What dosbox version? Does it behave different with the normal core
and/or cycles=auto?
Try soundblaster or gus, depending on what you selected at the moment,
and maybe reduce the sound buffer sizes in dosbox.conf

I have dosbox 0.65

This is my config :

fullscreen=false
fulldouble=false
fullresolution=original
windowresolution=original
output=surface
autolock=true
sensitivity=100
waitonerror=true
priority=higher,normal
mapperfile=mapper.txt
usescancodes=true

language=
machine=vga
captures=capture
memsize=16

frameskip=0
aspect=false
scaler=normal2x

core=dynamic
cycles=20000
cycleup=500
cycledown=20

nosound=false
rate=22050
blocksize=2048
prebuffer=10

mpu401=intelligent
device=default
config=

sbtype=sb16
sbbase=220
irq=7
dma=1
hdma=5
mixer=true
oplmode=auto
oplrate=22050

xms=true
ems=true
umb=true

What I need to change?

I don't know what you *need* to change as it ever worked flawless for me.
But core/cycles/blocksize/prebuffer are options that can have an effect.
In fasttracker itself, the type of output (sb/gus and their parameters)
matter and different configurations might work better for you.

I have change drate=22050 to 44000 and latency go away but sound gets interputed for a time to time with short period.My fasttracker config is the same when I used it in dos, so I'm sure that it's good configured.Before I use booth Win98 and XP. XP for all and 98 for fasttracker but everytime I wanted make some music I had to reboot computer.This was really burdensome so now I have only damn XP. 😠 Please help me 😢 I have soundblaster 128

Maybe you should try Skale Tracker instead.

If Freddo's advice doesn't help:

Hope you're aware that dosbox emulates a different sound card and behaves
different speed-wise as well.
Change cycles to auto before proceeding, then be sure that ft2 is set up
with sb16 irq7 dma1 (hdma5), after that try gus (irq5 dma3 or something
like that, see dosbox.conf).

Ok now I know where problem is.

nosound=false
rate=22050
blocksize=2048
prebuffer=10

In this line when rate is 22050 sound is good but is small latency.After change to 44000 there are no latency and is better sound but encounters interputs.I have changed to gus but is worse than sb.Maybe I shuld change prebuffer or block size but I don't know what to type there.

I assume you set it to 44100 not 44000 (?)
Tried to reduce the blocksize and prebuffer as well?

I have doubled blocksize and prebuffer, now there are no interputs.Sound is good, frequency 44100 ,but I still have latency.I changed frequency, blocksize and prebuffer ,disabled 16 bits sound ,interpolation ,stereo but this don't helped.Some sugestions?

To reduce latency you have to make the buffers smaller (see the postings above).

Thanks for help, now everything works correctly! WD big beer for you!😊
