Hi all, I've designed an android app that can create OP-1 drum kit .aif files and make back ups on the go. It works with an OTG enabled android device.

It is a highly updated version of OP1DKU I made last year. I have decided to sell it as I have put tonnes of work into it.

I will be adding OP-Z support and more features in the near future.

Find it here:

Hope you like it!


  • Great work! thank you.
    Have you thought about putting a synth sampler option in there? for OP-Z guys ;)

  • The power of android! I wish the new ipad pro was even capable of doing this. Amazing work. I bought a copy. Very cool.

  • Metske this is wonderful! I came hear after having some issues with the PC Drum Utility and this was a lovely surprise to find. I'm looking forward to testing this out and would love to provide feedback if you'd like.

  • @mcslambley as much feedback as possible would be greatly appreciated! It all helps me to provide a better app!
