conflicting tasks (usb and serial)

    Jul 03 2006 | 1:26 pm
    Dear list,
    I am running two USB serial converters, (which steer stepper motors) as well as a midi out. The two tasks seem to conflict when simultaneous and hence crash, although work fine independently. I will attempt to alternate the serial and midi output but this seems like a bit of a farmers solution.
    G4, OS X.3.9, doepfer CTM on midi, usb serial converters ( 2 serials on a usb bus, midi direct from laptop,
    Any ideas much appreciated
