Happy to announce that
version 1.3 of ReefIt Bass just landed in the iTunes store.
You can now record your beats!! I also spent a good while adjusting the tap response. I ended up using OpenGL for the UI. OpenGL provided a nice way to make hits. I had previously used a CSLayer that worked but never in the responsive way I wanted. I played around with a particle generator but ended up with just a few "sound" rings when you hit/touch. I also removed the explicit split functionality - where 2 sixteenths would play on one drum and force you to another to play the other half of the split. That prevented a whole bunch of other combos.
