Folks,

There's a new firmware build in Yahoo files, with a fix for an 
obscure little bug brought to light by a sysex dump Roel sent me.

The bug itself amounted to a single 'B' that should have been a 'D' 
in a variable name, but the effects of it are rather unpredictable 
and potentially interesting.
Roel, it certainly caused the weird behaviour you were seeing with 
your Jomox.
Tom, it may also have caused your P3's odd behaviour - give the 
update a try if you still have your weirdness inducing bank.

The new build also has a feature that went in after Mr Nagle's last 
gig. This is called 'Safe Stop' for reasons that will become 
apparent...
While P3 is stopped, if you press FUNC+STOP a message will be 
displayed to indicate 'Safe Stop ON'.
If you press FUNC+STOP again while stopped, the status will toggle 
to 'Safe Stop OFF'.
With safe stop ON, pressing STOP alone will not stop your P3 running.
You must press FUNC+STOP to stop it.
You can probably guess what happened at Paul's last gig.
Fortunately his audience were too stoned to notice anything but an 
emotionally pregnant pause...

Other less obvious new features in this build are the sysex REQuest 
blocks, that will allow a PC based P3 librarian app to request 
individual parts and patterns, or indeed the whole memory.
There is a nice little application to do this already in the works, 
which I hope will see the light of day soon. It's being rather 
impressively written without the use of a real P3, so I expect great 
things when the author actually has one !

If you're paying very close attention, you may also notice that 
despite these new features, this build is smaller than the last one.
I've had my optimising hat on...

Cheers,
Colin f

I suspect his future gigs may be somewhat longer...

Oh boy! I just can hear mr. Nagle thinking about new features... :-)))

Colin, will mr. Nagle be sober enough during concerts to actually push 
TWO buttons to stop the P3??

I don't stop, I fade. Although I do have some new features in mind to
make stopping cooler.... 8)

Apparently they already feel like eternity...

Hi Colin,
I just checked the new firmware, and at first sight it seems that the 
problem of weird jomox behaviour has been solved. Thanxs for that, if 
I notice other weird thingies I let you know.
Cheers,
Roel

i've just come across something annoying with this 'Safe Stop' mode 
thingie; it's impossible to press the FUNC+STOP combination from 
playlist edit due to the assignment of the FUNC button in that mode..
(FUNC-button...sounds kinda like a swing function but hipper..;-)) i 
wanted to do this because i was doing some stuff with accumulators 
and i wanted to reset & restart them. not really a big issue as i'm 
not prone to mr. Nagle's acidentally-hitting-stop-syndrome so i'm 
in 'Safe Stop Off' mostly now, but i thought it was annoying enough 
to be worth mentioning.

I guess Safe Stop is of particular value for live performance. I
certainly only intend to have it enabled then - where it is vital for
a clumsy git like me. 

I think you may not be doing experiments with accumulators in the
middle of a gig - and if so, setting knobby control for accumulator
limits would be the way to go there I reckon. Possibly not a big
issue?

Damn - this is great. I've gotten hooked into certain advanced features, but
I think that I've really missed a lot of essential stuff...gradually making
my way through this tonight, getting sidetracked (mostly) because it's so
much fun. But I can't believe that I just haven't tried so many of these
features that I'll now find VERY useful. Ndub. Can't believe I haven't used
this. Love the hint about inputting unsynced notes from some other source
while this is recording. Spectralis is arriving maybe next week. This may be
key to some indecent relationship between them.

Will be very interested in your opinions on Spektralis - I am supposed
to be getting one for review sometime but the UK distributors seem to
be dragging their feet.
Glad to be of service.. :-)

I don't think that the distributor is dragging its feet - there have been
quite a few delays in production - but it looks like it's finally being
finished...looks like maybe I'll get one (I should be in the first
shipment), I'm hoping, by the end of the year.

Hi,

Just a little thing ... How random is the random function of the p3. I 
explain : if let the P3 play for a long time, will i finally have a pattern?

Just curious,
Tom

Well, you had to ask...

The random number generation in the P3 is, like all programmatically
generated random numbers, really a pseudo-random sequence - a predictable
sequence of numbers which has many of the statistical properties of a random
sequence.
A maximal length linear feedback shift register is used to generate a
pseudo-random bit stream.
Every P3 will ultimately generate the same sequence of bits, but each starts
at a different position in that sequence.
The start position is determined by the random state of the bits in the SRAM
chips the first time you power your P3 up, or after a backup battery
replacement.
The length of the sequence is 2 to the power 64, minus 1. But since the
sequence is of single bits, eight iterations are needed to generate a random
byte.
If you generated a pseudo-random number with P3 one hundred times every
second, after seven hundred and thirty million years, you might notice the
pattern repeating.

Cheers,
Colin f
