I didn't have a lot to say here, except for this: If you're into free VSTs, and you don't yet have these; by all means download them. Rumour is that they're going to go 'pro' at some point, and as a result these will no longer be free. I haven't explored these in detail, but they have a unique sound all their own. The 3.x pack are all - more or less - software clones of top-of-the-line hardware from yesteryear. In general, these Modern effects have a much subtler sound than many of their free VST counterparts. Some of them - such as the Dynakiller ('limiter') are also capable of some really fine 'dirt' sounds. If you want to expand your studio effects palette, and arrive at place between 'sledgehammer-type' effects on the one hand, and something often barely discernible, these are the effects for you. That's a really long-winded way of saying, 'These VSTs rock! Make sure you get them!' Without having scratched the surface with these, Dynakiller in particular has found fairly substantial use in my 'studio.' It looks like the original offerings (which included Dynakiller and Painter) are in a separate, 3.x file; and the new offerings (which I'm downloading whilst typing this review) are in a separate file. This is all an extremely long-winded way of saying, "Download whatever this developer makes available to the public." I've sussed it out a bit. At this writing, the version 3.xx pack is all of the original VSTs, including Dynakiller and Painter. The new, 'fullpack4050' has the 7th Sign, Premier, and Flashverb. I can't wait to try these out. One more time: Get these if you don't have them already. They will definitely add more nuanced shades to your musical color pallette. It would be interesting to use nothing but these VSTs on a given collection (album) of songs, and see if the final result were painted with shades of the '70s era. Addressing documentation, presets, tech support, pricing, and stability: I haven't looked for any documentation; haven't used any presets; haven't needed tech support; didn't pay a dime; and they've never misbehaved as far as memory serves. Get these before they go $$!
It's done with Synthmaker as you can see at the end of the description of the present page. And Synthmaker/Flowstone will never be ported to 64-bit (the owners of the company don't want to port it to 64-bit, they have formally told it, and I guess that the challenge is probably as to try to reach the moon, seeing the huge slowness of that challenge for Synthedit, the other graphical environment of VST developments).
In addition Antress stopped his developments in 2011. 6 years ago.
mrbubs3, the sources are downloadable on archive.org though they are dropbox-links: Do it yourself (1.01) The Archive contains the .osm files, which are Synthmaker-Sources. I would rather try to convert them in Flowstone to 64-bit, since there seems to be this possibility available in Beta. Since Juice is a completely different environment, it would be a rather demanding task.
