HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (0.3 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Sounds great, but…

Sounds great but doesn’t work with my ewi. Can you guys make this work as well as PIPA does? I actually purchased this synth because Pipa was so fantastic. Please fix

★★★★★Dec 12, 2021
amazing developer

i love these synths and only use these

★★★★★Dec 8, 2020
meh

so i wasn’t looking for this. it was basically a waste of my $7. but it’s still good to annoy my friends with high pitched drill-like noises!

★★★★★Dec 6, 2020
The girl with the nonfunctional tattoo

Does not work at all in GarageBand...in any configuration whatsoever. Thanks a lot, Sweden. I am unemployed so $7 wasted is a lot of money for me. So disappointing.

Does what it does

This is a vocal synth. It produces a synthesized voice. There are a few variables to control but this is not subtractive, modular, granular or FM synthesis. It’s a voice w/ some parameters to adjust but it’s still the same voice. There’s not a way to control the vowels that the voice sings. In fact, it makes a sound that is like all vowels combined or perhaps, absent of any vowel sounds at all. It’s like a voice singing trying to sing “aahhhhhh” but it sounds more like “uyghhhhhhh”. You can get a lot of weird sounds from it. It definitely sounds like a voice. It’s klevgrand so it’s good. I think it’s great. I read the reviews first. I got exactly what I was expecting and hope this helps someone else to expect exactly what they’re getting.

Prima!

Ich kann nun das hohe C von Jussi Björling simulieren :-). Auch die anderen Klänge sind interessant und gefallen mir gut ...- eine liebevoll gestaltete App.

- Updated keyboard - Midi support - Export/import presets

Released Sep 23, 2016. Current version shipped Nov 22, 2021.

Store description

This synthesizer emulates male voice vowels in a unique way. Thanks to a set of powerful parameters you can make Jussi sing anything from soft and airy choir-like vowels to hard and angry shouting. Formants are controlled by playing with different velocity, which makes it fun and easy to play using a MIDI keyboard. Features: • AUv3, works with AUv3 compatible hosts like Garageband, Cubasis, AUM etc. • ADSR with ”Turn-in” and ”Turn-out” option (Turn-in and Turn-out affects the pitch and maps it to attack and release) • Voice character XY pad (Intensity and Narrowness) • Legato mode (glides between notes and velocity levels) • Legato Hold mode (polyphonic legato when using a sustain controller, consult the documentation for more info) • Throat emulation XY pad (Grain and Tonality) • Built-in reverb iPhone 6 or later is recommended. iPad 4 or later is recommended.
