emusonacid!

Hi,
I would like to discuss two methods for sample insertion into sample, but in both method, i found serious problems. Anyone experiences this before?

1. Last year i put most of my samples - mostly the long ones - in the way, that my computer (EMU 1212M) connecting to the sampler via spdif/AES-EBU cable and simple record the incoming signal. It's bad becouse i needed to cut the samples after i recorded them. The second problem was that all of the signals in the digital domain changed their phase (yes i tried lots of cable and programs, and etc.).

2. Using Zoeos or Sound Forge's SMDI transfer through the SCSI card. There are also a huge phase problem. Finally i generate a simple 10 second 440Hz sine wave (in any audio program, like Audition or Samplitude). After i inverted the phase and save to another file. If you mix them in any available program, the waves cancelled and you hear nothing. And this is correct. But if i transfer these wave files through SMDI to the sampler, and make a voice include this two waves, you hear the waves - or something! The waves aren't cancelled!

Anybody know a solution for this problem?
I use two of this emu ultras in live situation, and it's essential to be everything in phase....

How about you edit your samples in soundforge then save them to zip
load the zip disc samples into the emu
You will of course need to be running eos 4.7 (reads fat formated zips)
Best done by connecting a usb zip to the computer and a scsi zip to the emu.

Thanks, but i tried (t think every) method for this. Using the old floppy & ZIPs to transfer the original WAVE files (both the original and the phase inverted version are exactly same long, etc..).
I prefer to everybody try these, maybe somebody have a success on it. This is a serius problem, i think this the most significant building block to mix sounds together. If this first criteria fails, the whole thing is a bullshit. I like really much my EMU Ultras, but this is a nonsense!

very odd
I wonder if the processor has a slight lag beteen sounding the 2 samples
if so the phase cancellation will not be total as the wavforms will not be entirely opposite one another and this would cause you to hear some sound leak through
This is not a great explanation and maybe wrong but other users have said the the sampler has issues with timing when trying to create precise drum grooves (timing to loose) I thought that this was a issue with midi but then again it could be the processor

I believe the sound engine of the EIV requires one or two (can't remember) all-zero samples before and after the sample to do its pitch interpolation. If the imported sample doesn't conform to this, it adds them automatically. Could this be the offset you are seeing?

Unfortunetly not. I tried with different amount of zero samples before and after and both....
MIDI is also not a problem (try it with one voice in multi-sample mode - so one midi signal starts both samples; and with two midi signals for two different voices, each voice content only one of the sample). Also tried to control the midi events from a software sequencer (Samplitude), change the midi resolution to extremly high, and can perceived the differencies (more/less loud the two sample together), but cannot find the exact point. It was a really boring day.... ;-)

Btw. last year i tested an AKAI MPC2000. It was hundred times more terrible in this view. The tempo of the same WAVE files were different if i started them from one MIDI command: started in phase, and slowly changed the speed. In a 40sec drum-loop, in the 25sec point, you heard the out of phase, and ticks doubled..... And thousand of people works on this "instrument".... :(

Btw. thanks for the ideas.
