Just installed and poked around a bit. In a short time, I was able put to use in a sequence (FL Studio is my primary platform). With one track playing a melodic sequence and the Homegrown ARP track sent to the same synth via MIDI out, I had a nice "more complex" melody being generated. By simply toggling in the ARP on such controls as "latch", 'hold" and "polyphonic" ("muters" was the default selection in the patch I chose), I was able to very easily generate some very nice melodic variations.
Would lend itself nicely to live playing with controller buttons mapped to the ARP controls.
I may come back and rate it higher later. I gave it an "8" initially as I was able to get some fun results with not much effort. Downside is "lack of a manual or tutorial video" ... but the ARP VST is inexpensive. I may "up my rating:" later with more exploration. I only touched about 5% of it's features. This could potentially be a "10" in compositional variation value for this price range.
The demo version is fully featured, but times out after 30 minutes per session.... so anyone can try it out to see if it fits into your "melodic toolkit" before you buy.
