TASCAM products were used for the live streaming of the New Year Festival Concert 2021, which was held at The Symphony Hall Osaka on January 3, 2021.

The audio was split from the PA equipment at the venue, and mixed for the stream by the Model 12 mixer, and fed through the LA-40MKII line converter (*) to a Roland switcher. The video from three different cameras was then encoded by the VS-R264 and sent to a YouTube live stream. (*) The LA-40MKII is now discontinued. The successor is the LA-40MKIII.
