vstrattomusic Posted December 25, 2018 Share Posted December 25, 2018 Hello, I've been recording some songs, and the Helix's sample rate is default at 48000Hz, however my projects are in 41000Hz, I've run into problems after hearing ticks in my tracks, thinking I'm going to have to record it all again, but then I switched the project sample rate to 48000Hz, and they went away however, the audio files now come up as modified, I'm using Studio One 4. What should I do? Re-record 4 songs again just to be safe or is there some workaround to this? Quote Link to comment Share on other sites More sharing options...

vstrattomusic Posted December 25, 2018 Author Share Posted December 25, 2018 Ugh nevermind I'll record 4 songs again tomorrow with everything set at 44.100Hz, this album is cursed I tell you, it's the 4th time I'm going to have to do it, first it was tuning problems, then lollipop cable that made DI signal weird, now it's the sample rate. lollipop me.

vstrattomusic Posted December 25, 2018 Author Share Posted December 25, 2018 Nope, nevermind turns out Helix only outputs 48000Hz audio, the setting has no effect on USB signal, turns out I'm doing all my songs in 48000Hz now? Or maybe I should record with my Focusrite 2i4 and then Reamp through the Helix? But then the signal will be different since the Focusrite guitar signal will be a lot stronger than the Helix guitar signal. Quote Link to comment Share on other sites More sharing options...
zolko60 Posted December 25, 2018 Share Posted December 25, 2018 Helix outputs and inputs all sampling rates up to 96kHz thru USB on Win nad OSX. LT, Floor, Rack outputs all sampling rates thru AES/EBU. Quote Link to comment Share on other sites More sharing options...

Then why do all audio interfaces have an option to change sample rates in the driver options but not this one? Why do I get pops and crackles that are related to sample rate?

zolko60 Posted December 26, 2018 Share Posted December 26, 2018 It can be! I do not know anything about Studio One 4 and your operating system, but on Windows, any ASIO DAW/host I use requests sample rate and buffer size and gets it. No pops and crackles, just higher latency than expected. Quote Link to comment Share on other sites More sharing options...

No pops and crackles, just higher latency than expected. Anyway I'm going to try again today, switched all projects to 48kHz, disabled & disconnected all other audio interfaces. Usually I switch between Helix & the Focusrite, using the Focusrite for direct monitoring with XLR & mixing when I'm done with the Helix, today I'll be direct monitoring through the headphones output.

talwilkins Posted December 30, 2018 Share Posted December 30, 2018 I just read in the manual the I/O sample rate setting does not affect USB sample rate operation. It doesn't say what the USB sample ratie is though. Quote Link to comment Share on other sites More sharing options...
talwilkins Posted December 31, 2018 Share Posted December 31, 2018 Update (from the manual): Helix functions as a USB 2.0, multiple-input/output, 24-bit - 96kHz, low-latency audio interface for Windows® and Mac® computers, as well as for iPad and iPhone (with optional Apple Camera Connection Kit adapter), and is compatible with all major DAW software. NOTE: For USB audio operation on Windows® computers, it is necessary to download and install the Line 6 Helix ASIO® driver (see page 56). For Mac® computers, it is only necessary to download and install the Line 6 Mac® Core Audio driver if you desire audio sample rate operation at rates other than 48kHz (see page 56). These drivers are available from line6.com/software. There is no driver installation necessary for an Apple iPad or iPhone. This seems to imply the USB is set to 48kHz as standard and can be changed thrue the driver software. Don't ypu just love manuals? 1 Quote Link to comment Share on other sites More sharing options...

No pops and crackles, just higher latency than expected. USB sample rate is independent from Hx DSP native sample rate. It is dependendent on ASIO driver (or OSX Core Audio request when multi sampling rate driver is used). Quote Link to comment Share on other sites More sharing options...
talwilkins Posted December 31, 2018 Share Posted December 31, 2018 It seems you can only adjust the bitrate in the Apple driver, not in Windows. So 48kHz zeems to be what it is in Windwos Quote Link to comment Share on other sites More sharing options...
zolko60 Posted December 31, 2018 Share Posted December 31, 2018 No. You can use all sample rates on Windows either by changing WDM driver settings accessible from ASIO Control Panel or by DAW/HOST request. Also check the link, and follow the white rabbit. Quote Link to comment Share on other sites More sharing options...
vstrattomusic Posted December 31, 2018 Author Share Posted December 31, 2018 It can't be changed by control panel. This is Focusrite Control Panel, which I can access from the Win start menu: This is Helix Control Panel, which I can only access from the DAW: It doesn't specify any sample rate in the manual, that's wrong, there should be more info on that. It just sticks to the sample rate of the project, it's a bit confusing. Quote Link to comment Share on other sites More sharing options...
zolko60 Posted December 31, 2018 Share Posted December 31, 2018 You click Sound Control Panel. Right click Helix/Properties/Advanced and set sampling rate for WDM and ASIO driver. Albeit you don't need to touch it when you adjust (request) sampling rate and buffer size with Reaper, Ableton or Pro Tools. Quote Link to comment Share on other sites More sharing options...
vstrattomusic Posted December 31, 2018 Author Share Posted December 31, 2018 Yeah, in Studio One 4 you don't need to touch anything either but still it would have been nice to have some official clarification, I was having pops/crackles issues, which seemed to be related to sample rate so I wanted to sync the Helix > Helix Driver > DAW sample rates. Then again the Helix itself outputs 16 bit audio but then works as a 24 bit interface too doesn't it? Anyway I don't care that much about the drivers bugging out and giving me pops and crackles, what bothers me is that I don't want those pops and crackles to be recorded in my DI guitar takes that I will use for reamping later. It can be very hard to get everything in perfect timing and tuning, it makes me mad having to record the same song like 5 times. Quote Link to comment Share on other sites More sharing options...
zolko60 Posted December 31, 2018 Share Posted December 31, 2018 I can not confirm the behavior you report. I have some crackles on the 64 samples buffer at 96 and 48kHz with high CPU load, however Helix seems to be stable audio interface (with higher latency than I was expected in 2015). Maybe you run two interfaces with no sync and that induces jitter? I believe helix is 24 bit. If you are not successful at making Helix work as an interface, you can try its digital outputs to another interface. EDIT: I used to have big crackle problem and Hx Edit disconnecting after couple of minutes untill I swapped USB cable. Quote Link to comment Share on other sites More sharing options...
