yo this is pretty much to nym cause it seems like you have done your testing on os2. I just got it and i was looking throught the online manual and i come across this http://www7a.biglobe.ne.jp/~mpc1000/os2/mixer_e.htm which i want to experiment with but i see no way in the manual that corresponds with the machine on how to get to this screen. help pleas.e

mode+pad 4 will take you to the track mixer.
hit the lit MODE screen while in the track mixer to visit GTE, global track edit. turn the mixer type from TRACK to PGM to get the different visuals in the track mixer. i don't fully know the ins and outs of this function yet but if you give me pointed questions i can do more to study em up

thanks man. greatly appreciated. no specific questions so far. but i don't really have time to go in depth experimentation cause i have a new years deadline that i am meeting. tiny question was the ring modulation feature in os1 and i just missed it or is it new cause either way its tight,

ring mod is in os1.
i actually haven't used it too much yet...

man you should i just made full synth patches by looping small portions of recorded scratching and changed it using the ring mod and then i put it through the ADSR thing. JJ has succeeded, my jaw is dropping literally every other minute.

1.how small a cycle can you loop

2. and can you modulate the loop points

3. can you modulate the start and the end of loop points individualy as well as together

4. can you automate all of this?

thanks for getting into this

1. You can cycle as small as you want to make it.
2. I'm not really sure what you mean by this, i mean you can modulate the sound, but i dont really see what you mean by modulate the loop points.
3. Again, like it is one sound i don't really see how you would differentiate between the two
4. I see no way of automating it, but i don't see why you would want to because with experimentation with these techniques there are infinite sound possibilities.

re: 2. - i think monk means can the loop start and end points be moved while in performance, like the ensoniqs and bigger akai's can, they can be linked to modwheels, and midi CC's in those other samplers.

if this is what 'monk's touching upon - and i hope so - its quite a powerfull technique of having a tiny wave cycle and modulating their starts n ends, changing the shape of the wave itself as it loops - its called a 'transwave' (cos its a wave"cycle" thats in transient - moving, and can lead to awesome sound shifts - considering the tiny amount of sample memory used).

yo - monk,i was gonna say theres absolutely no way to do this yet - but, and i know its not really loop mod behaviour - cos i dont think jj has coded that in yet to either os1 or os2, but u might be able to create similar effect by using moving start end sample points while retriggering instead of looping , in the slider-note on: s.start/s.end parameters.

damn....now u just got me thinking of the removal of vel>s.start (found in jjos1 - amp env) one of my saddest os1/os2 cuts.

oh yeah, that's exactly what i was talking about, I started on the eps 16 then plus, then asr10 :) would love this feature, will give your tip a shot

shit which was the last os version that the sample velocity to start was in and which was the last os version that the mutes were acting right?

thanks for the info

all the latest os1 (4.9x) can do vel>s.start - look in the amp pages,
and also if u like , the slider pages, note on:s.start, i think the most neat is 16 levels, set to velocity, while the Amp=vel>s.start, u get 16 discreet velocity values = 16 steps for your sample, so u get a non destructive chop without being in os2.

when u mean acting right u mean oneshot mutes/unmutes were ideal - was 4.84, but there were issues with polyphony/voice use that seemed to over-allocate voices in 4.85 and higher - so was difficult to use some heavy sequences - yet in earlier versions (4.84 and lower) these 'heavy' sequences play just fine.
