Holding the simplicity of eighties instruments and carrying their raw heritage to you, it turns your device into a pocket beat making companion.
I believe that designing a pure interface, simply displaying your machine without any distraction, was the best way to reflect the spirit of the period it was born.

Warning !
A CR-8k is actually very easy to operate and to play with but still tricky to program.
Please refer to corresponding documentation or just take the challenge !

There are a lot of very sophisticated drum machines on iOS but this devs apps are just fun! Hoping for that AUv3 soon! I give him 5 stars just for the fun factor!

I’m adding a star because dev is working on AUv3!

Still looking for AUv3 though! I like this because it gives me the sound and feel of my first drum machines. I have plenty of others but this on (I think because of the workflow) gives me those whacky patterns I got back in the day!

No update yet 😢 OK it’s here! 👍🏼

Dev gets an extra star for quick reply! 😄 Looking forward to update! Happy Holidays!

Not showing up as IAA. ☹️ Need that AUv3 support! I love old drum machines!

Developer Response ,

Hi Anickt, I specially thank you for your interest in drum machines and in my work. You really helped me going further... I am joining Audiobus forum those days where I saw you were really active. I consider implementing Audio unit and Ableton link, let’s talk about it!

Great sounds

This is a fun drum machine app that takes me back to my youth. Can’t seem to get the effects to work tho. Other than that, I’m having a lot of fun with it.

Why don't the buttons move?

Developer Response ,

Hi. I’m actually designing it, let’s wait for the next update. Because it is not 3D, it has to be drawn in a photo-realistic way. Further more, a modern and flat interface will be offered in option soon. Thanks for your kind review, I wish you will love the machine!
