Hello! I shared this several months ago and was really motivated by a lot of the great feedback I got. Since the last post, I've:

• Made some performance upgrades, so there should be less stuttering if you have a pattern with a lot of beats.
• Added the ability to randomize more granularly -- you can set specific octaves to change when the pattern starts, which lets you do things like fix a drum groove and a bassline while a melody is randomly generated.
• Made it so that DrawBeats can play when it isn't the active tab.
• Added more granular options for tempo and swing.
• Added some animations.
• Added a simple recording functionality (non-mobile only atm).

For the holidays, here is a chiptune version of everyone's favorite Christmas song that I threw together. Thanks for checking it out!
