  • Exporting wav tracks in-place for DAW?

    Hello, I am new to the bluebox (while not completely new to mixers nor to multitrack recorders). First things first: This little thing is amazing! So much bigger on the inside, The Doctor would say.

    Now for my question:

    My usual workflow is to record several tracks on an hardware multitrack recorder, transfer the recorded files to the computer and do the final mix in Logic Pro. This works with my Tascam DP24 quite well.

    However, the bluebox wav assets appear after import in Logic not “where they were”. Instead, they all start at t=0. (Or, well, wherever I actually drop them to be exact.) This is, of course, especially true if I just records some chunks every now and then in the track.

    Please take a look at the illustration attached. It shows the situation on the Bluebox vs. in the DAW in a simplified way.
    Timeline placement  bluebox vs. Logic

    Is there a way to place the wav files in the DAW timeline properly? I mean of course, other than drag and drop au hazard

    FYI: Bluebox firmware 1.1; Mac OS with the latest Logic Pro.

    t.i.a.!

    best regards
    Alex

    OK, seems not so important for the most of us… so I am curious how do you folks manage this. Any hints?

    In the meantime, I have found out that in the file "assets.xml", which sits inside every project folder, start and end time are saved in the code like this:

    Code:
    params trackid="4" trackstarttm="550979" trackendtm="594103"
    If a recorded asset starts at time null, it reads, of course,
    Code:
    trackstarttm="0"
    instead.

    So all I need for now is the unit the "trackstarttm" is measured which. What is it? For obvious reasons, it isn't seconds. So what does the number, in this case, "550979" mean?

    regards, Alex

      I don't have an answer but I have a way to find the answer:
      Create a 60 bpm project. Record something starting at 0. Recording something else starting at a specific beat. If you check the numbers you found in the assets.xml file, you should be able to figure it out from there given that each beat will last 1 second so starting on the first beat of the 2nd measure would be the 4 second point of the track.

        Thank you for your hint. It's getting nerdy, err interesting

        I have tried your solution. Math has never been mine, though, so I am afraid to be just as wise as before. :-0 The 2nd "track" is starting at 4.1, which are exactly 12 second in this case. After doing the math, the result was not 42, but 960. Makes (1 Beat == 240 n), while n=blueboxsecretunit. Granted the recording was made at 60 bpm 4/4, which is not always the case.

        As I said, mathematics was never my forte, so I am a little bit stuck from this point on. I tried to transfer this template to other tracks – with no success. If you have any further hints or a vital clue about what I'm doing wrong, you're very welcome – thank you i.a.!

          That leaves you with a few options. 1/320th of a second, 1/320 of a beat, or 150 samples (which is essentially the same as the 1/320s). Try again at a different tempo and you should have your answer.

        It would be easier if the Bluebox had an export function that would export all tracks with the necessary blank sections so that all tracks could be dropped straight into a Daw at 0 & line up.

          Couldn't you just rename the file after it was recorded with the beat location you started from? ex. "SynthLead 20.1.wav"

            Certainly I could. But what is it supposed to do?

            curious greetings, aljen

              Nulling out the .wav to line up at 0 for every recording would make for potentially much larger projects. If 1010 could add some sort of auto-naming suffix to the file pertaining to the punch-in, that would work. I just tested it out by renaming the file, it doesn't take much time to do and totally works. I had to use an "x" rather than a period to denote my bars/beats start point but otherwise, pretty painless.

              Having the numbers in the .xml equal milliseconds or samples would be much more useful.

                I guess that depends on your definition of 'much more useful'. Storage is cheap; for me, it would be much more useful to be able to take files & drop them straight into a DAW rather than having to scan XML & manually lining up each file. I'm also not sure that blanks in wav files increase the size very much at all. If this was an issue then this could be encapsulated in an export function with the full length files being created when required rather than being stored this way.

                virtualpt, not arguing your point, but silence in uncompressed pcm wav files takes up just as much space as nonsilence. Either way Aljenimago had the right idea, he just chose a value that worked out too neatly for both of the strongest possibilities. A more awkward bpm would have given a more indicative result, it being less likely that 1/beats and 1/samples would both work out to nice round numbers. My bet is that each unit=150 samples.

                They could make it an option. Those who care about the space would set it as it is now and those who need to align the tracks easily would choose the new option.

              Well I mean it would be much more useful in that we currently don't know what the numbers in the XML mean. If they were samples you could at least use that to line your tracks up in your DAW.

              RE: spontaneously hitting recording and wanting everything in place in a DAW sounds like you ought to just use a DAW.

                I agree, there should be at least an option / mode to fill with blank at least whatever precedes.

              DAW and spontaneous? I guess you are kidding me. DAW is the contradiction of spontaneous for me.

              As you said, we currently still don't know what the numbers in the XML mean. Does 1010music always keep so much secrecy?

                Oh man, is that how punch-in recording works in the new firmware? I though it would be ore like OP-1.
