Play this in fb2k (my version is 0.8.1) with Order set to Repeat - after first repeat you will hear that for a second there is no low frequencies, like some high-pass filter would be applied. Hope you can reproduce it (it will be obvious to hear if you have big enough bass-speakers).
The only thing in my DSP queue is Advenced Limiter, turning it off doesn't help. It seems to happen on all outputs (waveOut, DirectSound, KernelStreaming). And what is most weird, it happens on this MPC encode only - when this sample is in MP3, OggVorbis, wav, or whatever format, everything sounds fine. FB2K's MPC decoder bug?

Edit1: Here's a MP3 version (which plays correctly after the repeat) so you can hear the difference more easily.

Edit2: It's not a MPC encoder issue for sure because on first playback (just after clicking the play button) everything sounds fine - the issue comes in after the repeat (first second of repeated playback).

Edit3: I removed the links from this post.

Hello?? Come on, this is serious! Anyone?

Reproduced.. how odd.

Reproduced here also. Weird.

apparently the problem occurs before the data leaves the processing chain (my money is on the decoder..)

here's a screenshot of the first ~1 second (1st playback and 1st repeat)

Yes, I reproduced it too . This happens if and only if your mpc is played after the same mpc. I mean, I've put it twice in the playlist (consecutive of course) and in the second entry, it happened. If any other file is played before (mpc, mp3 or whatever), it plays fine

Answered in mjy thread called "Bass Drop Our After Seeking". It's a limitation of SV7.0

Clarification at last, thanks.

it's taken care of.

Seems to be fixed in v0.8.2.
And I just noticed that there's a seeking issue with short files now: playback-position/seeking slider jumps back to the beginning after seeking, music plays back (seeks) correctly though.
