Just in case that wasn't clear enough, I'll just step through the process:
- Starting from a blank Song.
- I create an 8 measure (measures 1 to 9 for example) drum loop on track 1 in Song Mode.
- I enter Integrated Sampling Mode.
- Within Integrated Sampling Mode, I enter the Rec submenu.
- Within the Rec submenu, I select Keybank C 3, and Track 02 so as to not collide with my drum loop's MIDI on track 1. I set the Input Source to "resample" and the Recording Type to "sample". Mono/Stereo is "stereo", Record Next is "off", and Frequency is "44.1kHz".
- Within the Rec submenu, I enter the Standby submenu.
- Within the Standby submenu, I set the Trigger Mode to "meas", with Punch In/Out set to "001 - 005".
- I proceed to resample.
It's after this that I'm having some issues. When editing the resampled audio in the Trim submenu, I notice that the length of the resampled audio exceeds that of 352800 samples, which would be the entire 4 measures -- that is, measures 1 to 5. Using 44.1kHz as a sample rate: Recording at 120 beats per 60 seconds, each beat must take 1/2 of a second. If 1 second contains 2 beats and 44100 samples, then 1/2 of 1 second must contain 1 beat and 22050 samples. Not trying to be patronizing by the way, I'm just not great with conversion and it helps.
So, to conclude, if 4 measures contains 16 beats, and each beat contains 22050 samples, the total amount of samples in the resampled audio should be 352800. When toggling the built-in Tempo, Meter, and Measure parameters to reflect 4 measures at 120BPM, whilst setting the Start Point to 00000000, they also result in setting the End Point to 352800. I'm confident that by doing that, I've set the Start Point and End Point to encapsulate the "realtime" equivalent of 4 "musical" measures.
After extracting the audio, I'm left with precisely 4 measures of resampled audio. By now you may be able to see what I'm doing. I'm essentially bouncing my MIDI into a Sample Track, by loading drum loops into Keybanks. But the thing is, I intended to split the 8-measure drum loop into 2 4-measure drum loops. To do this perfectly, I'd need to repeat the above steps with measures 005-009, right?
I guess not, because if I do the exact same thing with the next 4 measures, I still get a large click/jump when playing the second 4-measure loop directly after the first 4-measure loop within the Sample Track in Song Mode. To clarify, in Song Mode, I press the EDIT button whilst selecting track 2 (the sample track) and manually program the first and second 4-measure loops to last 16 bars, and begin one after the other. Like this:
001 01 000 C -2 016 000 127
005 01 000 C#-2 016 000 127
I'm left wondering if there is a way I can sequence as above, without any large clicks/jumps? If the total length of the resampled audio contained only the 352800 samples between measures 1 to 4, and 5 to 9, I imagine there would be no clicks.
Is there a way around this? Is it random how much time is inserted before and after the resample when punching in and out? If it isn't, I'd like to know how much so that I can take it into account. Yes, I get it, it's petty.
