MPS – short for "Musical Parameter Synthesizer" – is a software synthesizer plug-in for Microsoft Windows (VST2/VST3/CLAP) and Apple macOS (VST2/VST3/AU/CLAP). It is written in native C++ code for high performance and low CPU consumption. The main features are:

  • Unconventional sound creation approach.
  • Fast & easy editing using just a few "musical" parameters.
  • Straightforward resizable user interface.
  • 64 voices polyphony.
  • Supports MTS-ESP by ODDSound dynamic micro-tuning.
  • Resizable user interface (not "N" version.).
  • MIDI Learn ‒ all parameters can be controlled by MIDI CC.
  • Plug-in supports Windows (32-bit and 64-bit) and macOS (64-bit).

The aim of MPS is to create sounds fast and easy using a small intuitive set of
without bothering about the technical details.

MPS is the collaborative work of Wolfgang Kraus @www.wkreativ.at (idea+GUI concept) and Björn aka Full Bucket (DSP+GUI+patch programming). Read more about the background of this project in the user manual.

First of all: I love the Fullbucket plugins! They are so professional and so good sounding.
I think, Björn Arlt is one of the greatest synth-plugin designers out there. Don't forget, no Synthmaker or else, just C++!
And that at no cost...wow!
I like the emulations very much because I'm a sucker for retro synths.
I like the other stuff too, but in some cases for e.g. MPS or The Qyooo I'm not a great fan of the GUIs.
MPS is, sorry, ugly and The Qyooo is to dark for my opinion. But if you want to change that, you only need a graphic editor and the free tool RessourceHacker and everything is possible.

There are hundreds of synths out there that offer much more sound control. But they all need skilled users and at least a lot of time to program. This one is the opposite: Get the sound you have in mind within seconds, as a number of synth-parameters is changed internally at the same time. Focus on playing your music! And indeed you can achieve a wide range of sounds from bass to pads and glockenspiel.

But be careful: The morph pad of this synth tempts to big movements between the four poles, but in fact even very small changes make a big difference.

The release behaves in an unusual way, but that's due to play ability: If you play a percussive sound and keep the key pressed, the sound will stop according to sustain-level zero and decay-time. But if you press a key and release it shortly after, a standard-synth's sound would continue according to release. That's a strange feeling when playing and the reason for limiting release-time to decay, which is more natural.

Try it, play it - vote for it! :-).

This one feels very limited in comparison to previous Full Bucket releases, and feels very much for a keyboard player... So... Me being a producer/sequencer and not a "musician" seems I'm not the audience for this one... 3 Stars from me, but, ModulAir is AMAZING!!! (as is everything else from Full Bucket) and so I'm giving a benefit of the doubt star as those who it's for, I'm sure it's great.

The circle matrix is confusing. You need to make the rectangle visible so it would give a hint that this matrix is actually a square, not a circle. At first I thought that the dot is not follows the cursor properly.

It seems that it is just a mixing between 4 oscilators. I was expecting it to be some kind of morphing. But it's a mixing between.

There could be OSC phase retrigger.

On spots between 2 OSCs you will have some phase issues which makes some notes sound noticeably louder or quieter. For example between STR and WOOD.

The STRING doesn't sound like string. Something between harmonica and string. Probably need more unison voices to be more like string.

I don't know what VIVID does. But seems that each OSC has it's own type. But also could be nice to have control over that. For example when you make vivid for Metal it ads tremolo. But no way you can control the speed of that tremolo.

The release. It seems it doesn't make good job on the percussive envelopes. With percussive envelope even on 10 of release it will be like 0.

Could had monophonic option.

Overall it's a nice concept. Maybe needs a little bit of upgrade.

Nice concept.

Really LIKE these sounds~! One thing I noticed is that when using a pre-made MIDI file I created, I'll choose an instrument such as a pad & then play with the track ball on the matrix - after a brief time there will be some "buildup" - the stuff that's been previously played will continue to resonate while the newer stuff is playing - causing an overbleed of sounds. Is there something i need to adjust/be aware of for this type of function?

You could lower the release time e.g. by turning down the Release parameter.

Hope this helps + Cheers.

Will it seems to be working better now, thx~! I'd like to figure out how to set that track ball on a particular course - or live perform & record to a separate track, Might be fun [-}.

Amazing plugin. You have just made my way to approach sound design so much more fun. You should have won the challenge. Thank you a bunch.
