Pulse Code consists of two members. Twin brothers, Louie and Billy Iturzaeta. Pulse Code is a labor of love for us. We work on apps in our free time while still juggling careers and families. We are passionate about electronic music and the instruments that create it. Our goal is to spread this appreciation to new and inspired minds.

We would like to thank our families and friends for their support of this project.


Pulse Code started in 2005 with the homebrew project PSP Rhythm on the Sony PSP. PSP Rhythm started out as a simple drum machine and synthesizer. Over the next few years, PSP Rhythm developed into a popular underground music production application.

In 2008 Pulse Code officially began developing on the iOS platform. Since then, we have learned a great deal about sound design and electronic music creation. All of this knowledge and experience is showcased in our greatest synth yet, modular.
