i have create two new drumkits.
each kit contain all 64 instruments in the same order as they arranged in the roland mc-307 groovebox.
each instrument is recorded in 6 layers.
this drumkits are real mc-307 groovebox clones. don't wonder about the instrument order and the instruments himself. each set also include 606, 909, and many other instruments. in next time more kits will follow:) (38 kits left). i plan to sell my mc-307, and before this happens, i try to clone most of the sample banks.
