Analogue-sequencer

Hi,
from when i've installed the latest beta seems that sculpt and randomize 
function
work differently on my p3: when a pattern is running if i press f1 and 
turn the data knob
the changes to notes happen a bit later, seems only the next time the 
pattern is played.
Is it a normal behaviour? I don't remember was so before upgrading.
I've been busy these days so perhaps i've missed some discussions.
Btw other things are ok, and i also like the new aux menu.
Thanks for any help.
Bye
D

This change is the result of another change made to minimise latency in the
P3 sequence engine.
The user interface code that handles sculpt and randomise watches the
current pattern position for the track being edited, and writes a new value
into the pattern memory each time the position advances.

The change I made to reduce latency was to move the loading of pattern data
and handling of aux events from the start of each clock pulse to the end of
the previous one.
In the old code, with a heavy load of aux event processing, there could be
as much as 3ms delay at the start of each clock pulse before MIDI data
started appearing.
This change means that the UI code doesn't update the pattern memory until
after the data for the step about to occur has already been loaded.
I can probably restore it to how it used to work with a slight change of
implementation, if it's a problem.

I haven't installed the beta yet (I'm sticking with non-beta releases for
now), but I use sculpt and randomize all the time. That I can hear what
I'm doing immediately is necessary. My other sequencer, the MC-909, has an
x0x sequencing mode that is really annoying in that the changes you make
don't appear until the pattern starts again. I bought and built the P3 to
get around tne various idiocies of the 909. I don't want it to get dumb
too!!!

bleep.
out.

after using the new beta for a while,
i prefer too the previous behaviour of the sculpt and random,
i think it's better to hear in real time the changes,
also if it's not a big miss.
Btw Colin, can i downgrade to previous
not beta firmware without any risk?
