What is the bext way to set up Studio One for live multi-track recording using Firestudio Lightpipes? Should record as one very long song or is there a better way?

thanks

I typically record shows involving 3 or more bands performing one set each. I set up a separate song for each band.

Studio One Pro 1.5

OK, thanks. Looks like there is no problem with a 90 minute song.

One more Q: Can I chain to Lightpipes together via firewire to record 32 channels @ 24/96?

Maybe, but I have a hunch not. FW can handle in the neighborhood or 5o streams, I believe, but I think that is at 44.1/48k, and there may not be enough bandwidth at 96k. Check w/PreSonus, though, to be sure. In theory, it might work, because you can sync via word clock. The other question would be can you computer and hard drive system keep up.

for what its worth I have recorded 7.5 hours straight with s1 artist and studiolive 16 and it worked fine all in 1 song - lots of post editing required though

Yes, long stuff is no problem here, either (although I tend to like to break up my files a bit by starting and stopping recording manually during pauses once in a while).

I spoke with TS (wait time was 35 minutes).

They said FW is limited to 104 streams which explains the Universal Control published limit of 52 channels of input and output. If a Lightpipe is running at 96khz then it only has 16 i/o channels so it seems to me two of these would fall under the 52 (104) limit. The UC docs show how the multiple interfaces are "mixed" into a single interface of up to 52x52 channels. It also says any member of the Firestudio may be chained. The problem is a cannot find any examples using more than one Lightpipe at 96khz.

Google doesn't find much info either. I can buy one and sell if it doesn't work but that is a hassle.

Does anyone know of a means to record 24-32 tracks at 24/96 via ADAT to Firewire?
It seems easy to get 32 at 24/48 or 16 at 24/96.

Update!!!

I finally figured out how to make this work. The Firestudio daisy chaining instructions are a tad ambiguous as to how the 52 channel limit is reached. I specifically tried to determine if using SMUX cut the ADAT channel count in half. Well it turns out it mostly certainly does. I chained a FireStudio 26x26 last night with a FireStudio Lightpipe and starting to experiment. If you select 44.1 via UC or the Audio/MIDI utility (MacBook Pro) then the utility will list 58 in / 58 out. Selecting 96 changes this to 38/38 which is what I had hoped since the combined 40 ADAT channels (32 and 16) are now down to 20 in SMUX mode.

When Studio One loads the I/O config shows the combine channels although the names aren't correct. The device is listed as FireStudio so it must have the lower device number than the Lightpipe. Through trial and error I determined the 24 ADAT channels
were as follows.

LP 1 - 16: ADAT 11 - 24, SDIF-L, SDIF-R
FS 1 - 8: ADAT 1 - 8

No idea what is in ADAT 9 and 10.

Before I got to this wonderful solution, I crashed S1 a bunch of times. The problem is that once set up for 96 using SMUX you CANNOT allow anything to set the rate to 44.1. Doing so immediately throws an exception on an I/O thread in the device driver. I was able to do this many ways including opening a 44.1 song or changing the rate via UC or the Audio/MIDI utility. As long as youy stay at 96 to avoid crossing the 52/52 I/O limit it all works great.

But can it record? You bet!

I routed pink noise into 24 channnels on my 02RV96. I then routed each to a digital slot channel and fed to the 2 units via ADAT.
I verified each channel came up on the interface as I added them. I then recorded a minute with all 24 tracks at the same time.
The performance monitor showed the CPU never exceeded 15%. The disk never exceeded 18%.

I also recorded a few sine waves at different frequencies in the first and last several channels to verify that each interface was keeping all the channels correct. Worked as expected.

I hope this post will hang around for anyone who needs more than 16 tracks at 24/96. I can do 24 with no problem and lilkely 32 with two LP units. All of the docs show this as an unsupported chaining but they do not take into account the SMIUX at 96khz. Perhaps PreSonus will update to explain how that factors in to the max channel count.
