iDrum

Create percussion rhythms without stepping away from your computer with iDrum, an app that simulates a virtual drum set and lets you compose percussion pieces based on samples.

The sound library groups the samples into four categories: hats, kicks, perc and snares. It's also possible to insert custom sounds. The file formats that the program can recognize are WAV, AIF, AIFF and MP3.

iDrum can be used individually or as a complement for the VST, Audio Unit, MAS or RTAS systems. In addition, you can use not just the mouse as an entry device, but also a MIDI keyboard or the one for your computer.
