Drum Machine is a sketch I made to test out the AudioSample class in the audio library I’m working on. It is a really simple grid-style drum machine. There are three rows of sixteen buttons each. The rows are, from top to bottom: hi-hat, snare, and kick drum. The buttons correspond to sixteenth notes. So, you only get one measure to make your sick-ass beat. You can change the tempo by clicking in the BPM box and dragging the mouse up and down. It does a pretty good job staying in tempo, even though I didn’t do anything particularly fancy to calculate beat length.
Unfortunately, there is no way to load or save beats that you make and also no way to choose different samples. Perhaps these features will be added in a future version. For now, it’s just a fun little sketch to play with.
