Welcome to Seb's Synth-DIY Pages
These pages are my attempt to give something back to the synthesiser DIY community. The projects listed on these pages would not have been possible without the help of many knowledgable people who share their projects and expertise on their websites and on the synth-diy mailing list. So thank you all!
Listed first are completed and fully working projects, then below are my 'under development' projects which over time will get updated on this website. No doubt the list of 'under development' projects will also grow over time :)
Feel free to get in contact if you have any questions or comments, or indeed if you spot any errors! You can reach me at:
