Music beats

I’ve heard about this later today from my friend, I asked him if there were any apps that could help me make 80-93s type beats. he said this app would help. I tried it and I love this app thank you

Perfect.

If you don’t give this instrument a 5 star rating, you’re either not a musician or a jerk.

It sounds amazing. I need an AAX or AU version for my DAW.

Cool!

Dude, everything here is. Great! I love the old analog sounds, too bad most of it his behind a paywall.

Great app! One request..

Really wonderful and powerful app. One request: can you please make this Bluetooth compatible? It would be so rad to use my stereo speakers as a playback option. This would open up a wide array of possibilities. It works with earbuds but not Bluetooth speakers for some reason. Other than that, I love it!
