For those who are stepping into DTM, we will introduce Kontakt free sound source, information on free distribution sound source for a limited time, and recommended free sound source. Among many DTM sale sites, this site is particular about (1) usability so that it is as easy to use as possible when collecting information. (2) In addition, our motto is to introduce as much free distribution information as possible for a limited time. We are also working on creating a database of recommended Kontakt free sound sources.
