While the PS3 and Xbox 360 had a wealth of games available, one genre rose and seemingly died when next-gen came around: the music game genre, or more specifically Guitar Hero and Rock Band games. The return of the genre doesn’t seem to have stuck however, as Mad Catz, Rock Band 4’s instrument manufacturer, is reporting a $11.6 million loss in 2016.

The estimate comes curtsey of the company’s year-end earnings report. Terminating their contract with developer Harmonix, Mad Catz states that the company needs to sell a “remaining $8.3 million of Rock Band 4 inventory” in the space of 120 days.

Despite the financial blow, Mad Catz isn’t worried after a recent boost in sales of audio and fightstick products for Xbox One and PlayStation 4. The loss of $11.6 million in 2016, however, is a sizable drop from their 2015 report which showed that the Mad Catz had a $4.7 million profit.
