Re: [emax] Emax Sample Release High Pitch Noise

2014-07-05 by JAMIE logan

does it happen on all voices have you sampled rubbish at the end the vca in the ssm chip is analog and emu never fitted antialiasing filters in the the emax range in most synths theye have brick wall filters that are set to 10khz to 16khz depending on what frequency range of rom samples used this stops all digital harsh noise that is out side of this frequency range

in the emax your supposed to use the filter cutoff to remove the digital noise as those filters have a range from 40hz to 16khz frequency range just set them until you cant here the noise and also set the filter cutoff to envelope amount have less release than the vca and the filter will cutoff the noise before the vca has finished

if its only happening at the end and not during the sample we can say its not the dac as if it was you would have noise all through the sample does it happen on every voice or just one try truncating the sample emu when truncating leave several samples after the end or loop end for interpolation of the loop se if that stops it or have you already truncated it and it loops perfectly and just causes the noise after the end of the sample

listening to the samples they sound ok with either i would say that you have got some sample crap that you have recorded maybe some noise in the instrument but the shorter version does not sound any shorter than the longer version so move the sample end until you dont get the blip and truncate

your emax sound clear

It sounds like the Room where the sample is recorded.

BTW: a good method to check for residues of the valuable bits in a sample; is to reverse the sample - in the analog department if I remember correctly there is two ways to reverse a sample, digital module and somewhere in the analog department that makes it non permanent. By reverseing the sound you can hear if there is unneeded bits in the end.

Hi all,

Just wondering if this high pitched noise a the end of this sample is normal? I've noticed if I shorten the length of the MIDI note, the noise will go away. It's like it's some kind of high pitched noise that gets triggered after the same is finished playing. If the key is held down, you hear the noise.

I've attached both versions with the longer notes, and shorter.
