DM–307 comes in a cca. 4.5 GB bundle of various drum kicks, snares, hihats and sound effects. It is in general a drum machine made for Kontakt with all the possible effects that Kontakt comes with.
There are thousands of samples split into 7 main genre styles which are part of 3 larger groups (Kits, Loops and Kit grooves). It appears that Heavyocity went for a broader spectrum of users now, offering a lot of content for EDM producers as well as film composers. Here is a brief overview of the 7 main styles.
1. Drum N Bass
2. Dubstep
3. Electronic
4. Hybrid
5. Rock
6. Latin Organic
7. Industrial edgeInside each category and subcategory are all the patches you will ever need. Heavyocity really did a good job on placing each patch into the right category. In terms of content you can compare DM–307 to Native instruments Battery 4. They both share around 4 GB of samples and both enable you to modify each sample but unlike Battery you cannot add your own to DM–307. This of course isn’t Heavyocity’s fault; it is just the limitation of Kontakt and its scripting engine. You can change midi patterns inside the Kontakt which is a nice feature. If you own a full version of Kontakt than you can refer to Studio Drummer to understand what midi patterns can do. Read the full review.
