• The Patchwerk Check My Mix service is an opportunity for artists to bring in a track that has been mixed or mastered elsewhere and listen to it on top-notch studio monitors to get a good feel of what the record actually sounds like. It allows artists to check if their levels are proper and make critical mix decisions in a professional studio environment. The service is offered at a discounted rate in 30-minute increments between 10 a.m. and 6 p.m. It is for listening purposes only and does not include an engineer or recording time.
