“FlexTally”, a General-Purpose Wireless Tally Lamp System, is Now Compatible with The Software Switcher “vMix”
Wider use is now possible with both hardware and software switchers

Cerevo Inc., an Internet connected consumer electronics manufacturer based in Tokyo, Japan, has released new firmware on July 24th for the general-purpose wireless tally lamp system “FlexTally” which will now be compatible with the software video switcher “vMix”, made by StudioCoast Pty Ltd. (Headquarters: Australia)


FlexTally is a tally lamp system that is shipped as one station unit (base unit) for connecting to a video switcher and four lamp units (portable units) for connecting to cameras. When multiple cameras are used to shoot recording of programs or live streaming, the FlexTally lamp automatically turns on whenever a switching command is detected from the switcher so the people on air can easily identify which camera is being used.

Since its launch, FlexTally has been globally popular among professionals and private users alike because of the ease and convenience to adopt and operate it. At the world’s largest show for media, entertainment and broadcast technology “NAB Show 2019” held in April 2019, we demonstrated switching that was compatible with “vMix”, and now this has been officially released. Using the latest firmware update, all FlexTally units will be compatible with “vMix”, enabling more options to achieve a professional video switching environment.


Currently, there are 15 types of switchers that have been checked for operability and compatibility with FlexTally, including Cerevo’s own switcher with live streaming functions, LiveWedge. FlexTally is compatible with other brands switchers*1 such as Blackmagic Design’s ATEM series, NewTek’s TriCaster series, as well as other switchers that support GPIO-capable connections. In becoming compatible with “vMix”, a broader use with either hardware or software switchers is now possible.

Using FlexTally with vMix
To use vMix, please update the firmware on your station unit. In addition, if you are using in Ethernet mode, please install version 1.1.0 of the FlexTally Utility application. If you do not use vMix, there is no need to install the firmware update or the newest PC application. For details on usage, please check the online manual.
