Hi Larry,
it did take me a few weeks to do the original sorting of styles and naming them, but with the list, it probably would only take a few days. If I were to start from scratch( armed with the list), I'd be inclined to maybe download the .cst's in smaller batches and sort them as I went.

Having had a closer look, I've come to the same conclusion that it doesn't appear that midifiles can be loaded to the sd card and read by the KN. Of course you can load anything from a computer to an sd card ( via a card reader), but that doesn't mean the KN7000 will recognize it.
I suppose the midifiles would have to be loaded into the KN and saved as songs instead.
I actually have a few of the Technote Play Along series of disks, which comprise of styles as well as sequencer parts (songs). I downloaded them to my SD card. It was interesting to note that loading them via floppy took quite some time, whereas loading them from the SD card only took a few seconds.

Glad to hear the instructions and list are helping some members. Hope you were able to make sense of them.
best wishes
Rikki
