Many learners these days prefer to use their own laptops on our courses for things like getting help customizing their set-up, and they have their project exactly as they left it in class to work on at home. So we made the course more affordable, but added a $75 supplement for learners who wish to hire an iMac loaded with software. Please ensure you book an iMac when you book your course if you need one. Controller keyboards, and headphones are provided for everyone.

Our Testimonials

As a songwriter/producer I relied heavily on engineers for recording and mixing if I wanted to get my tracks sounding like masters. I always wanted to do more myself but struggled to learn anything watching an engineer zip around at 1000 mph! Then I found Garnish and did their course. It was exactly what I needed, we covered everything I was unsure of in the past from using buses properly, EQ, audio compression and using specialist mastering plugins. Everything was explained and demonstrated in a way I understood. I never thought I'd ever be able get such great sounding tracks doing everything myself.

Ben Cullum

The course was helpful to me to gain a better understanding of the specifics of how to make my mixes better. Explaining specific concepts about compression, reverb, delays, EQ, etc. that I never really had a good grasp of before.

Cyndi Lee

Even though I already know about mixing and mastering, being here gave me a different (in a good way) concept of the knowledge that I already have. Also I learned a lot of new things about mixing and mastering, that will definitely help in my career as a Music Producer.

The instructors are terrific – They are very attentive to the needs of the students – as well as our individual backgrounds and goals – and that makes the learning more personalized. They are all professionals with diverse expertise and have the industry experience to teach not just the mechanics of the software – but the real-world applications and circumstances. I came to GMP in the hopes of finding teachers who were able to give me a strong exposure not just to the the software (which they did very well) – but also to all the various ways the software is intersecting the other music processes and issues (recording, musicians, writing, industry issues, marketing, etc.). For a detailed software class, GMP offers a very “holistic” experience in which to learn and engage!
