Hi @3DC !
Thanks for bringing up this question and sorry for the confusion.
It is two versions of HALion but sold in three bundles, including two new instrument libraries.
The looong version:
These are the plug-ins, in plain english
HALion 7: The well known and incredibly powerful instrument and sound design environment, we all love.
HALion Sonic 7: The beloved player for instrument libraries with performance features for layering, splitting, mapping and scene/preset jumping. HALion Sonic 7 is FREE and replaces HALion Sonic SE. HALion Sonic 7 has more features then HALIon Sonic SE regarding live performance and layering abilities.
We also created two new VST Sound instruments running INSIDE the free HALion Sonic 7.
These instruments are available seperately or in the bundles mentioned below:
FM LAB: A fully featured FM Synth, with the ability to create your own sounds and a great library of presets.
TALES: An amazing hybrid instrument of a deep sampled open tuned guitar and synth layers.
So which bundle (called versions on our comparison website) should I get?
HALion Sonic 7: The free(!) plugin, without any content. But even without anything, it is a functional subtractive synth (so what are you waiting for, check it out, it’s free!). It can load all existing VST Sound content, released for HALion Sonic and HALion Sonic SE, if you already own a license for that content.
HALion Sonic Collection: This is really a packed bundle of exquisite content. Since HALion Sonic 7 is free, you essentially pay for a collection of VST Sound instruments, that should leave not much to be desired (covers anything from electronic to classical styles, rythm, texture, melodies) For those who own the full HALion Sonic 3, It also contains the NEW FMLab (full fm synth capabilites) and TALES instruments, which run inside HALion Sonic 7! So if all you want is play and get your hands on these instruments, get the collection and run it in HALion Sonic 7.
HALion 7: Get this if you want to go DEEP into sounddesign and instrument development. It contains all the content included in the HALion Sonic 7 Collection in ADDITION to the Sound Design environment. So, you do NOT need to buy HALion Sonic Collection, if you buy HALion 7. Basically, you get HALion 7 with the Collection library thrown into the package, which is a great deal imho.
