The MV's Audio Tracks are not midi midi dependent in any instance and they can be recorded live in a linear recording fashion in time with the song.
The MPC Cont.Sample tracks cannot do this.
Audio quality? The MV doesn't sound better than an MPC.
Actually it does in more critical situations when recording llive or when mated with decent Mic pres- and I'm not saying this for the sake of disagreeing. The MVs uses the same TI/Burr Brown converters as the VS-2480. The processing is 16/20/16 opposed 16/16/16 on the MPC's by Numark.
Even when saving to 24bit with the new MPCs, there only 16bits in the file because it is "Saved As" (repackaged) not "Converted to" a 24bit format unlike the 4000 which is true 24bit. This means that there is dynamic headroom available in the MV during proceesing that is not present with the MPC. The signal's integrity will not be lost when using the MVs MTK.
Going back to sound sound quality, converters are key as you know. The MV's converters are of same PCM 4200 series chipset as those currently used by Apogee. This is listed and confirmed in both the MV and VS service Manuals.
The NSC/Numark chipsets are amongst the cheapest on the market and not used by anyone in critical audio applications. The NSC's primary market is and always been low cost home ,portable and car audio processors.
Laterabbit- if you're concerned about the tracking vocal in the MV there is a separate Vocal suite in the MFX. The vocal multi stack as follows:
Noise supressor
Limiter -De-esser
Enhancer
Para EQ
Pitch shifter
delay
chorus
I like to use the templates and suggestion from the guys at Prosoundweb. You can punch in there numbers and come up with some good starting points. Not that you need them. Like anything esle the MV's MTK is only as good as the ears behind it.
