I have tried nearly all 3538 releases (except j & l, i believe), and they ALL just make a scratchy noise when i play it in Vienna 2.3. I think 3537 also has problems playing it in Vienna, too. It's suppose to sound like a high sine/triangle bell tone. That's how i hear with CL drivers or in Viena. Any idea what's wrong? Unfortunately, the forum won't let me upload it, since it's bigger than 1 byte. Guess i'll have to e-mail or PM it to the project devs....

I think kX handles interpolating a sample pitch differently than CL - as I found that using a single wave sample that is like C0 - and trying to play a C4 - its heavily distorted - I found one that works called vintage synths - and it has many of the same single wave samples but sampled higher and interpolated pitch is less damaging to the patch...

I heard about this a long time ago.... so I think its been reported...

A work around is yo use SFz - it is a VST(i) and should play those patches correctly, unfortunately, editing the SF2 file will have to be done blindly (or deafened) so to speak... erm, literally, ermmm what ever.. vienna wont use a VST(i) to audition patches.
So SynthFont/Viena might be more appropriate to it (I think thats possible with viena - I never tried it)

I'm pretty sure my problem is NOT what you described. If only i could upload the file here. I mean, it's just 526 bytes(4 KB). Why doesn't the forum allow> 1 byte files. 1 byte is not even a blinking cursor, c'mon it's 2008 already! I uploaded the file here: RapidShare: 1-Click Webhosting so someone can hear it.

Perhaps a sample in MP3 for of what it is supposed to sound like (recorded with CL drivers)

Somethings I can see... (not sure if its *the* problem)
1) There exists a single sample at the beginning that is high, then 3-4 samples at 0 *then* a sine wave. and will cause a 'pop' or a glitch sounding short bass drum ...

2) 20 samples in length - (also, its not loop enabled), so, very low keys sound like a bass drum - high keys it sounds like a sharp tick sound - which tells me it was sampled at a very low root key, and all pitch shifting interpolation is like +5 octaves to middle C4 (C0 to C4 = 5 octaves).

I am pretty sure it is.

Play keys at lowest octave - at that range it sounds like the sample waveform looks to me. But, an mp3 of how it is supposed to sound - with notations of what note octave is played in the MP3 will be much easier for others to understand what you are talking about.

1. Maybe try Settings / Driver compatibility / Interpolate SRC
I stumbled upon this here: Soundfont Pitching
2. The file is broken. Shows as empty everywhere but in the single-n Viena SynthFont home page.

Unfortunately, i can't do that right now, but you can hear how it should sound in VIENA with Kx drivers.

I don't understand you here. What does "3-4 samples at 0 mean"? Are you talking about harmonics? Why doesn't VIENA(with Kx drivers, too...) have a problem playing it?

So, Kx drivers can't play short(20) sample length samples in Vienna 2.3? The sample is called "E 6" doesn't that mean it was sampled at that note?

That does nothing.

What do mean by "single-n"?

I think Maddogg6 made a good point about the fact that it is not enabled for looping. The sample is only like 33 samples long = @0.0006875 seconds of audio (without any looping).

Try the following:
Load the SF2 in Vienna. Choose "Loop..." from the context menu for "X 1 E6" (in the Instrument Pool). Check the box that says "Enabling looping for this sample" and under Loop Settings, set Local Loop End = 36 (click the down arrow once (manual entry does not seem to take)), Local Loop Start = 4 and then click Close.

Now see what it sounds like...

BTW: The file sounds basically the same to me in Viena and Vienna (unmodified). Also note that the loop settings in Vienna seem a little screwy to me (although I do not do much SF2 editing so maybe it is just me, or maybe it has something to do with kX, I do not know).

Maddogg6

yeah, 33 is reported, but counting the actual used samples - is ~20 (edit: and is reported in vienna 'local sample end : 20')

If you exapnd the loop editor - normally I can use the spinners to edit loop points - the file the OP posted seems corrupt - or at least - its not Vienna 2.3 friendly... ?? maybe edits in Viena screws up the SF2 file some how??

Russ

Yeah, I was just giving a time value based on a 48 kHz sample rate (20 samples at 29 kHz is 33 samples at 48 kHz). The main point was that it is very short (as you pointed out), even shorter than the (what appears to be the minimum (0.001 seconds) in Vienna) attack time.

By 'single-n' (sorry for being so down-to-the-point, I was busy) I meant the app from the link I had given: Synthfont Viena and not Creative Vienna. There is only one 'n' in its name ! It's supposedly named after some Scandinavian land The SF2 file didn't show any instruments in the other programs I normally use. Very strange, certainly. Particularly considering that it works in Creative Vienna for you, Maddogg6 and Russ.

The option I had suggested does help with the square wave test case from the thread which I linked. I guess some similarity of this and the other problem is 'shallow', as is my current understanding of what are you talking about guys Cheers!

Russ

The SF2 file does not contain any presets, which is probably what your other programs are looking for.

octave

Yes, the lack of presets explans the "emptiness" of the Soundfont in all the players. However, in Creative Vienna 2.40.60, after I open this Soundfont, I don't see anything appearing anywhere. Probably, I don't know what to look for. What should I click in there?

Maddogg6

Creative Vienna changed the way presets are described visually - Veinna 2.3 - showed it a little more how the SF2 file is, or can be, actually made - where a single sample is assigned to an instrument - these instruments can be layers or key/velocity splits... Vienna 2.4 - with no actual preset completely defined - obviously isn't showing much - and I dont see anyway to have it show what used to be what I called the 'instrument' pool in Vienna 2.3.
In Vienna 2.3 has an expanding list of all instruments, then one for all the presets (aka patches) - so, I can see that only an instrument is assigned in the OP's SF2 file - but no patch is assigned to use that instrument as a key or velocity range.

Russ

I have version 2.3 as well... I do not remember much about version 2.4, except that I tried it and did not like it for one reason or another, and went back to 2.3.

AFAIK, it IS enabled for looping. But, I don't know if it actually looped, though. Could it be the loop is TOO short for Kx drivers to detect?

Sounds like a saw/pulse wave to me, now. That's strange how the arrows show 36, while the Local Loop End is 20, according to Vienna....

Not so, for me. In Viena, i clearly hear a sine wave-like tone, while in Vienna i hear clicking or ticking (i.e. noise). I recall, when i had CL drivers, that it sounded like a sine tone, too.

Well, i never edited the file with Viena, in the first place. I only played it there.
