This cookbook is very much oriented towards the beginning synthesist. 
The patches are all very simple and use a standard template: 2 VCO, 1 
LFO, 1 LPF (either 4 pole or 2 pole), 1 VCA, and 2 EGs (for LFP and 
VCA). You don't need a modular synth to recreate any of these 
patches, you can do them all on a Pro-One or MS-20. Using a standard 
template to work with any synth would normally be quite problematic, 
but the author has thoughtfully included a calibration section (and 
included an audio CD) so you can figure out which knob setting 
responds to 1.4 kHz on your filter (for example). Someone with a 
modest modular synth would likely go much beyond the simplicity of 
these patches.

So is it worth buying? Depends on who you are.

Collector of all things synth: yes.
Beginning synthesist: yes.
Intermediate synthesist: maybe.
Advanced synthesist: no.
