interesting features. Thanks a lot!

This is a really interesting synth. I instantly created some really interesting and innovative textural and melodic sounds. I am a fan of creative/experimental synth approaches (Chimera, Subduer, Atlantis, Pendulate, Orca, Cygnus, Vital etc.). I really like how it was possible to make synths sounds more organic like a raw instrument. I did find that the GUI glitched a lot though and I had to open and close the plugin to access certain parameters due to the glitching. I will definitely keep using this but would love an update without GUI glitching.

A very flexible synth with a lot of potential. The controls are a bit flimsy and there is lot to learn. But anyways great sounding beast.

Wow! Just after a super-quick look at it, I'm loving several things about it: * 32+64 bit VST2! * 64 bit VST3 * Built-in preset management * Resizable * Beautiful GUI * Sensible randomize feature * Interesting, good sounds .

Wow, bester EnsembleEffekt, den ich je gehört habe! Dichte Flächen, Random-Buttons, tolle spacige Klänge, hat mich stundenlang animiert um Sounds zu basteln ...
