The idea for my own VST sequencer is dated back to late 2016 (for example my track Night Attack). I was trying to find VST sequencer which would allow me to experiment with random steps order. At the end I decided to write VST of my own. This also explains delay of the album; it took several months to get the VST working. It's used in every track through the whole album and I believe this gives it a bit unusual sound.
Chrysalid Arp is closely based on the sequencer, using the same algorithms to make random arpeggios. You can hear what these two VSTs can do on the bandcamp.
