Im wanting to use an mpc 1000 with my midi keyboard controller similar to how i used to use my akai s5000 rackmount unit. I had it set up with 3 synth sounds spread over 3 octaves ( 1 octave for each sound) and the last octave had one shot samples and loops. Is there a way to do this with the 1000? My s5000 was damaged beyond repair in a flood. Any help would be much appreciated.

I am using JJOS 2

I believe the solution is in the INST type program. I haven't actually used these, but as far as I know, they're made to do similar things to a keyboard-based sampler, like mapping a sample chromatically across MIDI notes.

Someone else who actually knows how to use it could explain better than I, but in the meantime you could check out the JJOS manual.

There is a dedicated forum for JJOS users, I'll stick this in there as I'm not sure how JJOS handles instrument mapping/ keygroups.

THe instrument program will not allow key split OP> so this is not an option for above problem. I would suggest you actually make a program your self of this. Just put a sample in the program and use pitch to make chromatic scale over octeave and then do same with other sample for other octave and assign the rest to last bank,. Very easy, and just take s a few minutes.

Not True. I just tried it with my MPC1000 running JJOS2XL. You can do key splits in an INST program.

1. Create an INST Program
2. Layer all of the synth samples you want to include in the program.
3. Adjust the low and high key range of each sample layer in such a way they do not overlap, hence creating the split.

For example:

layer 1: Minimoog sample key range C1-B1
layer 2: Virus sample key range C2-B2
layer 3: Prophet sample key range C3-B3.....etc.

That splits the keyboard up with three different synth sounds, 1 octave each.

You can also layer sounds by having multiple samples assigned to the same key range as well. The only major drawback with INST programs in JJOS2XL is the fact all of the layers must share the same filter, amp, and envelope parameters, unlike the MPC4000 which has an independent sampler engine for each keygroup.

That is not a keysplit, that is a velocity layer. Sure it might seem like a keysplit, but it is not. Also how are you gonna control your velocity layer, can you hit keys in such a controlled way that it will not trigger a different velocity layer, out of the 3 you made?? NOt as easy as it seems, and for me I already have velocity layers for expression, so that also precludes any velocity layers for keygroups. Its an ok work around, but to me it is not very workable, compared to keysplit program that you made. So to me its not an option that I would consider at all as it is limited to you being able to keep constant velocity range as you hit you midi keyboard, and we are not robots. So I would seriously suggest that you use velocity layers for expression and different samples, but also make keygroups split over the midi keyboard, this way you do not have to ever worry about velocity, and you get both expressive layers and a key slipt group. If you are generation Y and so want it now, then sorry, you do have to put some time and effort into these things, but it will pay off big time when it works. So do not be scared of doing a little bit of work to get there.

If you are referring to the pad layers in a "DRUM" program, you are in fact correct as for each layer there is a field called "V. Range" for velocity range. In this case, these are velocity layers.

However, I'm specifically talking about "INST" programs and in "INST" programs, there is no such field or parameter called "V. Range" for each layer (in JJOS2XL 3.18 which is what I'm using) so you can't select different samples to trigger at a different velocity ranges in "INST" programs. In the "AMP" tab for "INST" programs, there is a "Velo. Level" parameter but that effects ALL of the layers within the program, not EACH layer like in a "DRUM" program. The only parameters that you can edit for each specific layer are the keyspan (low key & high key), tune, level, sample, and the original key of the sample. All other parameters such as velocity range, amp env, filter env, pitch env, lfo, etc are global to the program and effect all layers, not each of them individually.

So, as I said earlier, you can split the keyboard up by using keyspans that don't overlap for each layer. Since these are not velocity layers, you don't have to worry about different velocity triggerings conflicting with your keysplit. However, at the same time, you lose the benefit of expression as a result of not being able to have independent velocity ranges for each layer. So that's the trade-off. The "INST" program implementation in the JJ OS are is basic and limited compared to the keygroup program implementations of other samplers. It may be adequate enough to get the job done for some people, but not for others.

Well, from what I saw, there's no "V. Range" parameter for each layer in an "INST" program, if you found one, let me know because I sure would like to see it. I actually looked in an "INST" program for this parameter and couldn't find it.

Although I disagreed with you, I apologize if my previous response sounded aggressive. I'm only trying to help.

To cut to the quick, YES OP, you can easily do keyboard splits in JJOS2 with the INST program, as kvmoore stated.

In INST, just set your ranges and original key for each sample and boom... done.

yeah he is right. LMAO i never use it and have it set to full range as default. So I was wrong there. Its very obvious to, so I think I take it for granted and do not use it that way at all, ever as I prefer my method. sorry bout that. should have checked.
