This is an early beta of the revised P3 OS discussed recently.
Read the release notes carefully before you decide to load it, it is 
still quite some way from being finished.
And let me know how you get on with it.

The release notes are an interesting read. I can definitely envision
how this direction would be useful. I won't have a chance to dive in
soon, but with an extra P3 at hand, will try to schedule some time in
the next month or so to play. 

Off the top of my head, I like the idea of fixed banks and available
bars/patterns, with dynamic allocation of memory.

Looks interesting, and I don't see any drawbacks compared to the  
current playlist scheme (well, apart from the fact that the  
silkscreen printing on the P3 will now be wrong...!).

I'm sure you know this, but: you'll presumably need a percentage-used  
figure for the pattern memory at some stage...?

You can replicate anything achieveable with playlists, though if you have a
playlist with the same pattern used on a number of steps, with different
transpose values on each step, you would need to use duplicate bars to
achieve the same thing in a v4 pattern.
But unless you make heavy use of that, it shouldn't be a problem with the
improved flexibility of dynamic storage.

So far there are 255 bars of storage space because I'm only using single
byte pointers to the bar storage.
I will be extending the pointer size to 2 bytes soon, which will allow the
maximum available RAM to be used for bar storage.
Ultimately the current P3 hardware will be able to hold at least as many
bars as there are currently patterns, possibly a few more.
Though I do have a scheme to add memory paging on a RAM daughterboard that
would allow over 3000 bars storage.
That would depend on demand though.

hey colin,

just played with the new beta for an hour now and like the changes,  
feels a bit
quicker going from simple patterns to more complex things - that is  
cool!
what I didn't get so far is how to change between the bars other than  
using the data button, reading your notes
I assume theres another way to select/jump to edit of a bar directly

btw. while you talk about RAM usage/organistaion I would love to see  
an additional feature requested some
days ago....
----
feature then where you play in some  notes into a memory buffer (i.e  
played.from an ext. keyboard)
and then insert notes from this buffer into sequentially every step
activated - its a bit like the old roland MC sequencers have worked.
you play in a small melody, then you create rhythm and lenght  
afterwords...
----

I'll test this beta some more during this evening.

cheers,
henry

The DATA knob is the principle method.
While you're in page 9 (bar edit), you can press the step keys to select
bars directly.
Ideally there would be an extra row of LEDs to indicate current bar, and a
dedicated 'bar select' button to use at any time, but I'm yet to find a
means to drill holes and mount switches in C.

That would take a hefty bit of re-coding to achieve in P3, record captures
data directly into the patterns at the current position, or step-by-step in
ARP capture mode. There is no separate record buffer.
Similar results could be achieved by having a way to insert gaps into an
existing pattern.
Then you could capture your notes using ARP capture, and increase the
spacing between them later.
I'll put it on the wish list.

yes  using the arp is a good idea, how would you increase the spacing  
in easiest way then?

C certainly lets you shoot yourself in the foot, so it's probably  
possible...

Hi Colin,

I enjoy the last beta improvements, really more intuitive without playlists.

And now randomize & sculpt go all over the pattern, nice.

A question in pattern edit mode, could we get a scroll mode who follow each bar of the 
pattern automatically ? (wd be good to have that in more of the data knob)
Another one, why in the user config, Middle C option is C4 & not C3?

Thanks, P3 is still updated, that's great.

best regards 

jerome

I was going to add that at some point, though it could be tricky to edit
patterns if the bar advances just as you are about to press a key.
It would be more use to view the pattern than for editing...

> Another one, why in the user config, Middle C option is C4 & not C3?

There is no standard definition of middle C for a given note number.
The user config option lets you choose one of the common ones as an
alternative to the (more logically correct ;-) P3 default of C5.

Also for editing, by pressing the "hold" key while playing ;)
