Mopho Lock Up Issue (was Re: Newbie: understanding Hex & SysEx??????????????

2010-03-08 by Rob

I did sell the Mopho last week

(1) twice, one is fine
(2) no
(3) PX7 midi out A to Mopho
(4) The Command Station is providing the clock.  I thought you couldn't use the PX7 as a sequencer and use the Mopho as the clock.
(5) I don't know how to send bank changes from the PX7 but I send bank & pattern changes from my Novation Remote and the Mopho is fine.

If I hold the "push it" button on the Mopho (causes it to sound) while pushing stop twice (on PX7) the Mopho doesn't freeze.  I did sell the Mopho last week.

The XL7 spits out a lot of MIDI data when you press stop twice (as I'm sure you're aware from looking at MIDIOx...)  It may just be "confusing" the Mopho.
