Bad title, I know. But I concocted this idea a while ago.
When I became a fan:
-It was early 2015, around February or March, and I was an active fan until around late 2016 and since then I'd flicker off-and-on until becoming a producer (even when I wasn't a fan, it was almost a personal TRADITION to listen to Miku in the car on long road trips though, and it kinda still is).
-The latest VOCALOID engine, I believe, was VOCALOID4, and it was still fairly new; only two databases had come out at the time, VY1 and Cyber Diva.
-Hatsune Miku was on her V3 and V3 English voicebanks; VOCALOID4 was still fairly new and most synths were still on their V3 (or V2...or V1)
-Luka V4X was about to come out
-The Kagamines were on their V2 and thus could not speak/sing in (supported) English yet; Miku, of course, did not yet speak Chinese
-There wasn't a huge amount of free vocal synths at the time; I think most stuck to UTAU. We have been blessed (or cursed) with many free/free-version vocal synths since.
-Leon, Lola and Miriam may have already been quote-unquote "dead"
-Project Mirai DX was coming soon (I got it not too long after its release date)
-The latest Project Diva game was F 2nd (I believe I eventually got all 3 of the "F-style" games; F, F2nd and X, I mean.)
-Vocaloid was still pretty much at the top of the VSynth food chain with UTAU following close behind. This was before SynthV became a sensation and CeVIO rose in popularity.
When I became a Vocaloid producer:
-I bought the Hatsune Miku V4X Bundle on June 6, 2021. (I also bought AVANNA on 8/17/21, Miku V3 English on 8/20/21, and SONiKA on...technically 8/18/22, it was pretty late at night).
-There were many more free options available for vocal synthesis, such as DeepVocal and Synthesizer V Studio Basic (the latter I predominantly used before I bought Miku and I still occasionally fiddle around with today)
-Hatsune Miku's latest vocal package was NT (her NT appends wouldn't come out til a little later though); when it comes to English and Chinese, her latest is still her V4. (I bought her V4 bundle both due to Miku V4X sounding less wonky than NT and due to the included English voicebank (also just more voicebanks in general due to having Soft and Solid). I kinda like NT's sound in a way but I'm glad I chose V4X in the end.)
-Vocaloid had decreased in popularity, with Synthesizer V and CeVIO AI quickly overtaking it. However, VOCALOID seems to currently maintain a steady "nostalgic popularity" especially with the continued popularity of vocals like the Cryptonloids and Flower.
-The latest Vocaloid engine was (and still is) VOCALOID5; however, you can get an "earlier" Vocaloid engine with Piapro Studio (V3 API; V3 Cryptonloids) or Piapro Studio for V4X (V4 API; "V4X" Cryptonloids) and some VSynth companies still sell their VOCALOID2 vocals which means you can get that editor as well. (Thankfully V2 vocals work in Piapro, since I have Sonika and English in V2 is hard!)
-Miku started collaborating with other franchises more frequently.
