MPS – short for "Musical Parameter Synthesizer" – is a software synthesizer plug-in for Microsoft Windows (VST) and Apple macOS (VST/AU). 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 user interface.
  • 64 voices polyphony.
  • MIDI Learn ‒ all parameters can be controlled by MIDI CC.
  • Double precision audio processing.
  • Plug-in supports Windows and macOS (32-bit and 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.

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 [-}.
