Matt I did not realize how good of a refill that Free Flight WTF refill is on the Propellerhead site was. Its got some quirky and really good drum sounds. The flight line samples are incredible. Man I overlooked that for years and decided to get it today and man I was mad that i hadnt got it earlier. If you are looking for some quirky drum sounds, that is a refill everyone can use. I didnt make it but i had to put a shout out about it.
