If you know modular then you'll know Mylar Melodies! Youtube chap and modular mogul - he's been playing live, demonstrating his setup, and interviewing fellow bleepers for many a year. In his latest video, he goes through all you need to know to get started in modular, answering such imperative questions as:
What modules do I need?
How do you pick the best modules?
What case size do you get?
How does power work?
Why are modules so expensive?
Do I need an output module?
How do I plug modules in safely?
All you need to know to get started! He has a fine youtube channel for those into, and out of modular - as well as hosting the fine Why We Bleep podcast.
