legs, i'll get to it. cursory reads/thoughts were positive, i like it but in some ways it's something i'm aware of but not familiar with. i understand the results but need to grasp the mechanicals a bit more before making a better comment on it.
tony - the difficult thing in trying to explain what you can do with this os is that it is so jargon-laced.
drums: first, simult.
simult allows you to link to pads so that when you play 1, you also play the other.
it's like layering sounds on a single pad, but allows you to do more than just stack em, because this way you ca filter em differently, pan em differently, and most importantly "ADSR" them differently. ADSR is, very simply speaking, the physical shaping of the sound wave. think of COMPRESSION like squeezing - while ADSR is "carving."
second, the sequencer. i mean what can i say - it's my favorite midi sequencer. of all the few i've used i've liked this the most. in the way i use it i find it easy to navigate and really easy/effective. the specifics here are many and nuanced.
as for chops, jjos allows me to slice every sample note for note, so that every single sample consists of 1 recorded note. i can use the sequencer to then rebuild/reinterpret the sample in any way i want, using the sampler's MICROLOOPING style capability to make any 1 note as long or as short as i want, without the objectionably unrealistic sound of timestretching.
i feel bad constantly linking to my videos as much posted material gets old, but:
http://www.youtube.com/watch?v=gbqXKwXoImci dunno. i feel like trying it to explain it in so few words is kind of weak. if i were to really sit down and explain the potential of the feature set in jjos, i could slap a title on it and call it "beatmaking in jjos."
