The MPD/MPK/LPD controllers are all class compliant USB/MIDI devices. That means that they do not require a driver to be installed. This is convenient for two reasons, one the obvious not having to install anything on the computer to run the devices but also so that devices can be used with a DC power pack to play external hardware like sound modules and synthesizers. So even if you're totally software it's still nice to know that an MPD/MPK/LPD will work in conjunction with any MIDI enabled device going back to 1983.
Built in PC motherboard audio, generally made by Realtek and Soundmax run on Direct X or WDM audio drivers. Both are fine to playback media players and video audio but are not up to the task of low latency audio/MIDI operation.
What that means is using standard Direct X/WDM drivers you will have a terrible delay from the time you press a pad/key to the time you actually hear a sound triggered. It is so bad it makes playing musically basically impossible.
Also depending on the CPU/RAM and possible background processes you may also have problems with scratchy/distorted audio or dropouts where the whole song stutters or cuts in out as the audio driver is taxed too hard to update the sample buffer for clean playback.
Years ago Steinberg created the ASIO driver protocol to use instead of Direct X/WDM. ASIO by design "skips" layers of the operating systems topography, the same layers that cause Direct X/WDM to be mostly useless for audio work. The ASIO driver protocol "talks" to the computer at a lower level than the other drivers and has a more direct line to the silicone, so to speak.
Most external interfaces and the less prevalent nowadays internal PCI/e cards include their own ASIO drivers. Usually the better the interface the more likely a custom ASIO driver was written for the interface, with performance increasing as you go up the price tiers.
If you have no interface there's still a solution. Michael Tippach wrote the free ASIO4All emulated driver for built in motherboard sound PC's.
http://www.asio4all.com/It is not a true ASIO driver as there is no true ASIO compliant device involved, just your motherboard Direct X/WDM being "tricked" into using lower level instructions and then the performance gain in audio/MIDI latency that ASIO delivers.
On a Mac, Core audio numbers are better out the box as the driver was written with low latency in mind.
On to the MPD26. The first issue is that EVERY MPD ever released has the pads mounted too low. These units can not be played with reliable velocity variation like a real MPC or a better made MIDI controller. They all contain actual MPC pads, but again they are mounted wrong. You can engage the "Full Level" button but then every hit you trigger is at MIDI max velocity 127 and is robotic and devoid of any dynamics.
You have to either take apart the unit and apply silicone to the bottom of the pads, do a similar operation with small stickers stacked on the pads bottoms or buy these for $45.
http://www.mpcstuff.com/akmpcmpdthfa2.htmlOnce you do the silicone or buy the fatter pads the sensitivity is fine. But it's insane Akai used the same flawed mounting a total of 9 times on the MPD/MPK series.
If you still want an MPD after all that I would recommend spending extra and get the MPD32. It may look like you only get 2 more faders and 2 more knobs and 8 toggle buttons, but the most important thing is you get 3 bank switches for the faders/knobs. On an MPD26 you only can assign 12 controls per preset. On the MPD32 you can have 78 assigned controls per preset.
MPD's have good built in presets for Live/Drum Racks and Reason. (On Live Racks and Reason Combinators the 8 MPD32 knobs aotumatically go to 8 macro knobs on the devices for example).
Here's a list of tweaks to get a Windows computer more suited for audio. (Chart explains the various things you could disable that you may not need to slim down the OS processes and have more juice for audio work)
http://www.blackviper.com/2009/10/01/bl ... er-tweaks/This is a good place to get more familiar with the basics of home audio. But having already asked about interfaces and USB plug and play it sounds like you're already off to a good start.
