Sam Battle – well known for his ‘Look mum, no computer’ series of videos, instructions and musical performances with modular synths, did a series on the Elektor formant synthesizer.
Sam pointed out that a lot of electronics magazines from the 70’s and 80’s are a good basis for starting your own DIY Synthesizer Project.
Below are some snippets from his video’s on the Elektor Formant and links to his website/youtube video’s. All (c) Sam Battle/ Look mum no computer’.
