Hey!

Would anyone be willing to share a famitracker instrument configuration with dpcm bass samples (or any other melodic tones), and more importantly, the pitches laid out in a working manner?

This was posted over at the 2a03 forums (probably here at some point too?)

DPCM info table

This is helpful, but I'm a little confused trying to place sharps or flats within that chart. I guess I could load a second sample with the starting pitch as C# at $0, and have it be $5 to make it A#?

Also, would it make sense having a different C and C# at $7? Since the pitch affects the speed of the sample, I take it you'd need at least 4 samples if you wanted to be able to play accidentals, as well as cover a considerable range of pitches without there being TOO huge a difference in how long a sample lasts (a longer/bigger sample for the higher pitches, shorter for the lower...)

I'm having a hard enough time getting started on figuring out how to work out some sunsoft-like bass parts, and I'm curious to see how others have worked it out.

edit: the [code][/code] function on 2a03 makes the chart look a tad nicer here, if you wanted to check that out.

Here is what i did with one of my previous tunes
when making a linear DPCM Bass.

the bass is located at Instrument 1.

note: the base note at C is actually G,
for reasons i cant remember, but thats the
way it is :P

if FTM doesnt load properly, download
the other beta at http://www.ihateui.com/FamiTracker.zip

Oh, so you just left the pitch at 15 each time and used a different sample for each key on the keyboard?

That sounds a lot easier than what I had in mind. Haha, I think I was making things difficult for myself.

These FTM:s has the bass instruments from Sunsoft games like Gremlins 2 and Dodge Danpei.
(You'll need the latest FT beta to open them)
