Whats the perfect way to use the Montage thru a PC without having lag issue or notes getting stuck and playing forever? is there a way to connect the keyboard to an Audio Interface and not having this problem?

The perfect way to connect the MONTAGE to a PC is to connect it directly with a USB cable... and use the 32-in/6-out built-in Audio Interface. This way you do not have to deal with external gear and you get the advantage of 32 bus outputs from the MONTAGE!

You would download and install the "Yamaha Steinberg USB Driver" for Windows. No external device is required to receive audio and MIDI from a MONTAGE - just this driver and the USB connection. The MONTAGE then connects to your Monitor speakers. That is the "perfect way". no lag issues, or notes getting stuck ...

If you do not want to use the MONTAGE as your audio interface, then you must connect the analog Left/Right OUTPUTS of the MONTAGE to that audio interface using standard 1/4" signal cables, and use the recommended driver for the audio interface you are using. When you are using an external device as your audio interface, the MONTAGE sends audio through the analog OUTPUTS. No AUDIO goes through the USB OUTPUTS, in this configuration.

You should contact Native Instruments about how to get the Kontrol S8 (sound card) to work on Windows. Any issues you are having are related to your current configuration for audio would be solved through them (as best as we can tell from the info you have provided).

That said, the "stuck notes" symptom sounds suspiciously like a MIDI issue, as audio does not typical have issues (with hanging notes). So once again we will stress, you need to download and install the "Yamaha Steinberg USB Driver" for Windows, as it handles both MIDI and/or AUDIO for the MONTAGE, even if you only decide to use one or the other - or both. You need that driver.

Hi,

Not sure if this is anything to do with your problem, but I have had problems on computers when you plug a USB2 device into a USB3 port, despite the claim of full backwards compatibility.

For example, my MOTU MIDIEXPRESS 128 is absolutely rock solid in a USB2 port, but you get hanging notes all the time if it is plugged into a USB3 port. Plug it back into a USB2 port and all is fine.

My NORD G2 Engine will not be recognised if it is in a USB3 port, and I have also seen device drivers on Focusrite interfaces not being properly released by audio applications if it is plugged in a USB3 port (presumably because a driver is stalling during a close operation

Just a thought, and something to check.

Another thought is whether or not it is a bus powering issue. Are you devices powered by other means? If not, maybe the current drawn on a USB port is marginally on the limits, which may also be influenced by cable length. I have seen that on a GeChic Touch Monitor. It works fine all the time on a short USB cable for the Touch HMI also powering the monitor. On a longer cable it is marginal, on a very long cable the monitor will not turn on and I have to power it via an external PSU. Plug it into a 2A USB port on the computer and it is fine regardless of cable length.

Yet another thought is are you power saving settings on the computer such that the USB port is being put into hibernate mode.

Brad, the author of Cantabile (live MIDI/VST host) has an excellent generic PC tuning guide called "Glitch Free Audio" which is well worth checking out.
