Hi all, I'm in need of some advice/help as my first time with an audio interface. Focusrite Scarlett Solo 2nd Gen. Until now I've been using a "direct" connection from my Rumble 40 to the PC's line-in playbacking and recording with Audacity. The reason of using an audio interface is to be able to sing and play bass at the same time I playback a song. I'm not in need of a home studio or something else. Just basic play/record usage. I was able to playback and record connecting all as follows but there some things I think I have to iron: * Scarlett Solo to USB - Not using the back RCA outputs yet * Mic to Solo's Mic input * Amp headphones out (which was my old line-in input) to Solo's Intrument input * Line/Inst switch to "Inst" postition * "Direct Monitor" ON. It seem to be the only way to hear sound by headphones (???) * Headphones (I always use them to not to disturb at home) to Solo's headphones out As I said before I use Audacity. It's simple and works fine for playing along and record my bass. I never cared about its config, sincerely, and I only tweaked the latency correction setting to match line-in recorded track to the "backing track" while playing them along. I have some doubts about all this, so any help is welcomed! Audio Host: Audacity shows three Audio Hosts: MME, DirectSound y Windows WASAPI. In Audacity's online docs it says it supports ASIO too but this does not show Multi-channel Recording - Audacity Manual So I left the default host "MME". It seems that, ASIO apart, WASAPI audio host is the best option due to low latency and record capabilities. I have to try it. Am I doing it right? Should I get ASIO drivers too? All? None? Another option? Input/Output: For Input Device I chose the "Focusrite Scarlett" device and for Output Device the default built-in audio device "Realtek...whatever". It worked but I'm not sure if is the best option. I've to test this more. Playback: With the above configuration I was able to sing, play bass along the backing track. So far so good! I noticed that only playing bass and singing thru the Solo interface was fine after some gain level adjustments, but when adding the backing track all sounded a bit blurry. I don't know if it's only a gain/volume adjustment issue or something wrongly configured. Recording: With the above configuration, I started recording a song I know almost all its lyrics (Somebody to love cover by Ramones) pressing shift+R (record on new track) in Audacity. I saw voice on left channel and bass on right. Fine, but... ...when I playbacked the whole thing (backing + recorded tracks) I noticed the tracks out of sync, too much indeed. I remember I tweaked this a bit for line-in recording long long time ago and works perfectly for me and bass and backing track were finely sync'ed. All said, I'd like to know if I'm using the interface correctly. I have no previous experience with them. I was thinking about connecting the Solo's out RCAs to the computer's line-in (I bought a RCA to stereo mini jack too) to "keep" my old config but I don't know if it is a good idea. Any help/ideas here? For the Audacity's recording latency issue, audio host and I/O devices configuration (Recording Preferences - Audacity Manual) is there any thing I should know or I could tweak for a latency-free (or almost free) setup? or simply a better setup? Drivers? I/O devices? Latency correction ms? Tips? Thanks a lot for your help! Have a nice day!
