We will share these updates with our developers. Also, our updated Splice Mobile Sounds app has updates to the core CoSo functionality, which we are now calling Create. We recommend installing the Splice App to use the latest version! ### 4/5 — More Genres Please *2023-12-15* Sooo much potential! Please expand to other genres…Rock, Goth, Reggae, Future Pop, Club, Alternative anything, Country, Metal, RnB, Cinematic, Industrial….get more specific. Again-the most unique and in-the-times app, but please don’t stop here-get your R&D team and coders to make this tech the go-to for instant inspiration. Thanks to the team so far…go from Alpha-Beta…to THE app you can’t live without!!! **Developer response:** Thank you for your review! We are so glad to hear you are enjoying CoSo. We are always looking for new genres and styles to add to the mobile app. It's helpful to have users like yourself letting us know what we can do to improve the CoSo experience! ### 4/5 — Love but pitch control would be niiiice *2023-11-02* That’s it, I like it! But I wish it had pitch control. **Developer response:** Thank you for your review! We are glad to hear you're enjoying CoSo. We will pass along your idea for pitch control to our developers. Please let us know if there's anything else we can do to help! ### 5/5 — industry level beats *2022-11-21, version 1.4.2+2133* i make beats like drake,kanye,lil yatchy etc this app is amazing for me and my future when i start my music carear this app will help me alot thank you devs ### 5/5 — Amazing! Please don’t ruin it! *2022-10-29, version 1.4.0+2091* It’s perfect! ### 1/5 — Hate the small play button! *2022-09-20, version 1.3.6+1876* Make the play button bigger! Every time I just want to play a song by pressing the play button, it instead goes to edit mode. You really need to be pinpoint accurate to press the play button. Please make the play button “click area” bigger. Would solve lots of misclick problems. **Developer response:** Hi L-Rey, I'm really sorry that you haven't felt heard by our team!

Splice Customer Experience ### 4/5 — Its good but needs work *2022-09-09, version 1.3.6+1876* Needs more work keep working on this splice… ### 5/5 — Amazing! *2022-08-30, version 1.3.6+1876* I’ve been using this app for a couple of months now and it’s amazing. The latest update that allows you to adjust individual volume is an awesome feature. When will the Export to Ableton option be available? I’ve been waiting on that feature to really take full advantage of this and implement it into my workflow. Thanks for the amazing support and updates! ### 3/5 — Good but minimal *2022-08-13, version 1.3.3+1592* Great concept, however I wish I could use this app to put together drum kits from splice. It will not allow me to listen to different kicks, or snares, or hi hats for example. It only stacks loops for now, which is fine if that’s what you use splice for, but if you use it build kits, this will not help you. ### 5/5 — Great for generating ideas *2022-07-06, version 1.3.3+1592* Love using this app to generate new ideas on the go. It’s nice to be able to export them to the desktop app so you can build bigger structures. Love the spontaneity! ## Frequently asked questions about CoSo by Splice ### What does CoSo by Splice do?
