Philip Rees 2M Midi Merge Unit. Excellent  Condition. 

This is in extremely good condition and was used very lightly in a home recording situation. Lots of uses for this and information below from the Phil Rees site to show just how versatile it is. 

Please study the pictures to satisfy yourself of the condition of the unit and please ask any questions before bidding, thanks.

2M has the power!

As the 2M has a built-in mains power supply it has the power available to drive several outputs! There are thru outputs for each of the two MIDI inputs. The merged data is available simultaneously on two MIDI outputs, so you can drive two MIDI slave devices at the same time. Another benefit of the mains powered unit is that a fast processor with large ROM and RAM memory is able to be used.

The 2M has multiple large data buffers to minimise data loss. To mitigate undesirable delays, it could become necessary to reject some data. The 2M does this gracefully and automatically according to a priority discard system; redundant data is thrown away first. 

Clock interlock system

System Real Time messages (that includes the normal tempo-relative MIDI clocks) and time sensitive System Common messages (including Time Code quarter frame messages, Song Select and Song Position Pointer) are kept in the right sequence and retransmitted at the first opportunity. System Real Time messages are managed by an intelligent interlock system, which prevents clock stream conflicts - see the state diagram above.
