Cubase VST & "Midi Out" on the Delta 1010

[rio452001]

I just updated to a Delta 1010 from a Delta 66 to get more simultaneous inputs-- if this is a silly question, forgive me, but I don't see anything helpful in the manuals or in previous posts

Here's the issue:

I'm using a P4 1.5 Ghz with 1024 RAM, and Windows 98SE as the operating system.

I've noticed that the "Midi Out" light at the front of the Delta 1010 rack unit is always flashing (in time, naturally). I wonder if this is normal, or whether this function can be turned off or otherwise disabled?

The reason I ask (this may sound weird) is that, when I try to use the lowest buffer setting (336, I think) to get the lowest latency, I get pops & skips & other noise that seems to be happening in time with the "MIDI Out" signal

if I go up to the next buffer level (508 or thereabouts, I think) it's fine, but the latency is about 13 milliseconds, which I could live with if I had to, although I'd like to get it down further

I'm wondering whether the MIDI out signal is somehow interfering with my ability to record at the lowest buffer setting, and whether I can't maybe get better latency if I can turn off the "MIDI out" signal?

If I'm really barking up the wrong tree, tell me gently... but if there's a way of turning off this "Midi Out" signal, I'd be obliged

best regards,

Rio

MIDI should'nt effect audio latency. You should be able to get a lower latency though. The bit depth and sample rate of your Cubase project will effect the latency. You should be able to get below 10ms latency running a 24 bit/48khz project without clicks and pops.

Your system configuration will have the biggest effect on how low you can set the latency. Checkout M-Audio's site for info on proper driver installation and configuration.

Hi Travis

thanks for your message

I'm recording 16 bit & 44100-- does that make a difference?

should I be going 24 & 48000 instead? would that be better? if I then master & burn to CD, do I "dither"?

sorry if these are amateurish questions, but is there anything else you can suggest on configuring my system to get lower latency?

thanks,

Rio

This is Home Recording. Questions like that are expected. Yes you dither. Now if this was recording.org you'd be beaten to a bloody meat pulp. Those freakin elitists.

Your bit depth and sample rate settings are fine, 24/48 is just for higher quality. Did you get a manual with the 1010? Did you install it as the manual directed? M-Audio has a bunch of info on their site on installing and configuring your 1010 and pc. Check it out and let us know if you need any help after that. Also, check out www.musicxp.net. It has alot of good info on configuring a computer for recording. The site is geared toward Windows XP but you should find some good info there that pertains to 98 SE.

You'd think. I have had some weird issues with MIDI timing when using the MIDI outs on my Aardvark Q10. Theoretically one shouldn't bother the other, but then again, when things run off of the same PCI bus one never knows what can happen. This is also dependent on the motherboard.

If MIDI out light is flashing on the Delta, and you're not sending anything MIDI out of the MIDI outputs on the Delta, it's possible that you've got MIDI sync turned on in Cubase. Go to Transport -> Sync Setup and make sure that the MIDI sync checkboxes aren't checked. I'm not at my music computer right now, but what you're looking at in the Sync Setup dialog is the two list sections on the bottom right half of the window. If any of the boxes in those lists are checked, uncheck them.

Uhhh, just noticed that the title said "Cubase VST"... My directions were for SX 2. I don't remember how it was done in VST, but you might want to check it. Look up MIDI Sync in Cubase's Help menu to see how it's done in your version.

Hey for giggles try setting your sample rate to 24-Bit/96Khz. My Deltas report 11ms and 6 ms respectively on 2 different systems at 16-bit/44.1Khz, but report 6ms and 2ms respectively when set to 24-bit/96Khz. I monitor externally so it isn't a major problem, but if you need to you can always run at the higher rates (You do lose track counts, and CPU overhead by the bucket-loads though).
