I imported some samples from another song but they are too loud in my mix. It does not seem the NES had a way of mixing sample volumes as I see no such options in Famistudio or Famitracker . 

Unless I missed something I am considering the option of making my own samples or tweaking them with an external program.  It looks like famitracker can convert wav to DMC but I see no way to  tweak existing DMC.

Am I missing something here ?   

Hi!

You are right to both statements, there was essentially no volume control over the DPCM channel in the NES and yes, you need to use an external tool to convert from WAV to DMC (FamiTracker and RJDMC are examples.)

• In FamiTracker, if you select a sample and click "Edit" you can tweak it again.
• In RJDMC you can simply open a DMC file and tweak it and save again.

The amount of tweaking you can do is fairly limited, RJDMC can trim, change the volume and fade in/out, that's about it!

Im not 100% sur about this, but since DMC files are reduced to 1-bit DPCM, you might be loosing quality by constantly re modifying the DMC file (kind of like re-saving a JPG image multiple times). For best quality it is probably better to find the shortest path from WAV to DMC.

Ok I will check RJDMC but it is no big deal if I need to import samples from wav.  Thanks !
