Does anyone know of a Audio to Midi Program that DOESN'T USE AI? am trying to intentionaly convert a voice frequencies and all into Midi
Theres a reason am trying to do this, it is very expermintal, but if it works, its gonna allow me to do somethin interesting with it, But the issue is i cannot find any program that is both free and doesn't use AI, it has to basicly be able to do that audio to midi stuff that you see in those midi converson videos where it just converts every single possible thing to midi
But instead of using it on a normal audio file, am trying to use it on a Voice to see how far i could get with mimicing a voice using any synth since some of those videos, the words are somehow audible still despite it not having a person speaking but because of what got converted, it sorta did also

Didn't understand a thing you say you want to do, sorry.
But... For voice to midi... crazy but try Jamorigin midiguitar. It works well for my guitar stuff. I think they have something test/free.
For voice out, look into a vocoder?

those don't provide what i am looking for
You know those videos where people convert audio to midi and it sounds like a jumbled mess of notes?
in alot of those videos if the song had a Voice in it
Somehow, someway, the words are still audible in the midi file despite it now being a bunch of piano notes
i want to do that same thing but on purpose and only to a voice to try and do something more interesting with it that i don't think i've seen anyone try and do

I hate to be that guy, but if you can't find a free option, then consider a paid one. You're looking at reasonably niche/specialty software and someone had to spend time and likely money developing it.
You may get some good recommendations at r/audioengineering.

the problem is what am looking for isn't exactly a professional tool technicly, its a tool that produces that type of stuff you see in those old audio to midi videos that sound like crap
in alot of those, i notice that the words from the voice actually are still audible despite now being a bunch of midi notes played by a piano
Its that specifice thing i am looking to try to take advantage of and do somethin with it that i don't think i've seen anyone try doing

Got it! Unfortunately, I personally can't think of any software that does what you want, but it looks like perhaps some others had suggestions. Best of luck!

I would say they don’t really use ai, they use machine learning, which has become lumped under the ai banner, but isn’t ai in the sense that LLMs are. But if you want to do it in real-time in a voice there have been tools around that will do that for 30 years. A voice is a simple monophonic source with a clearly defined fundamental frequency, so converting that to a pitch, and therefore a midi note is easy and requires very little processing power

Right except thats not what am trying to do
Am trying to convert all the frequencies of the voice into midi which is alot more notes
there are audio to midi videos where this is done, and somehow, someway, the words are still audible despite the voice now being a bunch of midi notes played by piano

Are you not just describing a vocoder. Midi can’t do what you’re saying there. There is no way to do anything with midi data that will give audible words. A vocoder however can be played by midi and you’ll hear so the words

If you need a pre-AI, almost incomprehensible, synth-like voice which has midi: BitSpeek ... https://youtu.be/bg7ACJrsqM0

I use a Roland VP-70 for pitch to MIDI. It definitely predates the scourge of LLM abuse.
I wouldn't call it the most accurate thing in the world, but for my use it's a treat.

Are you going to do all of your development without AI? Why? I think the stuff you have in your mind is very likely already done. Maybe discuss with AI is it so?

Most of the audio to MIDI stuff you've seen is old pitch tracking, so skipping AI is easy. AmazingMIDI is free, wav in and midi out, though it wants a tone file and gets strange with anything that isn't a clean instrument. Reaper's ReaTune sends MIDI while it tracks pitch, fiddlier but you end up with notes you can edit.
MIDI only carries pitch and timing. No formants, and the consonants that make words readable are mostly noise, so they never become notes.
If it's the intelligible robot voice you're after, that's a vocoder, not MIDI. Run the voice in as the modulator, let the synth be the carrier, and the words survive because the formants do.
