Heavyocity Mosaic Bass Review

The latest Kontakt Library from Heavyocity is Mosaic Bass. It includes 3 Gb of synth bass sampled content with close to 200 snapshots and over 1000 individual samples. The presets are broken into 2 categories, aggressive and mellow. And each of those is broken up into 3 sub-categories, Playables, Rhythms, and Pads.

Mosaic Bass was no doubt designed for scoring (it’s Heavyocity after all.) It’s great for ambient type drones as well as pulsating tension cues for the Investigative/Lab scene type genre. Despite the name, you can get some cool sounds that aren’t Bass sounding by playing in a higher register. I’ve really taken a liking to if for chill-hop and mellow type electronic music.

Mosaic Bass Mixer Section

The first thing you’ll notice is the giant circle in the middle of the screen. This is called the Macro knob and can be modulated to control the 6 sliders you see to the left and right. This can create constant motion, making your typical pads and bass sound more exciting. Each setting controls 3 channels as each preset consists of 3 samples/channels. You can turn each of the 6 sliders on or off as well as limit the range.

Through Mosaic Bass, you can control the motion/modulation by clicking on the up/down arrows next to a control, and dragging up or down. This will set the upper and lower amount for the control. Anywhere you see the link icon (looks like two squares) this will let you link all 3 channels so they are controlled together.

Control Section

At any point you can click on the name of each slider to jump to the control tab. The control tab will adjust to display the settings for each of the 6 slider categories. The envelope section has 3 channels and boasts your typical ADSR envelope. Additionally, there’s a SYNC knob to sync the attack with the host tempo. START adjust the start offset, RND will randomize the start offset and WIDTH sets the stereo width. EQ and Filter are about what you’d expect. Drive offers 3 types of Saturation, Tube/Tape1/Tape2 as well as 3 types of Distortion, Stomp/Amp/Lo-Fi, again this is for all 3 channels. There’s also a Gate for gating effects with Heavyocity’s typical sequencer interface and Space for reverb and delay effects.

Macro Modulation

The star of the show is the Macro Modulation tab. While you can turn the Macro Knob manually, this page lets you modulate it in an automated fashion. You can set the Rate and Steps as well as the Type (Retrig/Legato/Free Run/One Shot) and Shape, which has Heavyocity’s typical settings (Triangle, Comb, Ramp Up/Ramp Dn/ Random.) This is what makes the library so cool. At the bottom of the page, each channel is represented with a Mute/Solo and Volume knob. You can also select the name of sample and it’ll pop open the Options tab.

Mosaic Bass Macro Seq Section


The options pages lets you browse and pick samples for each channel. You can also set the key mapping range for each. Velocity and pitch bend ranges can be set per channel as well.

Options Section


There’s an arpeggiator for each channel. You can set each to a different rate with a different number of steps. Like the Macro Sequencer, you can pick (Retrig/Legato/Free Run/One Shot) for the Types. You can also apply a gate and swing to the arp.

Master FX

Heavyocity included it’s Punish knob in Mosaic Bass. Turn it to crank the saturation and compression. The filter cutoff controls the frequency to filter at and the Res sets the resonant peak of the cutoff. Type allows you to select from a handful of typical shapes. There’s also master delay, reverb and EQ.

To show how this can be used for not just Bass, but also Lead and Pads, here’s an example with all 3.

Potential Jazztronica or Chillhop song

Here’s a pulsing mellow lead.

Final Thoughts

Mosaic Bass is pretty useful for certain genres. While I haven’t found anything in there that’s great for Hip Hop or EDM, it is definitely useful for film and TV scoring, as well as any of the Chillout sub-grenres. The nice thing is that it’s not crazy expensive, so adding it as an extra library won’t break the bank. If you are just starting out, but don’t have a tool to create these type of sounds, this would be a really good option.
