I turned active sensing off, midi clock data off, I turned everything off. Nothing helped.

I'm using a Roland XP 80 and a Yamaha p 80 as masterkeyboards and a Midi Mate USB midicontroler (which costs about 30 Euro's and saves you a lot of headaches). I do now what I do best: making music again ...

I solved my problem: I bought an USB-midi-interface and use that instead...

I'm reopening this topic because the problem is still there. Now my computer doesn’t freeze at random moments, but the freezes occur (sometimes) when I trigger a midi-note (in combination with a VST-instrument). When cubase is triggering these notes it's all ok, so it's a midi-trigger-problem. Midi ...

Also disconnecting pulsar midi source vs. sequencer destination does help ...

I tried all that, but still sometimes my computer freezes. It could be a midi problem, because when I disconnect my masterkeyboard (which always is sending midiclockevents) it seems to be stable (it's always difficult to be sure).

I do have Cubase SX3 running with a few vst-instruments, but ...

I found out that the problem also occurs without Cubase SX, so that isn't the problem. I mean by freezing, that the computer doesn't respond to anything anymore, I have to reboot the hard way.

I don't know what you mean by "IRQ allocation for Pulsar". Do you mean the virtual devices which are ...

Hi there,

I'm using the old Pulsar 1 card with Scope 4 software running under Windows XP. The combination with Cubase SX 3 makes my computer (Pentium IV 3.2 GHz) freeze at random moments. Does anyone have an idea how I can fix this?
