SD Cards

What kind of SD cards do you guys have? Does it make a difference?

Loading takes a hell of a long time for me (40s), and I wonder if I can get a much faster card? This was loading an "All" file, and I know it's quicker to load just a single sound. But that still takes over 10 seconds.

So, do I need to invest in a better flash card than the $20 2Gb Radio Shack boxing day deal?

See SD cards are the one type of NON-VOLATILE memory.They are available in different classes like 2,4,5,610,15 etc. they are given classes upon their data transfer rates. now, if you want faster data transfer then it is recommended to have the better class device then you are using now days. you should invest in account of the faster use.[/quote]

I once read somewhere that using a smaller card means it can read it faster ... not sure if that's true, I don't see why the KP would have to scan the whole card if it's mostly empty. If someone experiments and confirms it please let me know, I'm too lazy, and all my cards are big (and load slowly)

I did load-speed tests previously with a KP3 and regular and "High-Speed" SD cards. Each was 2 Gigs in size.
The load times were identical.

I bought one that boasted its high speed transfer times and it doesn't seem to be particular quick. Certainly no faster than shown in the Sonic State review. But then, I have no idea which SD card he used.

I also bought a much faster card but the load- and save-time is exactly the same!

It is a bit rubbish how slow it is. However, even if you could save/load while playback continued it wouldn't be as much of an issue but it cuts everything to be able to save or load.

It's like the KPro is saying "WOOOAAAAHHHH!!! You want to SAVE/LOAD something? WOAH! That's quite a tall order. I can't be doing anything else while I do that. I need all my energy to concentrate on getting it right..."

well, if that wasn't the case it would imply it could continue to play the contents of sample banks while overwriting that sample bank with new data, which would require double the memory (one to hold what's being played and one to write the new data to) - but if it had double the memory we'd want that memory to be available for longer samples!.

I guess you could allow loading to a sample bank as long as that bank isn't playing, and allow saving while playing, but I can kinda understand why it is the way it is

Edit: however, I can't understand why it's so slow. I'm not surprised the "high-speed" cards are no faster, but I'm going to try with a smaller SD card

You should notice faster loading times from faster cards.

However, things like 'high-speed', are misleading. For example some USB1.1 devices are labelled 'high speed' because they are faster than USB1.0.

Card speed is measured by the class. For example a class four card is slower than a class 6 card. Currently the fastest you can get is class 10.

That all said, the card reader can be and often will be slower than the card. So whilst you may have a class 10 card, the KP3/KOPro may only be able to read at class 4 speed for example, in which case you won't see and benefit from faster cards. I have a feeling this is the situation with the KP3/KOPro.

Hi mates,

I have few Qs...

What is the Kaossilator Pro reading speed?
Is there no official info?

If I buy class 10, can it work as class 4?

Thank you very much!

I think the reason it takes so long to read and save is probably because it's doing it in real time.

The longer the loop the longer the saving or loading. 4 Loops = 4times the time.
So different card speeds shouldn't matter at all.

Ofcourse I haven't tested my theory yet =)

That doesn't really make any sense.
It's shifting a file of data, it doesn't really matter what playback speed it is. It won't take 4 seconds to write a 4 second loop.

Of course a longer loop would have a bigger file and take longer, yes. But I don't really get what you're on about with this 'real time'.

It writes a file to a card, at whatever speed its card interface bus goes at in terms of (hopefully mega)bits per second.

right, it's not writing to tape!

I have 4 samples loaded on my card and when I go to try and load them all I get is (--) in the screen. No numbers availible. Does that mean it is still loading or that it can't read them? I have tried naming them"01,02,03,04" and also "1,2,3,4" and neither naming convention works. I formatted my card w/ the Kaoss but I am loading the samples directly from my computer on to the card. I am hoping that I don't have to use the editor to do so. Does anyone have a resolution for this? Thank you for your help.
