if after all this you still dont understand why the kp3 is flawed thats your problem and i really dont have the energy to explain it anymore. like i said, if you're satisfied with your gear, that's fine, but dont try to convince me that the gear works as supposed and that the real problem is my workflow. btw, the kp3 was the last purchased korg product and the korg gear is listed in my sig just so that people have an idea with what kind of information i can be of help and what korg information is relevant to me. i dont see the need for sarcasm here, this thread became a little too personal for my taste. maybe i lost it a little with the "korg bitches" remark, but one can only handle so much ignorance or bad will.

it's neither ignorance nor bad will. your tone throughout this entire thread has been condescending and rude.

i understand very well the problems with the kp3, as someone who works with microprocessors regularly.

the KP3 not capable of doing effectively synched BPM pitch shifting on the fly while playing effects and running other loops. there's a reason for this. say you're fiddling around with the BPM knob and you're changing it slowly up to 129.0 from 120.0 in 0.1 increments every half second. getting a synced pitch-shift takes processing time and power. for a completely effective pitch shift to happen, it would need to be "resampling" behind the scenes with every 0.1 increment. as a programmer i hope you can understand how this is basically impossible to implement with all the other things the KP3 has going on at the same time. hence, the need for the user to press 3 whole buttons and sample the sound at the proper BPM to get what they want. it's not the end of the world.

what's actually much more irksome is the inability of the KP3 to read a midi clock in properly. it's always jumping all over the place.

pitch shifting (as used in kp3, not the one which detunes a sample while keeping its length unchanged) is not a processor intensive task. as someone who was involved in the 90's demoscene and written my own .XM module player to use music created with FastTracker in my demo productions, who needed to support 16 stereo channels playing at once on 90's processors and eat no more then 5-10% cpu power, i should know a thing or two about it. pitch shifting doesnt take any pre-processing of any kind, its just a cursor that moves with variable speed through wave data and does interpolation on the fly. no need to resample internally anything ahead time. it may get intensive depending on the type of the interpolation filter used, but most of the time it's just simple linear interpolation between two samples or cubic interpolation of four samples (or two samples and two tangents) if you want true continuity between samples. so no, as a programmer, i dont understand why is not possible to do perfect pitch shifting in real time. even if the speed of the cursor had some precision issue due to fixed point maths used (for speed reasons or lack of floating point support), the cursor of all samples could be realigned automatically from time to time, say at the start of every beat.

anyway, i see no point in guessing what could be the problem and why loops dont sync. there could be a million reasons, but if all kp3 users would acknowledge it and not declare themselves satisfied with workarounds maybe korg people would get on their asses and actually do smth about it. but since we seem to be too busy fighting eachother, slim chance...

since you agree with this i assume you have taken the sync test or did a test with your own loops in the same conditions and found that loops dont sync. my question is: how did you vote?

So,,, Has anyone heard my loops go out of sink?

Do we have a Bontempi lover here, Yamaha, god forbid,,, Casio.? I'll accept Roland but I'll sneer. KORG RULE.

Bring any argument. I'll defend. I'll defend on the street, I'll defend on the beach. I'll defend when my fingers are removed. I'll still be able to play KORG! Can Technics offer this music creating ability? I think not.

i voted no. anybody who reads this forum on a regular basis is well aware of this problem.

good call on the difference in pitch shifters.

the difference is, i AM satisfied with the workaround. it seems completely reasonable to me that if i want to change the bpm on something and have it stay in sync with everything else that there is some work involved.

I totally agree with Sooshee.

A: The loops go out of sync.
B: This is not intuitive and disappointing.
C: (I guess) that this could be solved with improved firmware, if Korg are made aware of the issue.
D: That several comments on this subject are simply disparaging and seem to be intended to dissuade others for asking for help or getting involved in music. This is a real shame.
E: As a result, I am less likely to purchase more Korg equipment in the future (although I do really like my MK and KP3).

Don't give up Sooshee!

I agree with xmlguy.
If you use the Kaoss as an instrument for playing loops then you have to make your loops turn and this is live and direct.
