The software that I love to use for MIDI tracking purposes is "Anvil Studio". It is capable of anything that all-inclusive DAW software can do. However, it's much easier to use IMHO...hand's down! It's also free and very simple to use for quick (or in-depth) recording and editing of MIDI. Plus, there are upgrades that you can purchase that enhance the overall features, including on the fly tempo changes, real-time modulation and pitch bending, and even sheet music/TAB printing to name a few. The upgrades are pretty cheap too. I personally paid $50 for the combo accessory pack, which pretty much unlocks all the advanced editing tools. The $50 is nothing for the value of this program that many people have never even heard of. I love its straight-forward interface. One can use it to edit/write or record MIDI using a musical staff, a piano roll, and even a guitar neck. Another plus, the program is relatively small, so it's any easy download, and once you decide to purchase any of the upgrades or bundle packs, you can update them for the rest of your life for free. I love it! That's my two pair.
