while using dpcm from nes games, i noticed that the volume lowers for the triangle and noise channel. is there a way around this? i know that there is, since rushjet1's own made dpcm doesnt change the volumes, so how can i do that myself?
Open the DPCM sample in RJDMC or FamiTracker's sample editor and then tilt the end of the sample until the sample ends at 0. (You may need to ensure that this indeed happens for different initial delta positions,)
