please explain these scale settings in INST program

MPC1000, JJOS2XL.

in the sample window of a INST program there are 7 columns. but for each sample a value for :
LOW HIGH ORG




as shown, the manual says LOW and HIGH is the range of the sample, and ORG is the original key.
ok.
but i fiddled with ORG and when i set it higher (in the scale) the sample sounded flattter and flatter .... and reciprocally, lowering ORG make the sample sounding higher pitch.
strange ... i am surely not a music theory expert, so what can i use LOW HIGH and ORG for ?
( ie, LOW HIGH and ORG are all editable but for what purpose since anyway i can always edit the sample TUNE value ?)

thanks !

Its like creating a keygroup which is the usual way of mapping samples in rack samplers.

Think about a keyboard in front of you. Now you can place a sample on any key OR you can place it on a range of keys with only one adjustment line. Thats called Keygroup
.
The LO setting is the lowest key the sample is mapped to (lets say C1 for example) the HIGH setting is the highest Key (lets say C3) now your sample is places from C1 to C3.
With the ORG setting you tell the sampler which key on the keyboard represents the original pitch/tune of the sample (the pitch it was sampled). If you set it to C3 the key C3 will play the original pitch of the sample and you only can play the sample lower than the original pitch (because of the range you set before. The sample won't play above C3).
The same goes on the other end. If you set ORG to C1 you can't play pitches lower than the original.
Now if you set it on C2 you can play the sample lower and higher than its original pitch.
Think about it what happen when you set the ORG to D2?
Yes, the original pitch will be played at D2 which means if you hit the C2 keythe sample will get played LOWER than the original pitch. Thats why you'll get lower pitches of a specific key when you set ORG to a higher note and get higher pitches when you set it to lower notes.

thanks for this. great explanation.
but if i understood correctly this means that these scale settings are useful only if i use a MIDI keyboard with my MPC ?

nope still useful on your pads as pad A1 represents note C1 all the way up to d16 represents note d#6..as though your pads are a keyboard so the same theory still applies.

ok, i see 4 banks, 16 notes each so 64 notes. a bit more than 5 octaves.
C1 would be pad A1
C2 would be pad A13
C3 would be pad B9
C4 would be pad C5
C5 would be pad D1
C6 would be pad D13
and D#6 would be pad D16

very cool.
