Sorry to write such a longwinded reply to the thread.
I honestly would love to check this out. It sounds like some very worthwhile goals are being reached here.
Is the manual on the website up-to-the-minute updated?
I'll say that without seeing and understanding more about the full features, such as via a 30 minute overview demo vid, its hard to make a decision. It appears that there are so many features that such a video would require a "start-from-scratch" approach, showing the most polished FX the plugin can produce, and then explaining how they are done. Can this be played live? Or is it meant only to play existing MIDI tracks and sequences? Is there a "trigger mode" similar to Omnisphere's Live toolset (Latch & Trigger are both permitted?) Even fully updated online manual would help, with a concise set of statements such as - "this is what I want to do that can't be done anywhere else, and this is how I can do it".
I empathize with the project. Because the plugin sidechains MIDI (which may be the best way to truly distinguish it in the developer's mind) it is really unfortunate that this really opens up a can of worms in my mind - because side-chaining is one of the more difficult things to learn with some plugins (basically because of the variety of DAWs that handle it somewhat or very differently - which is why I had issues with Fab Filter's compressor In Reaper but not in FL Studio for instance). So inevitably this is making me think, OMG how complex is this going to be.
I am unsure if this is for me because I've done a lot of experimenting tools that are cutting edge. The biggest example is Amaranth Audio, which reached a point immediately after I bought it for $150, where it ceased to be developed. There are creative MIDI and Arp related products that I already own, like the aforementioned Omnisphere (with Live Mode), Scaler, Cthulhu, AutoTonic, Arpology, Kirnu Cream, Ana 2, and HY Seq, that are already somewhat complex, and each have strong benefits. Nora is one that I did not purchase, because it looks interesting but seems to me to have drawbacks.
What is not clear is how the end goal meets the work flow, kind of from the end result to the simple data flow to the set up. Rather than from the setup (which differs in every DAW so can't be accurately shown without 20 vids), to the complex routing possibilities, and only barely showing an example tune that is mon-timbral and sounds totally quantized.
Is this use of Sidechained MIDI helpful to someone who can already play complex piano parts - or someone who can play medium level parts, or only basic parts, or is the plugin best used by driving it with pre-existing (whether quantized or unquantized) MIDI data? I've purchased a lot of plugins that were a little to complex or had basic or necessary features missing. This is why a bit more info would help.
