Virsyn TERA 3 is a modular software synthesizer based on many different synthesis technologies including the revolutionary Spectrum synthesis.

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.

Arpeggiator
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.

Envelopes
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 •pectrum 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.

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.
