Question Does anyone here have experience with "weird noises" when using Kasane Teto?

[UltimaKirb]

I'm using Kasane Teto for my school's science fair, and my subject is manipulating sounds to sound like other instruments. I was wondering if anyone here knows methods that cause Teto to make weird noises, such as sounding like a drum, a brass instrument, etc.

If you guys have any info on this, thank you so much in advance!

The good news is people synthesize all of those all the time, with regular synthesizers and drum machines. You just need to be a little creative with the quirks of a vocal synth. And a capella music is already a thing, so that works too.

A kick drum is a low sine tone (55Hz for a classic 909 drum) that very rapidly dives down in pitch. So, try making a note with a plosive phoneme, like "Ba" in a low octave, and draw a pitch curve to make it quickly move down an octave or two.

Synthetic cymbals can be made with white noise modulated by a synth's amp envelope. So...have Teto say "tiss," maybe with growl to add some more buzz to the sss part. (I don't own SynthV, so I assume it has growl and an equivalent to DYN in Vocaloid.) Then you want a volume curve to make the plosive "t" sound loud, and then gradually fall off over the rest of the sound.

Synth brass is usually made with two oscillators playing sawtooth waves, with one detuned by a bit, and some sculpting with the amp envelope and filter. I can't think of anything more specific/directly applicable to a vocal synth, but I'm sure it could be done. It just might need some resampling and playing with external effects.

These are untested, but they're what I'd attempt from my knowledge of synthesis.

*edit* Didn't realise this was in the UTAU section! Luckily most of these still hold up.

Some fun things you can try:

1. Set any parameters to extreme values. They're generally not intended to be used at 100%, so these create strange effects.
2. Add large, sudden, off-key changes in pitch. You'll get lots of odd gasps, yells, and generally surreal microtonal wobbling. For example, a dense group of dramatic pitch bends creates a raspy, gargling noise.
3. Try short, unnatural notes, and push the voicebank as far out of its normal range as is audible.
4. If you have the software, use the audio-to-midi function in Synthesizer V and convert a recording that isn't of someone singing. This will allow you to see what different sounds look like in vocal synth software, and get some generally weird looking phonetics and pitch bends to take inspiration from. An alternative is Spotify's free Basic Pitch midi convertor (although this obviously only gives you the notes and no phonetics).

If you're willing to use her English UTAU bank, she has oto entries for consonants by themselves, which might be fun to play with as instruments.
