Vikash, in reply to your questions..........
>Is it possible to use the virtual tracks and the main track simultaneously for playback?? or just one at a time? <
Only one per track, for example 1a or 1b or 1c etc.
But you could have 1a & 2c & 3B etc if you wanted.
If you have a track on 1a and you want to also listen to 1b at the same time, you will have to move it to another channel (you can swap virtual tracks to any other channel)
>2nd :I've a problem that the vocals sound in front of the music even when i change the volume of it ... Is this a mixing problem?<
It's probably a combination of your voice, the mic you use, how far away you sing from the mic and what you do with effects.
If your voice sounds boomy, try singing a little further back from the mic. Try removing some of the low end with your EQ then add some compression & a little reverb. Trying this might help some but it's best to experiment to find a sound you like.
>3rd: I use
my korg i3 sequencer to arrange all of the music... then I take the drums, bass en backing music to three different stereo tracks on
the D1200 . And for the vocals i use a different track(track one) : Is this way of working good..or do i have to change that?? <
I do a similar thing using my PC to sequence my drum machine & keyboard. Using the Korg as the master timer, I can track the rest of my parts (vocals, acoustic guitar or whatever) and then record the midi parts on seperate tracks when I'm ready to do the mix.
This gives me more control over the effects etc of the individual midi parts and has the added advantage of letting me tweak the midi parts right up to the last moment.
This is just one way of working- there's no right or wrong. If it works for you then that's what matters.
Hope this helps.
