Sylfid-f2 is a VSTi / audio plugin that generates sounds by hitting "virtual strings" with "virtual hammers", computing the propagation of the waves on the strings, and converting them to sounds.

Two instances of Sylfid-f2: metallic and plastic

It is based on the same technology as Sylfid-f1 but doesn't have all the complex tuning options of Sylfid-f1. It has one single type of hammer, and the parameters are global to all the keys.

Sylfid-f2 doesn't use any samples: everything is computed in real time. This allows to create sounds that exhibit real-life properties like rich tones and long decays, without any samples, no loops and no reverb:

E2 24s sustain, no reverb
A1 24s sustain, no reverb

Another benefit of the simulation is that there are no discontinuities between the notes, or between different velocities.
The same note played at a higher velocity will have a different sound, with more harmonics, as you would expect with a real string:

C4 played at 4 different velocities, no reverb

The model used for the strings includes its material: from metallic to plastic. This changes the harmonics and tone:

Plastic - Metal


88 keys.
2 strings per key, a total of 176 strings, for a more natural and lush sound.
1 hammer per key.
damper as on a piano (sustain pedal.)

Sylfid-f2 is a VSTi plug-in available on Windows and Mac OSX.

The simulation is a CPU intensive process. Our technology is fast enough to compute the simulation in real-time, but a two cores CPU is recommended.
Sylfid-f2 is multithreaded: it uses all the available cores / CPUs of your computer.
Our technology is not based on "delay lines" as some other engines, here it's the real thing.
