As a salesman in a modular store I have tried and used many modules but no modules have convinced me as much as the ACL modules. I have never used a faster and more precise envelope than the Envelope X3. The DISCRETE CORE LADDER VCF sounds so incredibly good and the Sinfonion has become the heart of my modular system. For a long time I have been looking for modules with such quality, functionality and sound and then I found them at ACL. Thanks for it!
