Bought this a few minutes ago…

I’m already super impressed. This is a FANTASTIC piece of design - really - it’s beautiful and useful in so many ways (especially - simplicity leads to victory) and as of right now the only thing I’m missing is a sampler included with auto slicing via transient detection. Well ok, ADSR would be nice too and ESPECIALLY 3D Touch support for phones that have it (instead of vertical “velocity” for the pads). As a last suggestion that is ultimately not as relevant since we can create kits, is, please add more acoustic kits. I actually really like a few kits here, but I’m just not an electronic guy so most of them will probably not see much use by me.

Regardless, this is a fantastic AU and I will be using it a lot from now on. Thank you! Will definitely keep an eye on this dev! 🥸

Hi Enrique, thanks for the kind review! So glad you like the app. Thanks for the feature ideas, too. We will keep them in mind for future updates!

Just Get It

More useful than it may appear at first (I was initially put off by the colorful pads, which makes it look like a toy), but I found it quite useful for the variety of drum kits it has and the available modification options.

My big ask for the developer: Please bring this to macOS (desktop) for M1 Macs. My workflow involves developing rough ideas on iPad Pro, then finaling on desktop and there are no fast and easy replacements for this app. Being able to use this as an AU plugin would be a tremendous timesaver. Thanks!

Developer Response ,

Thanks for the review! We've talked about bringing SDS-x to macOS but there are a lot of specific touch-based interactions that wouldn't translate super well to desktop. That being said, it's not out of the question!


Beautiful sounding

Loving this bad boy great samples btw was hoping you could add adsr control or am I not seeing this ? I like that you are offering different forms of payment to use the app ie monthly sub, yearly, and outright buy. I chose the later I don’t like renting personally. I like how you make use of the full size iPads with the larger screens one feature suggestion could be different midi/sound settings around the 4 corners of each pad when in this mode think hardware kieth McMillen quneo. Definitely like the drag and drop sample support as well. Glad to see you are the hardworking type of developers thanks.

Developer Response ,

Thanks for the kind words. There is no ADSR control at the moment, but we will keep it in mind for future updates!

Pro tip: One way to get multiple sounds per pad is to load two samples into the pad and then change the sample mode to "velocity switch" (VSW). Then go to the global settings and make sure the velocity mode is set to "top." The bottom of the pad will now play one sample and the top of the pad will play the other.
