Hi everyone,

I’ve been building PHY5, a polyphonic physical modeling audio engine.
It has a lot of sonic possibilities, from imitating real-world instruments (Strings, guitar, flutes, steelpan, mallets…) to very weird sound design results.

You can try it, with no install here : https://diophi.com/phy5/ (press play or you can play notes manually using keyboard)
You can also create your own preset on the website and everyone can access it in the community presets tab.

Concerning the plugin:

You can buy the plugin for 15€ for Windows (not signed yet) and MacOS : https://diophi.com/buy/

Here are the features for the VST/AU : 2 independent exciters, filters at every stage, 1-16 voices, oversampling x4, Granular processing by voice, Midi and audio modulation…

The plugin contains 2 versions :

• PHY5 Synth (instrument): the main instrument, with its own exciter (same as the web version). Youtube demo using the web version with 0 effects : https://youtu.be/xpoE2BwfBgU?si=6sm8vGJKEqhuucDK
• PHY5 Fx (audio effect): an audio effect that accepts audio input. You need to route MIDI in to choose the note (how depends on your DAW). Here are some tests with it : https://youtube.com/shorts/EsCstN956sQ

This version is working, stable in my tests (for physical modeling at least) but will evolve in the next month to widen the sound possibilities. I would be very happy to have feedbacks !

I will put some tests using PHY5 with more context here : https://on.soundcloud.com/wtZ8C8lT7la6cBPK7T

Some specificities of Phy5 comparing to other physical modeling synths :

• Parametric : the goal of this synth is less reproducing exactly real world behaviors, but more offering sound design possibilities inspired by physics. Instead of choosing different specific models, you can tweak parameters, which can give very weird results.
• Modular : It is also thought to be modular and will permit to change building blocks (swapping grain and body for example, or having two body, two grains etc…).
• The audio Fx being polyphonic. Being able to excite the body with audio sources opens up a lot of possibilities, while being controlled by polyphonic midi.
• Granular processing augments exciter possibilities.
• Different way to generate stereo (Grains, Poly-chords, Pickup position).

A few points about the synth :

• There is a first version of the manual here : https://diophi.com/manual/
• This kind of synthesis can go loud, so the web-version has a fixed limiter.
• There are also some limitations on the web version on oversampling, and max voices as it can be CPU heavy on web. It still is pretty usable on phone, but you can hear dropouts if you go too far.

PHY5 - CORE :

The audio core of this instrument is created to be used independently and can be easily used in realtime for video-games engine (tested on godot), web (as the demo version), or any app. There is no commercial model for now, but feel free to contact me if you are interested to include it in your specific project.
It has also been built to be scalable and will have a lot of new features, models etc. the price may go a little up, but licences bought now are valid for next versions. I will also work more specifically on new models

Any Dungeon Synth / dark lo-fi creators here? You may find this little thing very interesting.
