I'm confused. Are you going to use MegaDrum over USB or not? From what I understood from your posts you don't want to use PIC and USB.

Oh no a big missunderstanding!It's my fault!I am sorry!I should have mae it clear from the beginning!
I am going to use the PIC and the usb but not from the start...I will start working on MIDI and if i am satisfied i will continue with the usb board!
I just wanted to know if i can programm the IC first without the bootloader using my ISP,test it and then( if everything is going well) programm the bootloader and start updating through usb!That's all!

You can certainly do all of this just as you described here.

now that we can understand each other should i leave the fuses as they are? this won't cause problems to programm the bootloader later?

Leave as is! You WILL be able to program the bootloader later.
For no apparent reason I have a feeling you still will have doubts even after this

I don't have doubts now that i am sure you understand what i want.Its just that i avoid to change the fuse bits if i am not sure!I recently destroyed an Atmega32 trying to programm it and they are quite expensive for me to do such mistakes!
but don't worry!For more problems i will be back!....soon!

Thanks a lot!

If it's just incorrect fuses, you can recover it. viewtopic.php?f=3&t=42&p=278
