Built in the studio
Small tools for expensive minutes.
I've built these apps to solve practical production bottlenecks: preparing files for mixing, editing drum samples, creating Trigger Instruments, and creating IRs. Each app is designed to take a slow, manual process and get it done in a fraction of the time. - Forrester
Production & mix credits include
Karnivool / Bear McCreary / Animals as Leaders / Tesseract / Twelve Foot Ninja
