Mosaic Leads By Heavyocity

Mosaic Leads By Heavyocity


KK-Access Review


Heavyocity are kicking off the new year with the sixth addition to their popular Mosaic product line, this time it’s the turn of Lead instruments to find their way into the now familiar Mosaic Kontakt engine.


Leading the Way…


Whether you are looking to create a memorable and catchy hook line, or want to show off your keyboard chops in a flashy instrumental section, we all make use of leads at some point in our compositional life, and in commercial music having a dedicated collection on hand can be both an inspiration and time saver when seeking something to fit the tone of a project.


This is where Heavyocity’s Mosaic Leads becomes a welcome new family member to the ever expanding series of mid range cinematic libraries.


Tech Spechs…


Mosaic Leads runs in Kontakt 6.6.1 either full version or the free Kontakt player equivalent, and has NKS support for use within Komplete Kontrol.


The library will occupy 2.5GB of your hard drive space, compressed in NCW format from the original 3.12GB of sample data.


There is 1 master Kontakt NKI file, which feeds the 102 further NKSN snapshots which Komplete Kontrol makes use of.


Download & Installation


Download of the library comes courtesy of the Heavyocity Portal, which is fairly accessible and is achievable without the need for sighted assistance. This is a case of pasting in your provided authorisation serial to register the product, and then choosing your install location, and letting the application do it’s thing.


The final step is to use the same registration serial to authorise Mosaic Leads within Native access in the usual way.

Loading up Komplete Kontrol within your DAW as a plugin and pressing browse, you will hear KK confirm the scanning status, and you are ready to go, without the need to run the standalone version of Komplete Kontrol.

As with previous libraries in the Mosaic series, Leads retains a basic level of tweak ability for blind users within the realms of it’s factory presets.


Mosaic Leads makes plentiful use of classic analog synth articulations, most notably the glide feature used within a number of the patches.


I was pleased to see that NKS controls to turn this on and off, as well as glide time control has been mapped to the Komplete Kontrol knobs.


Likewise the ability to switch from monophonic to polyphonic is a welcome addition that works well for a library of this type.


It would have been nice to have seen some cut-off and resonance NKS mapping to gain some control over the filter sweeps and modulation which I feel probably exists within the visual user interface, however this would ultimately lead to a further emerging wish list for ADSR and other desirable sound design parameters


NKS controls for reverb and delay are global, which in some instances can mean that despite delay being turned off, if one of the 3 other layers that make up a preset has it’s own FX already switched on, then we are unable to accessibly turn it on or off on an individual basis.


I did as usual in the course of the review cross reference the parameters that had been made available for automation by loading up the master NKI within Kontakt on it’s own and looking at the parameter list within my DAW (Reaper).


I did find an additional Macro control and filter range, as well as tuning for each of the channel layers, I am not sure why the tuning controls have been omitted from the NKS mapping template on this outing.


Taking the Lead…


Despite having some accessibility limitations , Mosaic Leads does go on to present us with a useful collection of well polished Lead preset sounds in the now imitable Heavyocity style, that fully compliment their other products.


There are plenty of striking analog synths to be found here, laced with aggressive dirt and atmosphere that can very capably punch through a busy mix, or just as easily stand up for themselves in isolation. When soaked in their own reverberant space, they readily demonstrate huge cinematic potential, perhaps conjuring imagery of a stark dystopian landscape.


Conversely there are plenty of similar opportunities to show off more temperate and ethereal timbres should your work call for some more subtle and dialled down textures.


Arp, Playable & Rhythmic…


The presets within Mosaic Leads are divided into three distinct sections, which refer to their playing format rather than genre, which is left to the users own discretion.


Arps as you would generally imagine refer to those patches which are tempo synced and follow the chord and note progressions that you choose to play.


Whilst this is certainly the case, remember that there are anything up to three layers of samples being played within any given preset, so it could be that channel 1 has gated short notes busily playing a more traditional arpeggio , while channels 2 & 3 perhaps has longer string or pad type samples or something more textural going on.


The presets are certainly not static in any sense of the word, as both the Arp and Rhythmic sections are sonically vibrant with movement, either evolving with modulation or stereo imaging fx that will maintain listener interest.


Some of these modulations can be accentuated using the mod wheel as a form of expression.

In terms of further articulations or switchable modes, I did not find the presence of any keyswitches for this library.


The Mosaic Leads Playable section takes any tempo synced DAW interventions out of the equation, and leaves you to knuckle down to your own keyboard talents with a collection of 45 presets.

<pre class="wp-block-syntaxhighlighter-code"><br />      Again there are good examples of the signature Heavyocity cinematic style going on here, with dark and moody patches such as 'Ambient Cloud Runner' readily offering up the apocalyptic vibe, with a long sustained held note seemingly disintegrating as it evolves over time.</pre>


The Glassy and metallic timbre of ‘Distant Past’ change things to a more melodic tone, whilst ‘Low & Slow Peaks’ take you into the realms of a Theremin on steroids!


The always carefully cu rated Rhythmic presets are again present, with 28 patches that provide a cross section of tonal and rhythmic variations in both straight and triplet time.


It would have been a nice option to be able to change the timings of these along with the Arps section to 1/4, 1/8, 1/16, 1/32 via an NKS control or keyswitch, but alas unfortunately we are kind of stuck with the default setting with no obvious accessible way for us to tweak this.


There are as always some great videos released by the Heavyocity team that show off the new library in all it’s glory (linked at the review footer), but if you do own other Heavyocity products you can be assured that these sounds will fit right in with existing material.




Mosaic Leads is sure to add fresh inspiration to any existing Heavyocity users sound palette, with these new score ready presets having been diligently crafted to take centre stage and compliment a wealth of music styles within a modern cinematic genre.


Mosaic Leads by Heavyocity can be purchased directly from their website, for a limited time, Heavyocity is offering Mosaic Leads for $99 (reg. $119). In addition, owners of other Mosaic Series instruments will receive an additional 20% off. Offers end January 27, 2022.
