where is the chop (on / off /#) info actually saved?

the settings are obviously adjusted in trim first, but then the GPE has the ability to edit chop#.

so if i get a load of samples - make a program with them all.....

then i want to copy the program - the copy to be similar - but with choppy capability, i go to the samples in it - set up their chop to on.

if i was to save both programs, their samples are obviously shared, but now with chop on. so the behavior of the one that was employed to use non-chop samples is gonna be wrong.....

therefore do i really need to duplicate all the samples now? seems a waste of space - ie: if things were a bit different, the program could control the 'deployment' of the chop function on samples used elsewhere in other non-chop programs.

just to be annoying - i think ive resolved it - (its a self resolving issue, depending on the user!)

all tracks using the non-chop program were going wrong because i had (inadvertently) had chop# info in the seq, yet setting any events with this to '00' did the trick, ie: they DO play a whole sample - note on style (durations intact).

so as long as the program may have 'chop active' samples in it, the event info in the sequence governs the use of the actual chop bit, and in recording, so this should be set correctly by the user before recording.

it got me i think because of my sporadic work methods......creative juices and logical systems - like oil and water.

but still, my question remains...

where exactly is the chop info stored?

• the chop 'active/inactive' in the sample info?
• the chop '#' in the program? or sample? or both with a 'program overrides sample' rule?

chop info is saved with the sample. if a sample ndc is on , you will have the option in the program to set chop to 1-32 or to --- if you just want the sample to play back as normal, you dont need to make duplicates of the sample.

if sample chop is off in the trim screen, you wont be able to trigger chops from gpe.

if you save just one sample, you can load it back up with all its chops in place. turn chop to off save over the sample, reload it and turn chop on - and all your chops are still where you set them (similar to how loop points are saved with a sample).

so if the chop 'on' is saved in the sample data, and the sample is WAV format, how does this affect the actual WAV file?

would other WAV reading apps be able to 'see' the chop details? like recycle, or apple loop utility?

i rememebr someone here saying that wav files have meta data relating to cue points, im not sure if this is exactly what jj uses though or whether you can see them in editors.
I also remember seeing someone posting an application that translates jj chops for editing in cool edit.
