Sinus Plus 2.0 is the latest version of the freeware organ virtual instrument for Windows.
Iliadis Instruments claims Sinus Plus isn’t your typical Hammond B3 emulation, which I’d agree with.
However, denying the shared common lineage behind such a virtual instrument is hard. As with everything else from the developer, this is a free instrument, but it goes beyond the aims of a digital organ.
Sinus Plus functions primarily as an organ, first and foremost at least.

You’ve got the various drawbars and can coax sounds out to hit the notes of a home organ, transistor organ, or any other electronic instrument in the same vein.
However, it goes well beyond just using sine oscillators to approximate an organ.
When you look at the effects section, you’ve got vibrato and chorus, reverb, and a rotary speaker emulation. For the most part, these are your typical culprits when looking at an organ emulation.
Where Sinus Plus departs is the inclusion of phase distortion. Made popular by Casio’s CZ series of synths, you can push Sinus Plus well into some fun synth territory. It coaxes out glassy pads, warm brass sounds, fuzzy strings, and a fair bit more.
Of course, there are drawbacks, as there are with any instrument. The interface is a bit dense but easy enough to navigate.
That said, there is an even bigger elephant in the room, so to speak. Sinus Plus is Windows-only, which is fine; that’s nothing new in the world of freebies.
However, since this is a SynthMaker plugin, you’re restricted to 32-bit VST as the sole plugin format.
Now, it is certainly worth exploring Sinus Plus. Few instruments approach the same sort of timbre and combination of functionality.
I would advise you to temper your expectations. This is a wonderful free instrument, but you’ll need a 32-bit host, a bit bridge, or something along those lines to get it up and running.
Aside from that, I’d love to see a dedicated phase distortion synth by the developer in the future.
If you like organs, you might as well give Sinus Plus a shot. It goes above and beyond what you might expect from a normal Hammond B3.
