Many applications can simulate the sounds of an electronic piano, keyboard, or computer. However, when it comes down to rhythms and drum beats the issue of them sounding robotic is a problem. Unless you are using Archibald.
One thing that is most popular with is the ability to add a human variation to the program . This allows for a variety of eight different notes to be played. A drummer will never play the exact same 8 notes twice.
Archibald lets you make use of the sounds in 2 ways: SAMPLER that uses many samples to create a real sound, or SYNTH which uses one sample and applies effects, making it more artificial.
Archibald also offers the possibility for users to make their own rhythm so that they can always have a particular sound.
You can download Archibald to get as a virtual drumkit for your computer.
