The Music Lab Pak from Roland is part of the company's Media Production Bundles and is especially useful for educational situations where audio stations need monitoring and control. Connection to the host computer is achieved with the DUO-CAPTURE USB interface that provides two inputs and two outputs with 24-bit resolution.
A 49-key keyboard controller allows for inputting information and performances into the host software (not included) and monitoring is available via either the MA-15D powered 4" speakers or the RH-5 headphones. The bundle is also highly suited to a project studio where audio software and a computer are already available.
