The Yamaha DSP Factory works as an audio card and provides additional mixing capability through a software environment into Cubase. The Creamware Pulsar works as an audio card and provides additional DSP as VST plug-ins. The Universal Audio UAD-1 is only a DSP card to run plug-ins in VST format. TC Works PowerCore card is also a DSP only card for running plug-ins. These cards only work with each company’s plug-ins and will not run Native based plug-ins.
