I've played piano for a number of years and did some classical composition classes (i.e., score writing in Sibelius) while at school. The road block I've hit at the moment is that I can't find a good way to learn sound design / how to properly use synthesisers. I really love the sounds you can get out of synthesisers, and the main thing I want to do with my audio setup at this stage is "play" digital / electronic music from my midi keybard.
I've managed to pick up on the basics of subtractive synthesis (playing with single/double oscillators, lowpass filters and LFO). I just really don't feel like I have enough knowledge about sound design techniques to get creative with it.
I'm not really in the market for a paid course, so I'm wondering if anyone can reommend good (free) resources to learn the basics and follow on to intermediate sound design?
