I used to use a Windows program where the GUI showed the QWERTY keyboard layout, and you could click on each key and assign a WAV file to it. When you pressed that key, the WAV file would start or stop. My friend, a real scratch DJ, would hook up his turntables and my computer to a speaker system and a recording system of some kind and he would scratch while I sampled WAV samples I had downloaded or whittled down from songs and other files.
I would love to play with that program again and make some “music”, but I can’t remember what the name was and it was something too generic to google–AudioBoard or SoundBoard or something similar, but not named one of those two things.
If someone could help me find this software again, I would owe them a huge debt of gratitude and probably lunch and a drink too.
