The differences are mainly in three areas: number of channels, synchronization, and expansion capability. Dakota includes 16 channels of ADAT lightpipe, as opposed to WaveCenter/PCI's 8. Dakota also includes a SMPTE reader/generator and ADAT 9-pin sync as standard features. Dakota also has several expansion options for customers with larger studios or specialized needs. The options include:

1.Montana: adds 16 additional channels of ADAT lightpipe, along with a combination video/word clock input, and ADAT Sync out.
2.Sierra: a high-performance rackmount 8x8 MIDI interface, with dedicated 1/4" SMPTE input and output.
