3541 bug reports

TravelRec.

This is not true for me, ASIO works flawlessly with 3541, with 10ms on my machines. Not really as fast as possible, but stable. With 3534f, 5ms were possible.

When right clicking a file or folder, the HDD access spike will cause fb2k to stop playback, untill you are no longer using the file. also when playing back MIDI every 64th note will squeek

Russ

I have no such problems (WinXP). Maybe it is something specific to your system. Try disabling anti-virus software, etc, and see if it makes a difference (certain scan options can have a big impact on system performance, etc).

I haven't noticed any squeaking... Do you mean 1/64 notes, or the 64th note out of every 64 notes? If it is 1/64 notes, at what BPM setting? Maybe it is application specific, what are you using for MIDI playback?

... (from below)
Yes, but not everyone has a dedicated music workstation

TravelRec.

I also have not such a problem - are you using some USB- i/o devices? Please check also your task manager for running processes/services. There should not run more than ~20 at the same time. Russ: A music workstation *should* not have any anti-virus software running at all...

Lemonzest

The midi Squeak is every 64th note played it sqweaks, and i think the skipping problem is PCI latency related, but i have it set to 32. no anti virus or programs that scan files on opening. the midi playback programs are just old games such as ZDoom, and games in dosbos that use General Midi. so playback is standard.

TravelRec.

Which device you are using for MIDI playback? kXSynth1 or 2 with soundfont "xy" or Windows built in software synth?

Lemonzest

kXSynth1 with Creatives 8MB soundfount

TravelRec.

Okay - I will cross-check this.

EDIT: Tested MIDI with the kX-Synth1 and Creative 8MB SoundFont, on 3 different computers with different cards and with modified 3541 kX.sys - no problems so far - crystal clear sound.

Russ

Connect a peak plugin to FxBus 2/3 to verify that it is actually using the kX Synth(s).

i.e.
You mentioned old DOS games, which often used FM Synthesis, etc... I am not sure what ZDoom or dosbos uses, but it may be just doing some kind of emulation.

tjbw

how do I save settings in 3541?

Lemonzest

Russ they are using the Kx Synths, i can track the songs in the Analyser window.

Eugene Gavrilov

hm...
can you try to reset voice engine between 64 notes?
that is, open any sequencer, playback 70 notes - watch the kX Mixer's 'voice analyzer' - check if distortion happens during wraparound of the hardware voices

after that, playback, say, 35 notes, stop any audio/midi playback, reset voice engine (use kxctrl or kX Mixer -> console -- I don't remember the exact option, search the forum or run kxctrl without parameters - it will tell you how to reset hardware voices), after that, playback 35 notes - check if there was a problem with them

i wont be able to run that test as i dont have a sequencer, i'm just a gamer, not a music creation person, just reporting my findings.

Russ

You do not necessarily need a sequencer. Any program that can play MIDI should work (i.e. Windows Media Player), and MIDI files can be found easily enough on the internet, if you do not already have some on your hard drive.

Russ, i have just been playing a midi through media player classic, and each time i ran rv (reset voices) from the console, less and less channels were becoming available, after a few resets only half the analyser screen was showing activity!. strange, had to reboot for the midi to use all available voices again.

also, if i play a plain midi, no squeak (or i cant hear) if a game plays a midi and has a few direct sound channels open, it will squeak. maybe the midi tries to use the all ready allocated channel?

Russ

Actually it was Eugene that asked about that.

In any case, I am not sure how it is supposed to act after resetting hardware voices, but I get similar behavior.

i.e.

Before resetting:
All voices seem to be allocated for use, so each note moves to next (unused) successive voice/bar in the analyzer window (i.e. from start to end, and then wraps back to start, etc).

After resetting:
Voices seem to only be allocated as needed, and only voices that have been allocated are used (so if only 4 voices were allocated, it would go from the beginning to the 4th bar, and then wrap back to the beginning). There may be some note dropouts, etc until enough voices are allocated for whatever is playing.

Playing a MIDI file that needs all 64 voices simultaneously will (eventually) allocate all the voices again, such that it behaves as it did before the reset (so a reboot is not necessarily needed).

In any case, the test procedure that Eugene described makes me think that this is normal behavior (i.e. if it was the wrap-around that was causing the squeak, it would occur in a different place after resetting (i.e. maybe every 30th note instead of 64th, etc (whatever the wrap-around point was))... I am guessing this is what Eugene was testing).

Lemonzest

After resetting those voices will never be allocated again, even playing 2-3 midi's at the same time, so the reboot is required.

Anything using DirectSound3D or OpenAL Generic Hardware (same path i think) will cause static/crackle

hello,

thanks for the new version.

I've just tested Direct3D with World of Warcraft. Its sounds Ok. No clicks/pops for now.

48khz modes in ASIO don't work for me since 3538 L or M revision. if i switch to 44khz its playing.
I beg you, please fix this

before I was using virtual5.1 plug-in to combine all direct3d sound that comes out of FXBus 4-5-6-7-8-9 to 2 channel suitable for my headphones. but now when main should be wave 4/5 i cannot do this because if i listen to mp3 later it goes thru that virtual5.1 plug-in which is not ok for playing music. Is all that fixable somehow?


my config is:
ct4830
windows 2008
p4 630
intel 925 chipset
geforce video card.

Lemonzest

WoW uses FMODeX which defaults to DirectSound2D so does not show a problem. a game has to use the 3D version of DirectSound

Maddogg6

I personally dont think its an *easy* fix - I notice, via a A/B compare - raw stereo vs Stereo with Virtual 5.1 - that the V5.1 plugin changes the front stereo separation (seems mostly on the mids get mixed to mono), and is likely something in the V5.1 dane code thats causing this.
(edit: I also notice when V5.1 is bypassed - it only outputs right channel only - bug? seems like one?? /edit)
Me - I load/save DSP configs to work around such idiosyncrasies.

Or simply - use Wave 0/1 for MP3s and rout FXBuss 0/1 to mix with V5.1 pluins output... ?? any reason that wont work in your case?

Russ

You are talking about ASIO with Traktor (only), right?

Lemonzest

On testing UT99 which i think uses DirectSound3D it was fine, so i think its something in the wrap_oal.dll that comes with the OpenAL installer. no trouble here.

imperia

before the sounds from Wow was coming from FXbus 0/1 plus the 3D was playing simultaneously from FXbus 4/5 6/7 8/9.

I am sure 3D sound was coming out of FXbus 5-9. Sounds from my attacks/error messages were coming from FXbus 0/1 and ambient/environmental sounds were coming out of FXbus 5-9.

so i was using virtual5.1 to convert 5.1 to headphones.

imperia

that was my setup before:

that's now:
http://imperia.kicks-ass.net/KX/dsp_3541.jpg

i ignored 5.1convertor now because all sound now is coming out from FXbus 4/5 because 0/1 clicks/crackles. and when i listen to winamp the sound should not be routed thru it.
