Overview

The Mark79 is based on a 1979 Mark II 73 Keys Electric Piano from 1979.
The first Mark II were identical to the Mark I's in terms of sound generation part, meaning that the hammers, hammer tips, the tines and the amplification were the same as the late Mark I models.
That being said, there is a noticeable difference when compared to the early Mark I models, the tines were not made of the same exact material and ended up producing a more even sound with a bit lett highs and more controlled bass. the attack and sustain characteristics changed a little as well.
All this added to the hammer tips changes makes the MarkII sound different from an early Mark I and deliver the tones of the well known Chick Corea's "Return to forever" sound.

Features

Authentic tine sound

Authentic tine sound
We recorded the Mark79 from both the direct output using a state of the art DI (Universal Audio Solo 610) and also using a pair of microphones right above the keys next to where the head of a player would be.
With our precise resonance model, our detailed staccato and release adjustments and the meticulous velocity layer transitions, the Mark79 is truly the most detailed and accurate recreation of the famous tines electric piano sound.

More about this

In this panel, you can change most of the aspects of the library to make it sound just like you want.
You can adjust:
  • Acoustic / Electric volume controls.
  • EQ, Bass and Treble: a parametric EQ with the two knobs available on the real EP.
  • Vibrato: the stereo pan of electric pianos is really a part of the sound, here you can control the amount and speed of it. We also addedthe possibility of a volume tremolo as players ofter use the volume knob to create that effect.
  • Distortion: the MarkII has often be played with a distortion so we decided to add it.
  • Reverb: We used an IR of a spring reverb to mimic the most used reverb on this kind of instrument.
  • Cabinet: You can turn on or off the amp simulation.
  • The release Volume: the sound produced when you release a key if a note was going on.
  • The Pedal Noise: the sound produced when you press or release the pedal, it adds a lot to the realism.

Amp simulation

Amp simulation

We have been looking for the most widely used amps with Electric Pianos and we created advanced impulse responses of them. Here is a list of the Amps that you can choose from:

  • Rhodes Amp mono ans stereo and at different distances,
  • Twin Reverb,
  • Twin Reverb wide stereo mics,
  • Bassman,
  • SilverFace,
  • Mesa,
  • Gibson,
  • Fender 212

You can of course turn it off and use you preferred amp simulation software.

Built in FX selection

Built in FX selection

The Stereo pan is the signature sound of the Electric pianos, you can control its depth and rate and even change it to a volume tremolo.

We also included a few FX that you can control from the front interface.

  • A two band EQ with Bass and Treble controls
  • A tube distortion
  • A Spring reverb
  • An amp simulation wirh different cabinets

MIDI controls

MIDI controls
As always with our libraries, you have a complete control over the response of the library. The Velocity Sensitivity changes the volume curve of the library.
The Dynamics will set the minimum volume for velocity 1 and give you access to all the dynamics that you want.
The velocity curve remaps midi input and will give it a concave or convex shape thus changing some sort of a "MIDI sensitivity".

Sample player

VSTVST3AUAAXStandalone

Mark79 plays in UVI Player (formerly UVI Workstation), UVI's free sample player. We provide it with every library you buy, so you don't need an expensive sampler to use our products. It works on Mac (macOS 10.14 or later, Intel or Apple silicon) and Windows (10 or later), standalone or as a plug-in (VST / VST3 / AU / AAX), in 64-bit only. More about it here.

Copy protection

We use the iLok system to protect our products and you can choose to register your license to your computer or to an iLok dongle. If you decide to use an iLok dongle, both V1 and V2 are compatible with our products. You can activate your license on up to 3 computers or iLok dongles at the same time and you can deactivate one and activate another as many times as you want.

Registration

Once your order is complete, you will be provided with a serial number. You will then be able to register it to your iLok account from our website on this page (you need to be logged in to access this page). The whole process is described in the FAQ (instructions + screencast).
