I just tried to apply Q-FX on a sample in the Trim/Loop page, and compared the result with the original. The resulting resampled sample is much lower in amplitude, not good.

I tried it again with a cranked up Master Level in GLOBAL, but that didn't help.

Then I changed the dry/wet ratios of the effects used in the Q-FX. And guess what, when set to fully dry, the resulting new sample is as loud as the original. Sooo... the FX section is causing the level drop.

Here's my guess: the change in the FX gain structure that was done in V1.6, causing a +12dB boost in the FX return levels, must *also* be done for the Q-FX resample feature. Good chance that there's a 12dB level drop here.

Anyone have a fix for this? Or should this go as a bug report to Akai?

I tried the Q-FX feature in the RECORD page, and compared the reported VU metering. With Q-FX applied (the same as in my initial test), the VU meters report a level drop of about 3dB. That's a lot, but certainly not as dramatic as 12dB. So maybe I had the same 3dB drop in the initial test.
