Gigastudio 3: hit key c4 and hear g2

[Rüdiger]

I recently installed Gigastudio 3.
If I now hit the key c4 (with several piano libraries) I hear g2.
What is that?
How can I change this?

Thank you for help

My first guess is that your midi keyboard may be transposing the notes before it sends them to the computer. Check out any transpose settings on your keyboard. :)

[Rüdiger]

I just tested it.
My Gigastudio 3 is running on a new PC.
My old PC with gigastudio 2.5 has the same libraries and the same midi-keyboard.
I hit c4 and hear c4.

I think it is something else?

Thank you for the quick help.

Sample rate mismatch? Between your sound card setting and the gigastudio setting, or between an external clock source and the sound card?

I had the same problem. And sometimes it reoccurs....haven't figured it out yet, but I can reboot and it works properly.

[Rüdiger]

I think the "sample mismatch-idea" from quqliel could be right but I don't understand enough from this topic:

In gigastudio 3 with sample rate 44.100 hit key c4 (middle c) sounds as g2.
With sample rate 96.000 hit c4 sounds as c3.
Further the pitch of audio cd's ist too deep ( as the cd is moving too slowly) for all sample rates of the sound card (echo gina 3g).

Now I have deinstalled gigastudio and newly installed the soundcard.
The pitch of audio cd's is still too low/deep.

I do not know what to do. I appreciate every help!

If gigastudio could handle 188.000, then you'd be in tune -- maybe the soundcard is OVER-capable, and should be configured at a lower setting?

[Mattias Henningson]

If you run out of possible configuration issues contact Echo support. They are doing a great job and will get back to you within a day or so. I have a similar problem with one of my Layla 3G cards. No matter what I do the audio is played back in the wrong speed/pitch. The card worked great for about a month and then suddenly started to misbehave. It could be a driver problem or a hardware problem. They apparently have fixed something with clock chip resets recently in the driver but that version is not released yet. I had to proceed with my project and simply replaced the card with my old Delta 1010 I had on the shelf for the time being which means I still haven't tried the fix. I've promised myself to do it any day now... :)

thank you quuiel, thank you Matthias:
I tried all possible sample rates (from 32000 (?) up to 96000). Isa the the sample rate get lower the pitch ist going lower. There has been a 'jump' (from 32000 to 96000), that worked one time (for audio cd) but I could not reproduce it permanently.

I will contact Echo.

The pitch should NOT change when you change the sample rate of the sound card. There is some other component in the system which is detuning the sample rate.

Try "locking" the sample rate on the driver, and see if this solves the problem.

Are you using word clock or lightpipe/spdif inputs in the system?

[Rüdiger]

Bruce: thank you!

- I locked the sample rate at 44.100 in my soundcard (Echo gina 3g).
Audio cd: pitch false (too low).
Gigastudio, also 44.100: hit key e5 results in sound c4 (middle c)

- now the same with 96.000:
audio cd: same result as above with 44.100
gigastudio: hit key f#5 results in c4

- the card has digital inputs (SPDIF RCA, SPDIF optical, ADAT optical),
but I have no external digital input connected. The only connections I have are:
monitors to analog 1,2; headphone; midi in.
Grean lights are on showing according to the manual that the card has „detected“
„a given synchronization source“. The manual says further: „in order for a digital inpout clock to be detected
the console must set to the appropriate digital mode“.
If do not misunterstand this my card shows the digital mode SPDIF RCA.

Just a thought, no harm: check the samples are mapped properly: -Check the waves in the wave pool (I don't have GS3, in GS2 you R click on the individual waves and select properties). C4 is a default assignment and perhaps something happened to the Gig file.

[Rüdiger]

I think now that the problem is too complicated for me (cd audio pitch false and the problem with gigastudio) and I contacted Echo. I consider to replace the card and buy a new card, although gina 3g was rather expensive (349 €).
When/if there is a solution I will inform this very helpful (!) forum.

Rudiger,

Your problem sounds very much like an invalid wordclock source.

Forgive me if you've already tried this or if I'm oversimplifying things but have you tried making sure the "input clock" is to "internal" in the Echo Console? This is critical if you don't have any digital inputs hooked up.

Hope this helps,
Crispin

[Bruce A. Richardson]

This is not a GigaStudio problem. There is some serious problem with either your soundcard hardware itself, or with some software component which is "kidnapping" the sample rate.

You should definitely pursue this with Echo. There is no way you should be having these sorts of problems. What seems to be happening is that the audio interface is choosing a sample rate of its own liking, with no regard for what it is being instructed to do by the software. Matching a "locked" rate on the Echo card with the same rate in GigaStudio's configuration should (and must) produce output of the correct pitch. If this is not the case, I cannot think of any situation other than a defective card which could explain this phenomenon.

Locking the sample rate on the card, by the way, was a diagnostic idea...simply to determine what was happening. Ideally you should not "lock" the rate.

Be sure to turn off all the system sounds, etc...ANYTHING at all in your computer which could be accessing the sound card besides your music production software.

[Rüdiger]

yes, I informed Echo allready.
Crispin: The input clock is set to 'internal' (green light on) (and 'MTC').

from Bruce:
"Be sure to turn off all the system sounds, etc...ANYTHING at all in your computer which could be accessing the sound card besides your music production software."

The guys who make my music PCs insist that I remove windows sound sets. They reckon that simply allowing windows to access a sound with, say, a 22kHz samplerate can cause the system clock to stay switched to that frequency - which will screw up the tuning on any software which relies on the internal clock for sample rate.

[Bruce A. Richardson]

I have found that to be true in some cases. Sometimes the offending application will "let go." Sometimes, it will not.

[Rüdiger]

I contacted Echo:

They reacted very quickly and send me a new patch to update my driver.
But this not solve my two problems.

I reported this to echo in detail. Today I got the answer (also very quickly).

"It sounds like you have a bad unit...Please contact your retailer for an exchange".

at the weekend I got the new soundcard from my retailer:
M-Audio audiophile 192 PCI.
All works fine. CD-audio no problems. Gigastudio 3: c4 sounds as c4, sound-quality wonderful, gigastudio 3 wonderful.

Thank you all.
