I got myself a small keyboard to use on the go. My choice was the Akai LPK25 because I found it very worth the price. According to me it is high quality and very affordable.
Together with my android phone and Caustic it makes one of the smallest DAW´s available.
As you know, I like to hack things. And wether you want to add a sound source to it or have to perform a repair or whatever… i found no pictures of the inside of an LPK25. That if something is a quality sign, isn´t it?
Well, pictures will be needed in the end, so my idea was to put some of them right here.

I also found a fantastic software called “Ctrlr”. Have a look at their wesite.
This made me able to write my own interface to control the settings for the presets on the keyboard. Ctrlr is multiplatform so now you (and I) can control the LPK25 from Linux to.
Here is a link to my “panel” as Ctrlr calls it.
Please send an e-mail if you have questions.
