Dr Drum beat samples. Make beats on your PC or Mac
In my experience, more affordable beat makers are low on options for tweaking your sound. Dr. Drum has managed to break the mould by providing options for adjusting the volume of each track, emphasising different frequencies and panning different elements of your beats into designated speakers.
