i was trying to make c64 drums on 5b, which works perfectly. however, whenever i start the song up, the noise and a few notes of the pulse are muted for some reason. i've attached an ftm below to show you what i mean

Are you using the latest beta?

NSFplug seems to have issues when playing a N163 PCM Stream at 67hz
Attached FTM (works in both 0CC-FT and the Latest Beta) and NSF

I am able to reproduce the same issue in 0CC-FamiTracker because the tempo value is set to 255, which is much higher than what the engine speed allows (167.5 BPM); the internal tempo counter underflows after the subtraction in ft_skip_row_update, causing some rows to become much longer. Because the remainder of the tempo division has been taken care of since 0.4.6, that routine should make sure var_Tempo_Accum never underflows:

Code: Select all

`ft_skip_row_update:
; Speed division
; ...
lda var_Tempo_Accum + 1
sbc var_Tempo_Count + 1
bcs :+
lda #$00
sta var_Tempo_Accum
: sta var_Tempo_Accum + 1
`
If this check is absent, for the official build the only way to get around this in exported NSFs would be to set the engine speed to default (60 Hz) first, and the tempo to 150, then export the NSF, and finally edit the refresh rate at $006E as necessary to minimize the phase shift through the N163 waves. Although the 0.5.0 beta allows directly setting that refresh rate, most values do not admit a straightforward way to specify the number of ticks per row, rendering them unstable for use with N163 PCM.

Volume in Digging in the past on the 5B is totally broken. It wasn't like that in the last beta I tested it in, which is beta 2.
I also noticed that 5B note table or whatever it's called has been modified slightly (which I'm really happy about, no need for P7F on high-pitched notes anymore, yay!), so I'm going to have to edit this song accordingly later when the volume glitch has been fixed.
Edit: This glitch has for some reason stopped happening. I have no idea how or why, but whatever.
Edit 2: I'm dumb. I'm just completely idiotic and stupid. I think with my feet. I had sunsoft 5B at +6 dB in the mixer.

Hi! I'm not really active here anymore but I still make music. Nowadays I mostly make dubstep with emphasis on good melodies and chord progressions.

The note displays next to the registers are incorrect when PAL is enabled; for example, C-3 gives "281.77 Hz C#4 +28".

I am not entirely sure if that's a bug too but, the 5B Squares are "pitched down" a few cents.
The Attached module and it's source NSF sound somewhat different, the FTM was pure boredom but since the latest Beta it sounds pitched down than normal.
I don't know if that was changed to fix the 2A03 + 5B issue (something with the n163 interferring somewhere).

That nsf (which is mine) was not made in Famitracker but made in ppMCK, which uses a different tuning table from Famitracker.

This is mentioned at the change log in the OP:

> - Fixed YM2149 period table being off by one.

This in turn is due to the fact that 2A03 and 5B share a similar frequency generator:

Code: Select all

`2A03: Frequency = Clock / (16 * (Period + 1))
5B: Frequency = Clock / (2 * 16 * Period)`
The previous versions had the inaccurate behaviour where the 5B and the 2A03 use the same period table, so the same value results in a higher frequency for 5B than one would expect. For the fixed behaviour the 5B will be exactly an octave lower than the 2A03 when the same note is inputted.
