Sunsine Audio was founded in 2012 by Fletcher Kaufman and has provided content for numerous award winning apps (including Gestrument, which was awarded the City of Stockholm Innovation Prize 2012) as well as working with some of the largest instrument manufacturers in the industry (including Waldorf and Arturia) and recently started a line of boutique hardware effects, hand built and designed in the USA. Fletcher writes for the electronic magazine Apptronica, producing a regular column on sound design for this mobile music oriented publication.

"I have never been more excited for a preset pack! BitWiz (mini-review) can make some amazing tones, but I've never been able to meaningfully get my head around the Bitwise operation that drives it." - discchord

Q: Why are your products so cheap, is the quality inferior?
A: No, we provide professional sonic solutions for quality minded producers and musicians. We're broke ourselves and don't believe you should have to sell your firstborn child to make some sweet tunes. We hope you agree!

Q: Will you accept my firstborn child in exchange for samples and presets?
A: No, that violates international trade agreements.

Q: Are the products available for immediate download upon purchase?
A: Yes, but occassionally some user's have reported that the automatic email gets held up for a short period of time, please be patient and contact us if it has been more than a few hours time.

Q: Why is the sky blue?
A: A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.

Q: Can I download these files directly to my i-Device and begin using them?
A: Some apps support "Open In" allowing you to do this, but we recommend utilizing iTunes for transfering all of our iOS products. 

Q: Are there restrictions on how many times I may download a file or for how long it's available to me?
A: No, we no longer restrict time or amount of downloads!

Q: Are these samples/patches royalty free?
A: Yes, when you purchase any product from us you purchase a license to use this product in any original composition or song, 100% royalty free. That means if you record a hit song with one of our products, you owe us absolutely nothing.

Q: Can I give these samples/patches away, or resell them?
A: No, when you purchase a product the license belongs only to you and is not transferable. You may not give them away or share them on the internet or in any other way.

Q: Do I have to mention Sunsine Audio in album credits, etc. if I have used your samples/patches?
A: Absolutely not, but it is appreciated, and magical fairies will follow you everywhere, sprinkling pixie dust on all your beats!

Q: I have a concern or question not answered here, what should I do?
A: Please feel free to contact us -
