wHen I tune a single note in the seq edit window, all same notes in other sequences tune with it!? The same sample that is. How can I change this? So that when I tune, only the selected notes tune, not the entire sample.

Not sure if im following but ill have ago...
edit in the program
Make sure your editing just the one zone...

Havnt got the mpc here but it works...
can pitch any single sample in a prog up or down by .01%
Hope that helps...

no I mean when Im in seq edit window and select a note and push the orange key, I can change the tune and velocity. When I change the tune, the entire sample tunes with it.

For example:
Ive recorded a bassline on one sequence. ( bassline is a drum program with different bass-samples ) Ive copied sequence 1 to sequence 2. Now they are both the same bassline (seq 1 and seq 2). Now, when I tune a note in sequence 2 (seq edit), that sample tunes also in sequence 1. I dont want this to happen.. Can I change this? It must be possible cause when I play the bass with 16 levels tuning, the other notes stay in the same tune.

Do I make sence?? :?

I think I understand your problem. What you may have done is to copy and paste the midi notes which triggers the sample assign to it. You can tune a sample, but I believe you have to change the midi note in seq editior using instrumental track and grid editor. This will set your midi note to the right key C to G etc. Thus the midi note will play the right sample at the correct pitch. Midi edit on the MPC 4K remember. If you use the keygroup program for basslines you can have an easier time to tap in or strike the key you want to have and just transpose on the second sequence. The 16 levels tuning works like the previous mpcs and you can edit the tunings in step edit. But it is only temporary and goes off once you turn it off the drum program goes back to the original state. Any samples you tune will be changed but still have the same midi note assign thus all events will sound the same. I hope it help ya. Peace :D

so this is not possible with drum programs?

I'm not sure if I understand Haze's explanation. But here's my try: I think the tuning field of a MIDI note triggering a DRUM program actually changes the pitch of the *sample* in the program. I assume that's how the 16-level tune trick works for drum samples: the MIDI note doesn't change but you still get different tunings. How you gonna do that? Right, change the pitch of the sample.

If this is indeed the case, all you have to do is to make a copy of the program that holds your bass samples. No need to copy the samples, just the program. And have that second track use that new program. Now both tracks can modify their own program.

Hope this helps, since it's all speculation, and without a machine handy.

You got it, basically a drum program contains one keygroup per midi note. When you change the midi note you are changing the entire pitch of that keygroup. Midi 33 always stays Midi 33.

But a keygroup program`s keygroup can contain more than two midi notes thus it has a greater range aka keyspan. Midi 1 thru 64 aka C0 thru C8 something like that. You can go up and down the scale ranges consecutively at varying pitches.

Using 16 level tuning, it has a imitation keygroup program setting to increase the midi note range (keyspan) of a keygroup temporary in a drum program. But when you turn it off the drum program returns to normal.

Now if you copy your sequence containing the same midi notes in the tracks. The tracks in the sequence will trigger the same midi notes which will trigger the same keygroups in the drum program. Thus each midi note you change with change the keygroup in a drum program.

A drum program only has one midi note for each keygroup. In a drum program one pad has one midi number each. Even if you change the drum programs the track will play the same midi notes and whatever sample is within the keygroup of that drum program.

Basically drum kits , phrase samples use a drum programs.

Bass, keys, and instrumental notes use a keygroup programs.

Can you just use a drum program yes but it is extra work organizing the pads into a consecutive note number struture and then assigning tuned samples to each midi note. When on the 4k it is already done for us in keygroup programs. The previous mpc were alot of work (check the MPC tutors mulitsample program tips) to set this up. Like I said before we have to get into the Z8 sampler mode of thinking to get the full potential of the 4k. I hope it helps peace.

Kits -drum programs

bass, piano-keygroup programs

keep it simple. :D :D
