Can I run my guitar and mic through a Bose 2 channel speaker, both channel can independently be eq'd, it has a line out...can I run it to one track on this machine and double my instruments
@mindsofmirth3 ай бұрын
If your line out is a 1/4 inch jack (standard guitar jack) then you can plug in direct. If both channels are coming out from only one line out, then plug it into either line a or b and assign input to track 3 or 4 on the Tascam. This way it will be in stereo, which means their levels must be mixed relative to each other from your output source firstly.

When finished making a mater track, push ' rec mode' button and go back to 'multi track', then push 'menu' button and scroll down to 'import/export' and execute. It will ask what you want to export - master track or individual tracks - execute master track. then, it will ask you to name it, then execute it after naming. It will take a while to export. When finished, shut off unit and hook up usb cable to Tascam and computer. Turn unit on and locate usb connected device on computer and click on the wave file. Here is everything on your Tascam, so look for the name that you created for this export and then copy and paste it to anywhere in your computer. I hope this helps.

Most electric drums have 1/4" outputs, so you should have no trouble jacking into the inputs on your Tascam. Drums have more attack gain, so watch your meters and overload lights and adjust input settings accordingly.

Hi, Jeffrey. Thanks for this helpful video. The DP-006 manual says that the unit can be connected to a computer with Windows or Mac operating systems. My computer has Ubuntu. Do I need to upgrade? If I attempt exporting tracks from my Tascam to my computer, am I in any risk of losing the tracks?
@mindsofmirth2 жыл бұрын
If Ubuntu can run WAV files, then I think that it should work. When exporting master tracks, you won't lose the original file - just copy and paste file to your computer after the devices are connected. It's always good to lock any files in your Tascam from accidental alterations if you want to save them for long periods.

Great vid I am a complete novice you mentioned in vid that it's best to set track type for 3 and 4 to mono can you explain why
@mindsofmirth2 жыл бұрын
Generally speaking, if you are multi-tracking, then recording in mono allows you to isolate each track fully into either left or right ear, or a percentage mix within each ear (panning). For example, you could do a 50/50 mix, or a 30/70 etc. with mono. When recording in stereo, then you can never fully separate the sound and there will be a mix in both ears that can't be isolated, in which case the panning knobs become balance knobs (which means that you're increasing the volume of that already recorded mix in one ear or the other, but not separating the recorded sound). Balance is really only important to the final listener. For example,' if you're in a big room but you're sitting closer to the right speaker, then you would want to change the balance more to the right - which doesn't change the overall mix of all of the instruments. I only record in stereo when I'm recording a live performance with a stereo mic. Then, the final product is how a live listener would here it (at the position of the microphone). I give an example of this on my channel with the 'RAIN' song. Good luck!

You can't change name in 'create' without just creating a new song. You must 'load' a song from the song menu, then enter 'name edit'. p.s. you cannot name two different songs the same name. Also, when loading or creating a different song, then the one you were working on will be stored under the name you originally gave it - unless you name edit it.
