Recently I wanted to make a trance track but I lack vocals, and I'm looking for MIDI to voice conversion

I constantly see AceStudio marketing itself (398$) on Facebook but I also notice ads of Dreamtonics Synthesizer V Studio Pro 2.0, which outdated version is available at sister site under the name of "Dreamtonics Synthesizer V Studio Pro v1.9.0 + Voicebanks Win", which I'm downloading now

Once I'm done I'm gonna mix the potential results with Applio's RVCv2 models mixer to have unique voices

Spoiler

If you wonder why I can't just record my voice and then inference it with other model the reason is simple — I am a male and female voices are fundamentally different and no amount of formant shifting can change it. If you ever watched these AI videos with women singing men's vocals you know what I mean

Are there any other, "nerdy" alternatives that may have obviously harder workflow but are FREE?

Spoiler

i know about vocaloid/utau but all of them sound too robotic and dont have too much english voicebanks
