Can anyone please advise? I have my Tyros 2 MIDI-linked to Sonar X1 Producer via USB. There is definitely a connection, I can choose different sounds and then play them using the Tyros. Trouble is, there is a short, but crucial, delay between me playing a note and hearing it. It seems to register immediately on the volume gauge in X1, but doesn't sound until a second later. I have tried all the settings I can think of to put this right, but nothing makes any difference of any kind. Your advice would be hugely appreciated.
 

The problem is most probably latency - the amount of time it takes for the software and PC to process the MIDI, create the sound and send it out to the audio interface. The latency can be adjusted either in Sonar's preferences or in the software provided by the audio interface manufacturer. There may be a need to tweak the PC/Windows to optimise it as well.
 
It would be very helpful to know what your audio interface (or if you're using the PC's built-in sound card) is and whether it has ASIO drivers (and if you are using them). Without knowing that it's difficult to suggest where to start.

The USB lead from the Tyros is connected to a USB port on the PC. Don't think I can put it through my Edirol UA4FX external sound card. So it looks like (Control Panel - Sound - Playback) that I'll be using NVidia High Definition Audio. Is that likely to be right (this is fairly new to me)? But I can find no access to ASIO drivers, or anything else come to that. I have looked within Sonar and tried some tweaking, but it has no effect, positive or negative.

Hi. Do you have the latest drivers and firmware for your Tyros2?
If not / not sure, check http://download.yamaha.com/search/product/?site=europe.yamaha.com&language=en&category_id1=16277&category_id2=16084&category_id3=&product_id=107861
Best of luck.

And I would use your Edirol for the Tyros (playback and recording).

It definitely sounds like latency.  Post your specs and ASIO settings for your Eridol.  I am sure that someone here can get you sorted out.

Hi everyone. It sure sounds like latency. But I don't (currently) have a MIDI lead, so am using a USB connection, Tyros to PC. Bearing this in mind, exactly which settings should I be looking at and posting? By the way, thank you for your kindness.

 
Do you have monitors hooked up to your Edirol UA4FX to output your audio to ?  I suggest you keep your keyboard on usb direct in, then output your audio through your Edirol to your monitors.  You'll have to select the Edirol in your Preferences in Sonar.
 

The problem isn't the USB cable from the Tyros. I'm not familiar with that synth, but a quick look at a downloaded manual seems to indicate the USB only handles MIDI and the editing/librarian software, not audio.

If that's correct, then from Sonar's point of view the only thing coming and going via USB is MIDI.

Latency is to do with audio processing, much more than MIDI.

As you have the Edirol interface you do not need to use the NVidia hdmi driver. That is there so your graphics card can send audio down an HDMI cable to your monitor in case it has built in speakers. Some people have found that disabling HDMI audio drivers in Control Panel/Device Manager can go a long way towards curing apparently insoluble latency problems.

Sonar does not use the audio drivers specified in the Windows sound settings. It uses whatever audio interface it is told to use in Sonar's own preferences.

Are you using the sounds in the Tyros itself or using it as a MIDI controller to play other software synths?

If you are using the Tyros as a synth, how are you hearing the audio from the Tyros? How exactly are the audio outputs connected, and connected to what? Are you using the "audio track echo" function in Sonar to hear it? If so, then the delay is caused by how long it is taking Sonar and the PC to receive the audio then process it and send it back out.

To lower that delay you need to first check Sonar is using the Edirol. If ASIO drivers are available they will show up as an option. Download the latest drivers from Roland and install them first.
