Hello,

I see the Synth Attack setting in Master/SetUp/Tune (F4)

Does anybody know what this setting stand for ?
(I can't find a comparable reference in the manual)

I use EOS 4.7

If you set it right, you get to watch a few videos where synths attack there owner. The one with the Moog Modular chocking his owner with a patch cord and then dropping one of the mod on his head was classic....

But seriously.... What machine are you refering to.

If it's what I think it is, then it's in reference to the amp envelope and that would me the way a sound starts. There are four stages to the amp envelope. ADSR is what it's called. Attack, Decay, Sustain and Relaese. So I would think it might be a global setting for the attack of your sounds.

I also don't think this is in regards to the Emu Ultra samplers...

Any one else have any ideas?

mmhhh ... perhaps it?s for the "Audition " Button ?

yes, i don?t know, there is no reference in the Manual.

It?s funny for me, i never saw ( used ) this parameter...

So, i am also very interested now in what happends with this Fast/ legacy parameter..???

I've got a feeling it's listed in an addendum somewhere but I might be wrong.

The next bit is such a vague memory that I may have dreamt it . Was there was a software update and a few keyboard players noticed a difference in the feel of sample playback? If so I think the feature was added so that you could swap between the 2.

Didn`t found it, there is nothing in 4.6 and 4.7 addendum.

But perhaps there is a 4.62 addendum out there?

Actually, I've been wondering about this my self, but have not found any explanation to it anywhere.

that?s absolut correct ,chubby!

I asked Andrew Longhurst (former "emulaner") a few years ago. And he told me the same things about the samples/ sample start in old emus and the ultras.

Can you give an explanation of exactly what this setting does? I just noticed it and can't figure it out.

Regarding the SYNTH ATTACK settings there has been given an explanation from EMU some time ago.
In the original question a user described some kind of FADE IN when playing percussive sounds and asked for assistance from EMU Support.
Here is the posted reply:
There is in fact a default SYNTH ATTACK setting in the sampler. Older Emu libraries were designed with a small default sample 'fade in'. Because of this...and because the unit ships with the CDroms designed with the fade in....the default when you update your software would have SYNTH ATTACK set to LEGACY. This setting can be changed to SYNTH ATTACK: FAST. This is set in the MASTER - SETUP menu.

From this I conclude:
FAST means, that there is no fade in at start of sample playback.
I also contacted EMU Support regarding the SYNTH ATTACK settings.
I received a response from Andrew Longhurst, where he explained that this "Fade In" was for preventing some Click Noises at the beginning of the samples!

Here is an example to visualize the effect and differences:

From the EIII-Library I used the following sound for demonstration:
CD-ROM: Volume 8
Bank: Prophet Five
Preset: 012 Drum Energy

My Setup:
E4XT Ultra, 128MB, EOS 4.70, RFX32-card, ADAT I/O, 4 analog In (RFX), 8 analog Out (RFX)
The ADAT I/O is connected to a RME HDSP9652 PC-Audiocard.
Used Software on Windows XP: Steinberg Wavelab 4
Used sample rate & resolution: 44.1 kHz, 16bit, stereo

Because of the RFX card, I made some modifications:
- Sample s070 Drum energy was converted from mono to stereo to prevent the “panning bug”
- Chorus amount in the preset was set to OFF
- In the cords the „VEL<“ – „AmpVol“ was set to 0%.

To see the differences of the “Synth Attack”-setting, I recorded the same sound directly with Wavelab twice, using exactly the same settings, except of switching the parameter “Synth Attack” from “Legacy” to “Fast”.

During the recordings I was allways in contact with MOSROB, who was very helpful in explaining some technical aspects.

In the screenshot you can see the difference between the both Synth Attack variations.
The attached picture of a stereo-sampled waveform is a combination of the waveform with the Synth Attack set to FAST (upper waveform) and the Synth Attack set to LEGACY (lower waveform).

Both waves are the RIGHT sides of each stereo-recording.
I made the recordings with some silence at the beginning for moving the "Fast" sample to the correct point for better comparison.

The fact that there is some silence before the sample starts does not have a specific meaning.
(Mosrob had the idea to do the job with the internal Resampling function of the Ultra. To see how fast the Ultra response to a "Note On". But on each resampling (auto truncate was disabled after resampling) I noticed different response times! From 6ms to 25ms! So I came back to the old school recording)

For the first time at sample point 98 the „Legacy“ waveform is identical to the „Fast“ waveform.
So the sample FADE IN is between sample point 44 and 98.

very cool. thanks for sorting that out
i always knew it was in regards to attack time but personally never noticed an audible difference when switching between the two.
