Storing and transmitting raw midi with a pic

Hi,
I'm trying to design a device which stores the MIDI info generated when a simple chord is held on a keyboard (via a UART on a PIC) and then transmits the info back to a MIDI device (such as a keyboard) which should then play the chord continuously until a reset command is sent out.
Can anyone envision any problems i will have? A concern of mine is that problems will arise due to the 'snapshot' nature of the saved data. This means that no 'note off' messages will be saved etc.
I need to know if it is possible to simply store the binary that is created whilst the chord is being held, and simply send that message back to the IN port of a midi device. If the same chord originally played is reproduced- it will be a success.
(I what the reproduced chord to be free of time based effects or messages- the chord should sound until it is manually terminated. The programme, channel, velocity and note values need to be stored and reproduced)
Any help would be greatly appreciated and appropriately credited in my final report.
Many thanks
