The MINIAK is a powerful performance and production synthesizer. The MINIAK empowers creative musicians with phrase and step sequencing, a built-in drum machine/rhythm sequencer, an arpeggiator, a 40-band vocoder, stereo effects, and a virtual analog synth engine developed in partnership with the world-class Alesis synth team. While the compact, portable synth shines on stage, the MINIAK is also at home in the production studio delivering 24-bit audio resolution.

Rounding out this complete instrument are high-resolution, 24-bit balanced 1/4" inputs and outputs. The MINIAK has a 37-key semi-weighted keyboard with velocity sensitivity for all-in-one performance. It can also be used as a sound source for MPCs, computer software, and keyboards via MIDI.

In a synth, oscillators generate raw sound. Their output is fed into the filters, whose output is fed into the amplifiers. As the signal moves along that path, you can manipulate the mix at several points and apply modulations, envelopes, and effects to create a custom palette of sounds.

The outputs of the oscillators, the noise generator, the ring modulator, and the external inputs are fed into a virtual mixing board called the pre-filter mix. From here, the signal hits the filters. For each source, you can specify its level and its balance: how much is sent to Filter 1 and how much is sent to Filter 2.

In the output stage, the MINIAK allows you to apply a drive effect and add some compression, distortion, or other amplification effects. The MINIAK allows you to set up twelve modulation routes. Each of these is a virtual connection between some physical or internally generated source and some program parameter. Basically, a mod route tells the synth to automatically grab a knob and tweak it while a note is playing. Although there are quite a few sources that you can use for your mods, the most common ones involve the LFOs and the envelopes.

The MINIAK has extensive sequencing and arpeggiation performance capabilities. Arpeggios and sequences both respond to a key-press by playing a series of notes over a programmed rhythmic pattern. An arpeggio loops over whatever notes you are holding down on the keyboard. If you hold down a chord, the MINIAK will generate a melody by playing each note of your chord individually. A sequence has a melody line built in so you can hold down a single key and the MINIAK will play back that melody relative to that key. Pressing another key will transpose the sequence.

The MINIAK has a full complement of stereo effects including Chorus, Feedback, Theta Flanger (Phaser + Flanger), Thru Zero Flanger, Super Phaser, Notch Frequency, String Phaser, 40-Band Vocoder, Analysis Gain, Sibilance Boost, Band Shift, Synthesis Input, Analysis Signal In, Analysis Mix, six types of Delay, and three types of Reverbs.

I see many Ableton Live users creating Vocoder-type voices through a timbre coming from some virtual synth like Serum, Diva, Sylenth1, you name it. That is, the Vocoder modulation doesn't come directly from the "Vocoder" instrument, but rather from the selected timbre in a virtual synth.

Sure, Logic has a vocoder in a few forms, and you can do this using the synth instrument version (EVOC 20 Vocoder Synth), and feeding the modulator (your voice) in via the sidechain (called the "Analysis Input" in that instrument).

Ok, that works but it doesn't address the detail of me wanting to use synthesis with a virtual instrument in the mix. I don't want to use just a Vocoder plugin; instead, I want a Vocoder plugin that allows the use of a synth like Serum to then do the modulation.

I am quite possibly wrong here, because I know that des99 is very often right, but I think that there is some misunderstanding going on here, and that it is in fact not possible to do what tiagodb asks for using the EVOC. Please correct me if I am wrong!

Now, I think that what tiagodb asks for is to be able to use one audio source (e.g. a voice) as the analysis signal, but another external sound source (e.g. Serum) as the synthesis signal. Is this a correct, @tiagodb?

True, but the sounds in the video can easily be generated with the EVOC20 PS.
Other tools in Logic can also do this, but using automatic pitch tracking - rather than keyboard input to define the pitch of the synth signal.
The EVOC 20 PS actully has 2 synth engines....FM and Dual mode - the latter can use any of 50 single cycle waveforms for each oscillator.
In FM mode, typical carrier / modulator pairing of sine waves.
There's also a noise source that is available for "unvoiced" signals (fricatives, a.s.o.).

The way that Ableton approaches things - basically separates the Analysis engine into it's own plug-in....and allows MIDI note input from a clip to control pitch. The output is sent to whatever synth engine you want to use.
While there is flexibility to this, I don't believe the Ableton vocoder can accept live MIDI input (perhaps someone can clarify?)

The Live vocoder is probably most equivalent to the EVOC20 TO plug-in....although the Logic plug offers internal scales/individual notes can be removed/added/tracked.

Bottom line...talking/singing robots, Darth Vader/Mickey mouse, or trashing drum loops, etc....definitely possible/easy to do in both apps.

2. On e.g. Track 2, place the audio material you wish to use as analysis signal. (You could also use live material, in which case you should choose the corresponding input as the side-chain in EVOC 20 TO, see below).

As for the @oscwilde, indeed the EVOC can generate sounds like in the video, but considering the plethora of presets from Serum/Diva/any other synth, my possibilities for creating a unique Vocoder sound increase dramatically.

Korg KingKorg Neo is a virtual analog synthesizer designed for today's musician, featuring a classic analog-like synth layout with swift, intuitive editing. With its XMT sound engine, 37 full-size keys, a dynamic vocoder and a suite of user-friendly features, KingKorg Neo is a comprehensive tool for artists who aspire to explore new realms of sound and push the boundaries of musical creativity.

KingKorg Neo features Korg's XMT virtual analog sound engine. XMT stands for eXpandedKEY Modelling Technology and was created to offer an expansive array of sounds while ensuring simplicity in operation via its preset oscillator algorithms. These carefully designed combinations of different oscillator types and quantities let you quickly shape rich, stage-ready tones with ease. KingKorg Neo comes loaded with a wide range of oscillator algorithms, from classic sawtooth and square waves to more intricate noise patterns typical of analog synthesizers and extending to PCM/DWGS.

KingKorg Neo is equipped with a diverse range of filter models, each adding a distinct flavor to your sound creations. Essential analog filter types sit alongside painstakingly modeled iconic filters from synths of the 70s, polyphonic synths from the vibrant new wave era of the 80s and even the legendary filters from Korg's own MS-20 analog synth. The filter models even self-oscillate when you dial up the resonance, a hallmark of classic analog synthesis. This capability opens up a world of sonic possibilities from creating ethereal textures to crafting powerful, resonant tones.

KingKorg Neo comes equipped with an XLR input on its front panel and includes a rugged, high-quality microphone for use with its powerful vocoder. At its core is a sophisticated 16-band filter; by shifting the filter frequency with the formant shift function and finely adjusting the level and pan of each band, you open the doors to an array of unique and original sounds. But there's more! Timbre B can be used as a modulator, providing an alternative to the traditional microphone input and allowing the vocoder effect to be seamlessly blended with the synth sound. Moreover, each of the three oscillators, A and B timbres, can be individually selected as a source for the microphone input, letting you synthesize a rich mix of voice and instrument.
