The Roland SP-404 Sampling Workstation is an iconic piece of gear in the Lo-Fi Hip-Hop community. The pad completely dominates the global beat scene and is known to be a powerful instrument in both a studio setup and live on stage. The unfortunate news is the 404 comes with a $549.00 USD price tag and that’s not a little bit of money. What if I told you $3.99 could get you practically the exact same thing the SP-404 gives in function? Well, I wouldn’t be lying.

My Opinion
As an SP-404 owner and a Koala Sampler user, I can say it’s not ridiculous to use both. Chopping samples and running effects feels great on a physical piece of hardware. Tapping on a touch screen alone doesn’t give the same analog satisfaction. However, the SP-404’s pitch function leaves a helluva lot to be desired. I load my samples into Koala, shift the pitch there and resample into the 404. I’ve always wanted to own a 404 and I love using it, but Koala does a great job filling in for the 404 in a pinch or on-the-go. If you have a iOS or Android device and want to save $547 USD, go for Koala.
