Advanced Librarian

We have added some really cool features and quality-of-life improvements to the already amazing librarian in NEXUS4.

Featuring three columns for easy navigation.

Counters for folders, categories, and presets to give you an overview at a glance.

Color-coded tags, bookmarks, favorites, and a dedicated location for user presets.

History function: Easily go back a step (or two, or three, or more) - and forth again if and when needed.

Quickly find what you're looking for with instant sound preview, search-while-you-type, filter by category and tags, and so much more.

Arpeggiator Deluxe

Access all sixteen layer arpeggiators, in addition to the main arpeggiator.

Never lose track of what's happening with the fully interactive, zoomed-out overview at the top.

When zoomed in, the new "follow" option always scrolls with the playback.

Extend the pattern length up to 256 steps and play the most complex patterns you can come up with.

Sequencer mode: Create the most complex patterns with multiple notes per step and set the velocity individually. Zoom in on the x-axis or the y-axis to make fine adjustments or zoom out to have an overview of the full pattern.

Editing has never been so comfortable. This is the best Arpeggiator you can find on the market!


Full visualization of the signal-flow for real-time feedback:

You see what you hear and you hear what you see.

Five insert effects, four equalizers, filter, reverb, delay, and impulse. Color-coded for navigating incredibly fast.

Now featuring an incredible glitch effect and the brand-new OTT compressor.

Effects can be rearranged by drag'n'drop and the entire FX chain can be saved and loaded.

All on one page. No clicking back and forth countless times to get to the desired result.


Clean and comprehensible visualization of the signal-flow per layer. Easily pinpoint what affects the sounds.

Enable or disable entire layers with one click or play around with individual effects and oscillators.

Easily adjust the level, panning, and tuning of the oscillators.

This enables you to split complex SQ sequences into their components and single out individual sounds (just the bass, for instance) to easily create your own melodies.

Convenient and easy to use.

Improved Cloud-Sync Feature

Automatically store your favorites, bookmarks, user presets, and settings in the cloud.

Getting back your content when installing NEXUS4 on a new computer has never been easier.
