Title: MIDI-OX Slows down when getting a lot of input??
Post by xlazyx on Oct 22^nd, 2002, 8:21am

Hey!

I've created a small script in VB for my midi controller and Cubase SX. You can make cubase SX send out MIDI info about levels on different channels, and this is used to controll LEDs on my controller. Problem is, when i press play in SX and it starts sending out these messages for 8 channels, MIDI-OX increases it's CPU use very much, and if I then turn a knob on my controller while SX is playing the MIDI OX cpu increases even more, so much that the knob turning is really lagged and will eventually crash SX

So, is there a bottleneck in the COM interface or in MIDI-OX somewhere?

I will put up a link to the source for my VB script so you can see if there is a design flaw there causing this.

Thanks

Tor Arne

The sink method of scripting just uses COM and wasn't really designed for dense MIDI data. You could try changing the method for getting MIDI input to polling.

Hmm, ok, ill try that. I also read something about Midi Yoke NT causing this, I'll check for that too. Will report back if the problem doesn't go away ;D
