“Drum Pro comes with 20 drum kits and the sounds of 9 vintage rhythms boxes (including TR-808 and TR-909). Each element is mapped to a virtual pad, controlled externally from your MIDI keyboard or drum pad, and has its separate volume and pan settings. You can also adjust the attack, decay, sustain, release and overall volume and reverb is integrated.
Drum Pro is free, you can then complete the audio collection with pay for expansion packs, but you already have enough to spend a good time.
Drum Pro is a plug-in VST and AU for Windows and Mac OS X 32 and 64 bit”
