3 What’s the MS-812 ?
The Alyseum MS-812 is an embedded computer Board, using Ethernet network to Convert MIDI
or CopperLan messages to CV and digital control voltages as used in modular and analog
synthesizers.
As the first Alyseum product dedicated to modular synthesizers, the MS-812 offers 8 CV outputs
and 12 digital outputs.
A SYNC24 interface is available as an alternative function on digital output jacks. (Adapter
required)
The MS-812 is supplied ready to use, the actual linking is managed via the CopperLan Manager
software. This freeware tool is also used to monitor the status of other CopperLan capable
computers and equipment. The MS-812 can be controlled and played from any computer
anywhere in the network.
The MS-812 is built around a powerful 32-bit processor offering 120 DMIPS ensuring low latency,
and jitter
High-quality 16 bits converters (Analog Devices) without sample & hold.
