Please read these instructions carefully to save our Discord Server from being overloaded with questions regarding the setup of the emulator.
Performance Test Download Links
If you are curious about how well your system will perform while running the emulator, please download and run the test program from one of the following links below to see if your CPU is capable of handling it. The Firmware for the Virus TI will need to be placed in the root of this folder for it to work (we can not provide Firmware files, so you will need to make your own arrangements)
Win / Mac / Linux x64 / Linux aarch64
Once you have downloaded the test program run the virusTestConsole.exe file by itself to execute the test running the Factory Demosong.
As the Virus TI runs each DSP at 133 MHz a combined result for both DSPs of 266 MIPs or more is needed to run it.
The Virus TI Snow uses 1 DSP at 163 MHz, so 163 MIPs is needed to run it in Snow mode (currently not a configurable option for the Performance Test utility).

OsTIrus 1.3.8 (2024.03.11)
DSP:
- [Imp] Performance improvements
- [Imp] Reduce host memory consumption
Framework:
- [Imp] Patch Manager added. The patch manager replaced the old preset browser and provides a modern
user experience to manage presets. Introduction:
Patch Manager Introduction
- [Imp] The DSP can now be underclocked/overclocked via context menu between 50% and 200%. This is
an advanced setting that needs to be confirmed before activation
More info:
Advanced Setting: DSP overclocking/underclocking
- [Fix] Parameter value change by double-click on knob to reset it was not sent to host for automation
- [Fix] Linked parameters confused Bitwig / Ableton and other hosts
- [Fix] Long plugin loading times in some hosts due to excessive initial parameter automation updates
- [Fix] Part context menu and global context menu opened at the same time on right click
Osirus/OsTIrus:
- [Imp] Parameter regions can now be locked/unlocked via a context menu. Locked parameters do not change
when a preset is loaded. This is useful for example if you want to keep an Arp pattern
while searching for a preset, etc.
- [Imp] Added output gain adjustment to context menu (already present in Vavra before)
- [Imp] The Midi Receive Channel of a part in Multi Mode can now be adjusted by right clicking on the
part select button
- [Imp] Patches can now be copied to other parts via drag & drop
- [Imp] Support more file formats to load presets from. All supported formats now are:
.syx/.mid Virus A/B/C/TI/TI2 preset dumps
.fxb/.vstpreset Presets saved by DAW from Virus Powercore and Virus TI Control Software
.cpr Cubase Project Files
.mid Virus A/B/C OS Update files that include Factory Presets
- [Imp] Disabled poly pressure to control Page B parameters to prevent accidental patch changes
by keyboards that emit MPE messages
- [Fix] Virus A presets from a very old firmware failed to load
OsTIrus:
- [Imp] Removed demo restrictions (enabled save of plugin state, enabled preset export, removed demo banner)
- [Imp] Device samplerate of 48 Khz is now supported, previously only 44,1 KHz was used for the
Emulation. If 44,1 KHz or 48 Khz is used is automatically determined based on the
host samplerate.
- [Imp] The DSP code supports more samplerates than the hardware device was able to handle and
ranges from 32 Khz to 96 Khz. The samplerate can be overwritten in the advanced options
context menu. The chosen samplerate is preserved as part of the plugin state.
Note that higher samplerates may reduce the voice count if the DSP is not overclocked.
More Info:
OsTIrus / Virus TI with 96 KHz Sample Rate
- [Imp] Removed ROM banks that are empty anyway
