I run programs in which I have an Xbtimer interrupt handler which outputs MIDI data (by writing directly to the ACAI register, not TOS or XBIOS) along with a revectored MIDI input routine. Occasionaly 24 bombs drop across my screen, indicating spurious interrupts. Does anyone have experience in clearing these up. As far as I know, I have obeyed all the rules. The errors do not occur if the Xbtimer runs and the MIDI sent to the ST. I might try disabling the Xbtimer while there is MIDI input but who wants to do that. Jeff Beer, UUCJEFF@ECNCDC.BITNET
