Hauptwerk with Roland 900c organ

[Zenithporsche]

Anybody tried using hauptwerk with Roland 900

I have it set up via midi out cable going to mifisport 4x4 audio/midi interface. Am finding getting some latency problems. Am using surface pro computer to run the hauptwerk and the Skinner organ

Any ideas what the problem could be.....drivers or the midi of the Roland organ

Thanks

Hard to say where your latency issue is occurring, but I'd think it highly unlikely that it would be the Roland.

Other than latency, are you experiencing any other issues like audio glitches or dropouts?

I'd start by using MIDI OX or Hauptwerk to monitor MIDI traffic. One common problem is that expression pedal, or other MIDI data, can flood Hauptwerk or the MIDI interface resulting in delays.

Hi, Mark,

Have you tried using Latency Monitor running under Hauptwerk? It's pretty good at detecting problems.

To my knowledge the Midisport 4x4 is a purely MIDI device. The latency is likely on the audio side where it is not clear what is being used for the audio output. For low latency it is important to use an external audio interface. That way Hauptwerk can use ASIO (not ASIO4All by the way) for professional low-latency audio output. Look for a USB interface as a general rule with Focusrite and Presonus being two commonly available interfaces at reasonable prices for two and four channel units.

At present I go from the midisport into the USB port on my surface pro (Microsoft) and then I have separate speakers that I run from the earphone socket of the surface pro. The main problem is buffering? Where the notes start rapidly repeating themselves but in slow motion for a period of time and then it goes back to normal ....might have the terminology wrong but that is what happens on occasiond

As mentioned above you need a USB audio interface with ASIO drivers for the best, as most computer sound chips are not designed for top line audio. (Steinberg is another brand and the entry level Behringer interfaces are also good)

As a temporary measure you can download the ASIO4All driver, which usually improves the performance of on-board sound chips, but is not really suitable for the heavy stuff.

Just run a USB cable from the organ's 'To Host' port to the Surface Pro and don't use the MIDI Sport at all. (I've had so many driver and hardware issues with them - including the stuttering symptoms you describe - that I tell my students to avoid them if possible). That's what I do and the results using Hauptwerk, Miditzer, B4, VB3 and just about anything else are just fine.

With that out of the way and the organ talking directly to the tablet/computer, any remaining issues will be down to the audio system Bill has mentioned and given the solution to. ASIO4ALL is not a universal solution, it doesn't work with my HP laptop, for example. Luckily, I have Cubase installed and that puts in a low-latency driver, so I'm down to sub 20ms latency. However, at some point, if I get serious about recording with the laptop (and I don't need to solely because the organ is only a few feet away from this PC which has an M-Audio soundcard with sub 5ms possible) then I'll get myself an audio interface like the ones Bill mentions. Quality of audio will also improve over the on board soundchip, more 'headroom' and better digital/analogue/digital converters.

Thanks Guys

Will give these a try

Andy.....where is the host port on therolsnd please.....haven’t got organ in front of me but cannot invisage it

Thanks

Just happened to have the camera and organ within touching distance!

Right most socket on the box at the left of the organ.

Thanks Andy

Got it

Hi Andy

Will get lead today...so will try later

Is this how to set it up for hauptwerk

Also would this audio interface work well

Thanks

Mark

Not sure if picture of interface was on last post.....here it is

[John Kinkennon]

The Focusrite Scarlett interfaces are excellent. I use the big brother 18i20 model on both Mac and PC for multichannel Hauptwerk.

For future reference, if anyone needs a MIDI merge device, the MOTU units are reliable with the pricier models offering additional routing options. Also the iConnectivity products are worth a look though I have no personal experience with them.

[Zenithporsche]

Am looking at getting this Focusrite Scarlett.

Have done the able as suggested by Andy

Everything working well except when putting on number of voices (stops) and then opening the swell pedal find that the sound becomes stutters....is it the computer cannot handle the polyphony....how do I get around this.....buy a bigger computer

What computer are people using and specs for something like the Skinner organ that I am using please?

Really loving the hauptwerk but have got to get it working correctly

Cheers

Places to start are more RAM, and an SSD for the Hauptwerk samples. That, plus the audio interface should have enough horsepower to handle things.

[Zenithporsche]

Hi Andy

Do you think 1TB SSD and 16GB RAM would do the trick?

Cheers and thanks to all of you for the help
