audio thru Sonar and back to 8 Pre not crisp
I have my keyboard and drum machine running to my MOTU 8 Pre thru 1/4 inch cables, then to my laptop (an HP Pavillion with Sonar 8.5 Producer on it) and back thru a Firewire cable, then to monitor speakers.
I set up a dummy song just to play around and practice. In playing a drum machine loop for rhythm, I hear a delay on about half the keyboard notes or so that I play. It sounds very sloppy. The drum loop sounds OK.
Does anyone know what the problem might be?

Thanks. I cut the buffer from 1024 to 128 and it worked. Then, after a couple minutes of playing (without latency), huge static started going thru the whole thing until I turned off the keyboard. I reopened the dummy song again and the same thing happened, except I had to turn off the drum machine, as well, in order to stop the static.
I don't like to keep asking questions, but any ideas?

See how easy that was..  But now your getting static. This can be from a wireless network. Do you have any wireless enabled on your pc? Do you have a TI Firewire chipset in your pc? Cj

I don't think it's the wireless. I tried undoing the connection a couple of times and it didn't work. I don't know if I have a TI Firewire chipset or not. It may be that I just hooked up a Furman PL-8 C power conditioner today. I don't know, but will try bypassing it. The noise sounds like the clicks that go thru the speakers when Sonar is opening up, but repetitively. Then it will stop and I can play for a while before it happens again.

Now it sounds like you've dialed your buffer down too much. I have mine at 256, and my latency is 5.8, which (despite what others may tell you) is extremely tolerable. Randy B.

Undoing the connection isnt good enough!! If you have a wireless pci card in your pc, it should be disabled in the device manager and maybe even taken out of your pc. This can and will cause what your experiencing. If its not that, it could be an IRQ conflict http://audio-mastering-mixing.com/FAQ___Q_A.html#36 Also, can you list your pc specs Cj

I tried it at 256 and it sounded fine, but the occasional clicks with the block out of music still happened. My computer specs: HP Pavillion dv9925nr Windows Vista Home Premium 64-bit AMD Turion 64x2 processor 219 GB hard drive memory (120 GB open) 2.0 GHz 4.0 GB RAM Conexant HD Audio 32-bit color max resolution 1440x900 DVD+/-RW broadband capable Also, at times Sonar drops or loses the Conexant audio card and at other times it asks me if I want to add the MOTU connection. It either does one or the other, never both during the same session. I tried bypassing the power conditioner and it didn't work. The funny thing is I recorded 93 songs into Sonar from my old setup within the past two weeks and didn't have much of a problem, except for the dropping of the Conexant audio card occasionally.

Tried even at 512 and the same thing happens. If I put the buffer back to 1024, I don't have a problem, but the slight latency is audible.

Hi, Vajnar
I have an almost identical HP Pavilion laptop, the dv9700. 64 bit, dual AMD, 2.1 GHz, 4 gig RAM.
But I'm not using as elaborate an Audio/MIDI interface as you, I just have one stereo pair out going to my amp and then speakers. It's the Alesis iO|2.
When I'm working with hardware synths like you are, I work on the MIDI tracks to drive them in Sonar, but just let the outboard equipment play through a line mixer I use, without folding the audio back into Sonar- that's while working on a project.
Naturally I bring those tracks back in when I'm ready to print tracks, but at that point it doesn't matter what the latency is, since I've already done all the MIDI editing and at that point just need audio tracks.
What I'm not understanding is why you still have the HP audio card connected, the Conexant (which is on my macine too). You have the MOTU - that's replacing your on board card, so why is the Conexant still turned on? I have mine disabled so that I'm only dealing with my interface.
For the heck of it, when I first got this laptop, I ran a test to see what would happen trying to use the Conexant in Sonar - and it was hopeless. No settings would produce anything but broken up sound and impossible latency.

Hi, rbowser. I could see what you mean about skipping the audio routing to and from the laptop. As I wrote, the drum machine plays fine thru the 8 Pre to the laptop and back. So I think, as well, that it must partly be the synth's up to 64 voice polyphony causing the latency. I would like to find a way to play thru the laptop, though, as I would like to play thru it live and potentially record it. If necessary, I will get a new keyboard or laptop. I didn't know about disabling the Conexant sound card. I will do that, I guess, before opening Sonar.
