Walt, I convert all tempos and FPB (Frames Per Beat) within the Sonicfire Pro 5 sampler converter. I can also adjust them in Sony Sound Forge Pro 9 but usually never touch it there, because it is already done before using the samples. At 0:50, that is on purpose and intentional, listen to that closer, it end on a note and the keyboards start. As for the guitar sound between 1:05 (keyboards end and strumming of acoustic guitars (2 of them in sync) start with a cymbal splash in background) and 1:40 guitars end and orchestration starts. The acoustic guitars sound exactly the way (I) wanted them to sound for this piece, just like the electric guitars with their distorted gritty sound. I'm not getting what you mean by warbling, for the acoustic guitars, I thought they sounded awesome the way I edited them.
I know that this sounds not as good as the 292 mp3 version or the .wav files, but when loading to soundclick it never does sound as good as the original tracks. Could also be the width I used for this with the stereo imaging settings. The exciter imaging and compression and limiting are all good. Equalization, as far as, post-in and post-out are all good and so is the maximization settings. Not a lot of reverb on this and so I don't know what your hearing. Are you using headphone, computer speakers, or reference speakers. I use Truth Reference Speakers with 8" reference speakers in them and these speakers tell the truth. I think it just might be the soundclick player (the freebe one) could be the issue. I'll check it out again, but while typing this I listened to it and checked out those locations your talking about twice and I'm still unclear what your thinking. Anyway, thanks for the concern.
Peace and Blessings, John
