I'm trying to track down a recording bug which MIGHT be due to BT PLAYBACK going out of timing against analogue (guitar) recorded input. It can't be me surely?! To try and nail it down I need a CLICK TRACK or METRONOME recording - say 60 - 90 seconds - at a GUARANTEED 95bpm from an independent source to lay across my DAW and see which one is running out - me or 'it'. Any offers greatly appreciated. Bests Ian

Which DAW are you using, as most DAWs will have a "metronome" of sorts somewhere?
Mike.

Hi Mike Not this one. Its Cakewalk GTPro2. 2004. Lol. Until recently its been rock solid and can't understand yet which is running out of whack. I need an 'outside' source of 95bpm to try and check what's happening. Bests Ian

Just had a look at the docs and are the metronome controls the A B C buttons on end of transpport bar?

Hi Ian, If needed I can make a 95bpm click track and email it to you. I can't do that until tomorrow afternoon but let me know if you want me to do it.
best regards Roger

Bests Ian Hi Roger that would be most kind. ianplant8(at)gmail.com I really want to nail the reason why they dont still line up after a few seconds. Example - I can run a guitar track in to the BT and be on time. Im not THAT bad! But the playback progressively goes out so that by 60 secs I can be a whole quarter note equivalent early on the beat. And its not constant either - it wanders. ATM I'm resigned to note shuffling, some of which horribly obvious and Id like to get to the bottom of it. Bests ian

Might be stating the obvious, what is the latency, and are you monitoring your guitar input through the track or able to "zero" latency in your interface.
Try playing along to a midi file which should be clocked within the daw and at the 95bpm and presume 4/4 timimg?
Mike.

And its not constant either - it wanders."Hi Ian, You sure come up with interesting issues !! If this was due to latency line up then it might appear to be more noticeable as the playback went on but would be easily cured simply by altering the start time. It's also possible that the PC is under such a load that the recording is being randomly delayed at certain times? What you are describing sounds more like a tempo issue.
At some point and that might be at the start or later, one or other is running at a different tempo. Since you are using Cakewalk have you checked the various ways that CW can alter tempo ? Tempo is a bit complicated in Cakewalk
There is Project tempo and midi files will usually automatically conform with this. Additionally they can also have different tempos inserted. If you are also using audio files, these normally will not automatically conform to the Project tempo unless the track is specifically set to do this. Then the audio will be stretched or shrunk so as to conform to the project tempo. Also there are settings in deep dark recesses that use clock synchronisation and audio bit and sample rates. So, first check that the tempo for each track is the same and if they are both audio, whether one has been set to conform to the Project rate and the other not. Then start a new Project and use settings to put Cakewalk back to it's factory settings. From settings check that it has found and is using the correct audio card. Reload the tracks and see what happens. Seem to recall you had a PC with multiple sound cards all active. Is this still the case and the one this issue is on ? Good luck. George

Hi I wanted a totally independent 95bpm track to try and calibrate my DAW as it were. Put it in as Track 1 and record a tap a guitar note on each beat and see the displacement. You are right that I dd have two soundcards but I've never got the Fx to work properly even with latest drivers so it's disabled now. I THINK its a processor thing. By chance I discovered on Saturday when trying a recording that the transit bar you see when recording doesn't always 'flow' smoothly at the same rate across the screen. That seems to tie in with the wavs (BT tracks) which never go out of whack with each other with the incoming Analogue guitar signal which does. The change in transit bar movement seems to coincide with the points at which the guitar timing is wonky. I have to remember that this PC was handbuilt some 15 yrs ago with I guess the only available processors/masterboard ofvthe time. Perhaps today they'd have much more 'grunt'. I may have to live with it. Sigh. But I wonder why it is that this issue came in after years of service. Bests Ian

Hi Ian,
If your guitar input is going to the computer/DAW it’s not analogue, it’s going through a the digital converter on your audio card, computers can only process digital signals!
It seems that you have reverted back to some older sound card/drivers that have increased the latency, the best option is to install only your newest sound card (physically remove the other cards), uninstall the all previous drivers for the others and re-install the corrects drivers for that sound card again.

Ian,
This might sound a bit simplistic, but I had similar latency problems using my old HP Pavilion and there were times when speeds became slightly erratic and annoying. I was told that this symptom became noticeable because I had using our old HP LT for recording (DAW) and the music processing was sensitive to the increased workload (we used it for everything) I since acquired a LT that is solely dedicated to recording (DAW) and BT/TAB/Sound File storage and latency is consistently at 62ms.It has a Intel Core i5 7th Gen. When recording I close down everything I possibly can including internet so no unscheduled update intrusions etc).
This may be way off target to your issues though?
Good luck, Barry
