its has 1.9.1 installed as far as i know but will confirm.
I have attempted to diagnose the problem some more in the last few hours but this has led to further oddness.
I tried every chain combination including just driving the CZ from the XOX.When you slide a note on the Xox the CZ locks up. More often than not, start stopping the XOX will result in the same lock up on the CZ.The XOX seems to be running continually with no hang ups or odd notes on its synth.
When sequenced from a DAW arpeggiator/step sequencer the CZ1000 displays the same prob as when driven by the XOX,ie midi input trips out ,a note sticks on the CZ,and continues to play after stopping the clock.I then need to reset the CZ patch to continue.
If i am sequencing a VSTi from the Xox , when start /stopping the clock ,I get the same hung note problem on the VST.
The Xox causes similar behaviour when sequencing the FAT 383,when you slide a note on the Xox the midi locks up on the 383.
I have tried changing midi leads.
I think my studio is haunted or is just bad combination of gear,the Cz has weird envelopes and midi,the XOX isnt a rock solid machine and the FAT 383 is basically rubbish.Will try some other XOX /synth combinations later when I dig out the bass station and D110.
Thanks for your input guys.
Sorry for the head ache.
