“Explore new sound spaces with VirSyn TERA that go beyond the emulation of synthesizer legends. Use the power of analog and digital synthesis combined with new physical models and new user interface elements to navigate through 8- dimensional sound spaces exceeding the limits of traditional sound morphing. The well-designed algorithms and the economical modular structure provides you with a comparatively high voice yield. Wireless patching of modules combined with an intelligent modulation matrix simplifies the development of new synthesizers from scratch. Up to 16 modular Synthesizers can be used simultaneously, all having the same user interface helping you operate this multi- modular system without losing track. Distortion, echo/delay and chorus/flanger/phaser effects for every modular synthesizer help boosts the sound into outer space. VirSyn TERA gives your production an individual character with its unique fat sound. Precise timing even with an external sequencer lets you feel the rhythm. Produce complete productions with VirSyn TERA as a stand-alone tool. Inspire yourself from the newly-designed 64 step- sequencer, expanding the concept of the classic analog sequencer with variable rhythmic structures and chord sequences. Or use the sequencer for real-time transposition of keys to play never-before heard arpeggios. Arrange up to 256 sequences in the song editor to complete the composition. And the integrated mixing console, together with a room simulator and a global chorus effect, helps you in the final production step.

Highlights of Version 3

Multi sampling

Each of the three main oscillators can use now samples instead of the built-in waveforms. The samples are organized in up to 16 key zones and 2 morph zones, making for a total of up to 32 sample files for each oscillator. Due to it’s high quality re-sampling algorithm, you can use a single sample for the whole tonal range!

Terrain filter

This new module allows for real-time morphing between two 16 pole filters selectable from a set of predefined vocal filters.


In addition to the high-level arpeggio functions of the built in sequencer, TERA 3 now offers a simple standard arpeggiator for each part.

Stereo routing

The amplifier module now has two additional stereo inputs allowing for stereo effects inside the synthesis patch. The spectrum oscillator has a new stereo output for stereophonic wavetable synthesis.


The four multi-segment envelopes in TERA can now be used in a new “free” mode where each envelope can be used independently. These envelopes can be saved and loaded from special envelope presets.
The standard envelope generators have also gotten a new Attack/Decay only mode.

Spectrum oscillator

The Spectrum oscillator has many new functions:

– uncorrelated stereo output
– spectrum presets
– separate spectrum parameters for two sets of oscillators

In addition to the additive sine synthesis used in TERA 2 as a basis for the wavetable generation process, the following methods can also be used:

– wavelet synthesis
– walsh function synthesis
– operator synthesis

Voltage controlled amplifier (VCA)

This new module works just like a ring modulator, except here one input is used to modulate the amplitude of the other input.

New module inputs

The outputs of the envelopes and the LFO’s can now be used as inputs for the signal processing modules of TERA. previously, these outputs could only be used in the modulation matrix.

New Modulation sources
Two modulation sources have been added:

Key alternate: can be used to get a different sound on every other note (IE: like bow up/down in natural string instruments )

Key random: creates a random control signal on every note.

Modulation matrix

The modulation matrix has been given a copy/paste function for transferring modulations between presets. Modulated parameters are indicated in the user interface through a color change of the parameter knobs.

8D control

The unique 8D morph control of TERA is now also usable for the six special synthesis pages introduced in TERA 2. The controller settings can be copied and pasted between presets and each dimension can be labelled individually.

“Fly over” tool tip help system

You can get more information on a particular parameter by moving the mouse over it, revealing a small window with detailed parameter info.

New sounds

The new TERA sound banks contain 256 presets, including some from the well-known sound designer Howard Scarr.
For the new sample module a set of about 35MB of multi-samples is included.
In addition to the traditional bank structure all presets are now available in a hierarchical folder structure for easy sound categorization and searching.
