I have an Oberheim Matrix12 with a gorgeous sound I'd like to sample for use in GS.
The sound is like a shimmering bell. It has a fairly sharp attack, then begins a slow decay....about 7 seconds... to it's hold amplitude . If the key continues to be held down, the sound remains at this intermediate amplitude and, even though there is a fair amount of phasing going on, it is loopable.
When the key is released, it sounds as if a low pass filter is progressively applied to the sound over a period of 1/2 second.... causing a moderate attenuation of the highs in the sound. After that, the sound decays into inaudibilty in a matter of about 7 or 8 seconds.
I've been thinking that I could capture this sound by using the initial portion of the sample (up to the key release)... for the start of the sound, and then using the portion when the key is released as a sample triggered by the release trigger.
I have a feeling this might not work, because the sound is fading over the first 7 or 8 seconds. Since my release sample will have a certain amplitude, how can I ensure that there isn't a "bump" when I the release trigger sample kicks in.
If I release a key after a short period of time, the release sample will seem to be too quiet, since I would probably have played a fairly long note when sampling (and the sound is probably 1/2 it's original amplitude when I release the key).
Is there a way to cross-fade between the end of an initial sample and the beginning of a release sample?
I would think recording a piano has a similar problem if release samples are used.
Any help would be much appreciated. I think I could spend a long time spinning my wheels on this one and get nowhere.
