Importing keygroups with note stride larger than 1

I'm feeling a little lost in the weeds trying to accomplish my goal; maybe someone can help me figure out the best step-by-step process to get where I'm trying to get.

My goal: To import the sounds from a Korg Triton into the MPC Live in order to play them as keygroups from a MIDI controller

Using the MPC Live's autosampling function probably isn't going to be my best option, due to having to set the loop points myself. (I use a lot of string and pad sounds.) So I'm thinking Sample Robot software will be the best option for me because of its loop-detection algorithms.

I've tried messing around with the trial version of Sample Robot, and here's what I'm having trouble figuring out:

If I sample a program from the Triton using a note stride of less than 1, how do I get the MPC software or the MPC Live itself to fill in the blanks between the note increments I've sampled?

(Also, I'm having trouble figuring out how to import my own sample sets into a keygroup in the MPC software in the first place. Is there a manual or YouTube video that shows the step-by-step process of importing sample sets with all their individual notes, velocity layers, loop points, aftertouch, etc into an MPC keygroup?)

You cannot just drag samples into a keygroup program and have it map everything to keygroups and velocities etc. You can either autosample or load a supported program format - for keygroups, this would be AKP (the old S5000/MPC4000 keygroup program format), 50k (MPC5000 instrument) or XPM (modern MPC instrument). Alternatively build the instrument manually from the samples - I cover keygroup building tutorials in the MPC Bible. https://www.mpc-samples.com/product.php/268/mpc-bible/

Autosampler tutorial here: https://www.mpc-tutor.com/mpc-bible-tut ... tosampler/

If you need to have your multisamples nicely looped, then maybe sample robot is the way forward (or similar software, e.g. aWave, Translator). If XPM output isn't supported by your app, then Convert with Moss can convert into XPM from a number of other formats.

My experience of 'auto-looping' software is mixed, so if you want perfection you'll likely need to manually tweak various samples in each batch unless you are happy for 'okay' loops in some instances.

IF you don't want to loop, then you could just autosample in the MPC (the autosampler looping does not use waveform detection, just the same preset region in all samples

As for filling in the blanks, that's what the 'note range' setting in each keygroup handles, so that's either already set up for you in whatever software you are using or something you have to configure manually when setting up a keygroup program from scratch.

Keygroups and their XML format are a bit convoluted. I don't think there's any documentation so you'll have to reverse-engineer how they work. There are many elements and fields that are there but don't do anything.

The Convert with Moss converter software claims to support Akai keygroups, so that may be helpful. https://mossgrabers.de/Software/Convert ... hMoss.html

The tuning precision of sustain loops in Akai keygroups is functionally limited in how it's currently implemented in MPC/Force. There's a fine-tuning field for sustain loops in the XML, but it doesn't do anything. In practice, if you have a very short sustain loop such as one or two cycles of the fundamental, it will most probably be out of tune compared to the initial part of the sample before the loop. Without a working sustain loop tuning feature in the sample playback engine (MPC), the only possibility to fix this is to stretch/resample the whole sample file so that the pitch happens to align nicely with an integer-length sustain loop.

One more thing. I've been using Ableton Live 9's Sampler for exporting some sample programs to Akai keygroup format. Actually, one of the sample programs was even imported from (old) Kontakt format into Ableton first. The Force can import Ableton projects (from a suitable version at least) including sample programs - if you follow some limitations. Is there Ableton import in MPC?

Thanks for your replies. Ugh. It seems like I'm not going to be able to do what I need to with the MPC. I can't believe after all this time, no one has made a hardware sampler geared towards people who want to clone sounds to play on a keyboard rather than pads. There must be zillions of us out there who want our setup to be one MIDI controller and one hardware box and to be able to easily create keygroups from all our various synths and homemade samples. It seems like a company who made such a device would have no trouble moving product. I have so many friends who have been chomping at the bit for something like this for like two decades now. Anybody else feel the same?

(I realize the 1010 Nanobox Tangerine now exists, but it's hard for me to tell from the reviews and videos how versatile and tweakable it is. And it's just recently come out.)

Not sure I understand as the MPC does this through autosampler, it's a great feature. It will clone whatever hardware synth patches you wish, but you just have to accept that you'll need to compromise in places, mainly looping, but 'out of the box' it will do pretty much what you are asking for (i.e. easily create keygroups from synths).

But sample robot is also an option to 'prepare' instruments in advance. You just have to understand the limitations of the MPC when building in third party apps (e.g. 4 layers max etc).

I don't want to sound like a smart-ass, but if you don't insist on replicating the original sounds 100%, you will get something useful. A bit different but useful. Auto-sample what you can with moderate settings and try to work with what you get - it will probably be completely usable and it's completely up to your own skills, what to do with those samples. Add some sustain loops with cross fades, spend a few minutes tweaking the samples. If you want the exact same thing, trigger the Triton with MIDI.
