The Voyetra V-24s was one of the very first multi-port MIDI interfaces 
with SMPTE and MIDI Time Code (MTC) generation available for the IBM-PC/AT.  
It featured 2 MIDI Inputs and 4 MIDI Outputs, along with full MPU-401 
compatibility.  

The V-24s used the V-22 host card to communicate with the host computer 
through the IBM-PC's Industry Standard Architecture (ISA) peripheral bus.  
The V-22 also provided the necessary connections for the daughtercards that 
enabled the V-24s system's MPU-401 and SMPTE generation functions. 



The V-24s was introduced in 1991 and went out of production in 1995.
