With the help of Maarten and Jose Morente I fixed the bug at last.
Indeed the MSX-MIDI was generating interrupts every 5ms and my program was
expecting it at 16/20 ms.
Instead of switching hooks, I fixed the bug with a simple lookup
in the vdp status register, to check if the interrupt was indeed a VIRQ:
IN A,(99h)
AND A
RET P
With this change my program now run on the Turbo-R GT.
Thanks for the help !!
