Solid GUI + Presets

SKU: PM-0008 Categories: , Tag:


Solid Single Rack.

"monolith" is a completely redesigned GUI for U-he Ace, with many extra features added.

  • Single pane. No tabs at all
  • Modern GUI Size : 1320px x 820px
  • NI Massive style modulation
  • Colors tell you mod sources clearly
  • Ghost mode - Hide all cables
  • Graphical feedbacks for FX
  • Fullscreen MMap editor
  • Bundled with 48 bonus presets

Compatible with ACE v1.4.1 (with new preset browser).

What You See is What You Plug.

The whole modulation system is massively improved! Colors, icons and texts tells you a lot. Now you don't need to follow each cables with your eyes just to know where it's routed.

  • The "Massive Modular System" : Rings around knobs show mod depth.
  • Ring color changes according to its mod source!
  • Mod Sources are shown as an icon + short text.

In the original skin, the labels for default mod sources remain shown even after it's overwritten by other sources, which makes you confused all the time. It never happens in monolith skin.

What monolith aims is a hybrid modular synth : Analog vibes with digital functionality!

Ghosts are with You.

monolith incorporates the "Ghost Mode" feature, just like Tokyo Ghost Skin for Bazille.

  • Click the topbar icon and all cables are hidden.
  • You can still change mod sources by clicking dropdown menu icon!
  • Mod Src boxes are remain visible, so you can still see how they're routed.

Cables will no longer disturb you after patching are finished.

This means, extremely, you can use ACE completely as a cableless synth if you want!

Source of Inspiration.

Chorus & Delay have visual feedbacks, which display the combined results of a couple of parameters.

  • Delay : Sync + Feedback + Spread
  • Chorus : Rate + Depth

It especially helps when you load through many presets.

Seek for the Light?

In v1.1 update, The light version is added. Choose the color you like!

The monolith Soundset


The monolith theme comes with a bonus preset library. Though it's not a big package, they're designed in detail and have nice touch of analog modular synthesis.

  • 19 Bassses
  • 12 Leads
  • 15 Pads
  • 8 Plucks
  • 10 Keys
  • 64 Presets in total.

Every preset is Mod Wheel ready and fully tagged!

Listen to the sounds

We are so much proud of its sound quality that the demos all are a solo demonstration of a single preset in turn. No external effects are inserted (except for keys sounds). In some tracks mod wheel is used to show how the sound morphs.

(If the player won't start, please try selecting another track or reload page.)
