LSSP is an abbreviation for the Large Scale Sequencing Project – a collection of Adroit Synthesis modules designed to help you compose music in a modular synthesis environment.
LSSP runs on both Windows and Mac computers but is only available as part of Cherry Audio’s Voltage Modular.
LSSP XL is the entire suite of modules. LSSP 101 is a specially selected subset.
The diagram below shows an architectural overview of LSSP.
