by KeepForest Review

AizerX – Modern Designer Toolkit & AizerX – Trailer SFX Designer Toolkit is two new releases made available by KeepForest. These two different products and libraries that are aiming towards two different audiences. Both libraries are bought on their own or when possible as a bundle. You can use both libraries in combination if you want to manage your spend you need to look for your main projects and select the required library from KeepForest.

AizerX overview

AIZERX – TRAILER SFX DESIGNER TOOLKIT equipped the composer who is submitting for trailer composition jobs on a regular base, and it generates revenue in the “composing for a trailer” or games business.

The typical business model for the composer is that you pitch your services. Be awarded the business and then you need to produce quick results. For the next trailer job, you should get on average 5k as your payment against your time spend and resources used. You need to have that in mind when you look into purchasing this library. The AizerX Trailer SFX Designer Toolkit library is aiming for those composers who are expected to turn around a new score for a trailer within days, rarely weeks.
