Jussi - Vocal Synthesizer by Klevgränd

Klevgränd brings us another unique addition to our iOS arsenal with this beautiful looking vocal synth, Jussi! Although the app is intended to be used inside of an Audio Unit host, it will work in a limited capacity as a standalone app.

Jussi iTunes 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.


  • 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

Note: Jussi in stand-alone mode does not support IAA, Audiobus or MIDI. You can play it using the keys at the bottom, but that’s it. We recommend using Jussi with AUv3 compatible hosts.

iPhone 6 or later is recommended.
iPad 4 or later is recommended.

Buy Jussi - Vocal Synthesizer on iTunes: $4.99 (On Sale, Intro Price)

Here is the preview from Jakob Haq, where he covers the most important elements of the app; like how to pronounce it!

Howl: A Formant Synthesizer

Back in December, Howl was released as a unique formant synthesizer. Today the app gains new life with Audiobus! The app is now Universal as well, with the addition of iPad support!

Howl iTunes Description:

HOWL is a simple vocoder/synthesizer. It uses formants to simulate the human voice and a pitch-space keyboard to help you find interesting melodies.


  • Simple synthesizer (just a sawtooth wave nothing too complicated okay)
  • Simple vocoder (four parallel bandpass filters, a bit like the Klatt engine)
  • Audiobus support, so you can pipe your own audio through the vocoder and/or send the output to other software
  • Adjustable pitch-space keyboard
  • Cool FX (bitcrush, reverb, vibrato and tremolo)

HOWL is also open source (check out the code at https://github.com/dclelland/HOWL).

What's New in Version 2.0:

Everybody asked for Audiobus support, so HOWL now supports Audiobus! I've also rebuilt the UI so it scales up on an iPad. It looks gosh darned fantastic on that big touchscreen.

I've also added a few more features and effects, including a two-axis LFO to the vowel pad. 175% more knobs and dials!

Naturally Doug Woods has a demo for this one! Note that this demo is for version 1.0.
