On an Intel Core2Duo 1.83GHz 4gig Notebook running Windows XP sp2.
I run MyDMX as well as Nuendo with MOTU Firewire interface and Edirol USB MIDI interface.
MyDMX performs as expected when it is the only program running. All channels work and software performs smoothly.
When running MyDMX at the same time as Nuendo, I get spikes and clicks and dropouts in my audio. In order to get rid of the audio problems I have to make changes in Nuendo and the MOTU interface that leave me with a terrible latency problem which is unnacceptable because I use Nuendo for Live Keyboard Mixing.
So.... I found that if I run MxDMX in compatability mode for Windows 98/ME my audio problems go away and MyDMX runs fairly smoothly... except..... !!!!
Channels 1-4 do not send good DMX data which puts my first fixture in quite a bind.
Reading another thread shows that simply shifting my fixtures up 4 channels will set me up for a complete reprogram of the show. (which is unthinkable, so instead i may just move the fixture address to another place in the DMX channel spectrum)
So I thought I would check here first to see if there was a fix/workaround for this problem.
edit: additionally, I have not tried my terminating resistor at the end of the DMX signal chain yet...
