Hi Jan

Jan Loosman wrote:May be we are to much a perfectionist. I think as you did, only lifting the bass to get some more pressure (buttkick?) in the low end, wil do for me for now.
As you mentioned Kampen bennefited the most of the Arc correction. I think sample sets with long reverb wil benefit the most, because sets with long reverb are already lacking some detail and if you also lose more detail because of a muddy low end it wil easily become annoying.


You're right on both points. I even didn't try to compare with the Silbermann SACD as planned, simply because I was happy with the result I got.

By the way, are you the owner of the Johannus Rembrandt 395 which is posted on the first page of pcorgan? It's a beautiful setup, the poster behind the console makes it quite impressive! 8)

It's really nice, especially with the light effects! 8)

Too bad your screen is blocking the stop pistons on the right side though... Unless you select them all from your screen now.

I've been working for the past two days with the following target curve -

I think I'll keep it this way for the time being. Maybe some fine tuning's still ahead, but the general shape is already there.

Hi Pat

I only use the touchscreen and no longer the Johannus Stops so thats no problem.
I use about the same curve as you do and i also use the combined left right correction now.
It sounds so transparant and natural this way.
In my case al my sample sets improve with Arc as in your case some benefit no as much as others.

Thanks for reminding the L+R correction. I was so much focusing on the target curve improvement I completely forgot about this point. I shall try it by tonight - unfortunately, I live in an apartment and I can't afford to play at any time!

As far as I am concerned, the point might not be fully linked to ARC 2 by the way.

My Hauptwerk computer is a 16-GB Mac Mini. Under Hauptwerk 4.0, I can dedicate only 9.8 GB of the RAM to organ playing - Mac's OS X limitation of 2/3. Brett stated earlier in the upcoming 4.1 version, advantage would be taken of the higher possible allocation of RAM made available by newest Mountain Lion OSX 10.8 to expand the addressable RAM to 80% - 13 GB in my case.

It might help me to load Saint-Maximin, the main acoustic issue I'm currently facing, in the optimal resolution of 24 bits - today in 20 only. I have already seen the noticeable difference for another Sonus Paradisi sample set, Saint-Michel-en-Thiérache. Under my previous Mini I could load it at 20 bits, I can now do it at 24 bits. There's a world between the two configurations.

Interestingly - but we start to be far from our subject - sample set's audio rendering quality seems to vary significantly or not, according to which sample set editor is considered. Milan Audio (Kampen) sounds quite natural although still in 16 bits (I'm expecting to be able to load it in 20 bits when Hauptwerk 4.1 is released). Sonus Paradisi (Saint-Michel-de-Thiérache, Saint-Maximin, Caen) appears to be much more dependent to the selected resolution.

At the end of the day, ARC 2 cannot make any miracle - if the source is not optimal, the correction cannot make the organ sound perfectly. As usual in audio, the weakest point triggers the overall quality.

Forgive me if I've missed this, but is ARC-2 / Reaper/ suitable and usable for my Focusrite Saffire 8 ch (4L-4R +Sub) set up?
I'm very intrigued by this possibility as headphone quality is so much better than my speakers.
Thanks,
Doug

Hi Doug,

I think it should be the case as actually ARC 2 is connecting itself to the available outputs on your computer.

Just to be sure, you might give them a ring ( http://www.ikmultimedia.com/contact-us/ ) or drop an email ( http://www.ikmultimedia.com/contact-support/mi/ ).

Hello Doug

I use Arc in my front and Arc in my rear channels. So i use 2 instances of Arc together. So i think if you use it in your system you can try 4 different measurments four the front and use it or make the measurment with al the 4stereo channels together and use the same measurments. If you make the measurments connect your sub also because you wil get a perfect integration with your sub because every frequency doubling with your sub is measured and corrected with the applied filtering.

Hello Jan,

I have tried the L+R correction, which surprisingly was giving no result on my setup. I've tried it on several organs (Arlesheim, Kampen, Saint-Maximin) with the same result.

Anyways, I shall not complain about it - the result was already magnificent, I was just wondering what else could be done...

Hello Pat

My speakers are situated just in front of me, an other setup then yours. I can hear a difference between the 2settings as for now i preffer the combined correction, it sounds a bit more spacious, and with a little more body, but the differences are not that big. There is a update for Arc with improved LR correction. Before the update i did't use it but after the update it makes more difference.

Hi Jan,

Fully agree, the loudspeakers position may influence the result. In my case they are 7 meters behind me and only 3.5 meters apart from each other. We are far from the ideal triangle often described on audio forums!

Actually the spacialisation effect is done through the room acoustics and the reverb on the sample sets more than through the loudspeakers positioning - it's quite impressive to see how ample the sound is despite those distances.

This might explain why the correction L+R is not efficient for me!

Hi Jan,
I am utilizing four stereo pairs of Behringer B2031A's, with Bidule as VST "32" host, and Audio Breeze 32 for reverb.
The Computer is a Win Vista pro-64 machine, with "8 Gigs" of ram.
My most utilized sample set is The Paramount 3/32 VTPO loaded with no loss compression.
Since I am using four stereo channels, plus a Sub channel, and a sixth pair for a Headphone mix, each with their own reverb's, "would I be able to utilize ARC effectively without overloading my machine" and How ?

Hello Mel

I have no experience with such setups so i can't answer your question. But in Pat's answer you can read that it's not so much extra strain on the system. But again i don' know for sure.

Hi all,

Difficult for me to say, as I have configured my setup in stereo under a Mac configuration.

Sorry... :oops:
