    The circuits presented in these pages work well and can be used as is or as good starting points for your own designs. I encourage you to breadboard them, experiment with them, and certainly to improve them. I have built and tested most of these circuits and they are in my (ever growing) analog synthesizer.

    Although I can (and do) claim credit for many of the ideas in these pages I must acknowledge that many synth developers have come before me and I have learned much from their ideas and circuit designs (see Acknowledgements).
