as i mentioned earlier this is not pro or contra the jj os and there might be many happy users of that os, but it does not solve my problems with akai!
all i want is akai to admit that they promised much and then let the users of the mpc 2500 alone in the rain, but updated the mpc 1000 os to get almost every feature that the mpc 2500 had and then concentrating on the mpc 3500 (that is sold as the mpc 5000

) and focusing all updates on that machine.
and now they are focusing on their controller range further exploiting the mpc name.
the jj os might be further advanced and in a state of constant development which is good, but i just want a official (final) os from the manufacturer of my machine that solves the remaining bugs and (if they are really nice) they can add functions like global programm edit.
there might be a lot of people that do not even consider to demand this from nukai, because they found another way to be happy and use the os of their preference.
my preference is to get akai to stand to their promises and deliver constant updates for their machines, because if they advertise it then it is a lie if they don´t do it!
fifty percent of the voters on this poll are also with me on this subject, so even if it is controversial there is obviously some people that are also thinking that akai has done not good with us mpc 2500 users and that they should do another os update.
and i am not saying this for a few days only, as some people think "what is he asking for after all those years? it is perfectly normal for any manufacturer to drop support for "legacy" products." i have been asking akai to do this for years! and i started to demand another os update just shortly after ver 1.24 was released! so here you can again see how nukai is treating its paying customers for years!
and lastly for the question of audio tracks vs. direct recording - i don´t know exactly (please someone school me on the options of the audio tracks on jj os) as i just us the akai os, but to me the biggest difference seems to be that there are just four audio tracks on the jj os and on the akai os with direct recording i have all 64 pads that can become "audio tracks". and also the direct recording function records sequencer data to fit the recording seemlesly into the sequence. this way is way faster for me to bring all my midi tracks to audio and all my external instruments without having to sample, chop, assign to program and then play the pad to my sequence. with direct recording all this happens at once - all i have to do is make sure the right (empty) program is active and then hit the pad i want my recording to land on after i recorded a take.
and one last thing that makes me want to have an official os on my machine is the fact that all the labeling is made for that os! that might be a dumb reason for some people to not use great new options because they are not written on the frontplate and i also wold be easy to make new silkscreen labeling, but i like my mpc to be as good as it officially can be.
peace, jo
