I have some questions before starting the mission.
I mean, good on you man, it's definitely worth the time in my mind.

For Drum Kits... you'll definitely want a stride of one, and possibly multiple layers (the MPC can sample up to 4)
For general synths though... if there are a lot of FX... or BPM matching is important for example... you'll want a Stride of one... but for a lot of content a stride between 3-6 is probably fine. I would say the less "movement" there is between notes, the longer the stride can be typically. Experimentation though will help you learn what you do and do not like.
Straker wrote:2 Does it makes sense to put the tail to 0 (no tail) and then adjust the decay afterwards from program edit (adsr)?
Depends entirely on the sound for how much tail you need. The initial note held length is always one second though. Personally I try and capture a tail that is roughly how long it takes for the ADSR to let go or the reverb/delay to ring out.
Or... turn the FX off or set the ADSR on the synth you're sampling to have a 0 release. You can always try and replicate the FX chain on the MPC, and without FX it *can* be easier to find good looping points.
That said... I'd highly suggest turning looping off in Autosampler... I find it more of a waste of time and it can be quite distracting if you're not going to bother configuring it anyways.
For me... I'd say tail is usually three to eight seconds... just depends on what I am sampling. I've definitely gone as low as half a second. Do remember though... if you've got a crazy reverb that rings out for ten seconds, and autosampler is only recording the tail for two seconds, well that reverb tail is bleeding into your next sample... use this to whatever effect you may or may not want.
Straker wrote:3 For acoustic high quality instruments (vibraphone, EP) is it necessary to use a stride value 1 (chromatic) or using a 2 or 3 value is enough and unnoticeable?
In general, the less artifacts you want imparted due to pitch shifting, the lower stride value you want. On the flip side though, if you actually want to impart that characteristic, then sample with a stride of 12 or something. Depends how 'accurate' you want it to sound versus how much you want it to sound like a sampler. No art or science exactly here, just depends which you're going for.
Straker wrote:4 For continuos sounds like organs, is it better to again put the tail at 0 (no tail) and enable looping? Will it work?
I don't think putting tail to 0 is going to do what you want... you should definitely read up in the manual, or if you have it in Tutor's MPC Bible. The looping enabled in the autosampler isn't magical (although it could be in a future update)... but at least up to 2.9 firmware, the looper just looped over to points you specified and usually sounded pretty bad. Looping really requires some skill, an ear, and the patience to experiment for every sample. The fewer samples you have (or in other words, the larger the stride) the less work you have to do because there are fewer samples to get looping adjusted properly.
If you are looking to create flawlessly (or decently at least) looping samples, I'd also suggest you consider auto sampling in mono, stereo samples can be a real bear to get looping properly because you don't always have oscillator, phase, 0 through, or whatever alignment for a ton of reasons.
Anyways, hope that helps, and good luck!
