Analogue-sequencer

Folks,

Another P3 beta is in Yahoo files now - v3.1.006b6
Sorry if I'm working too hard ;-)

This build follows an upgrade to a new release of the sdcc compiler, which
reduces the total code size by a small but useful amount.
Compiler updates can sometimes make problems appear in source that worked
fine before, so this build will be tested a lot more before it becomes the
official release build. It seems to be OK...

Playing around with the additions to playlist edit mode tonight has been a
lot of fun, so I decided to post this one now, with the above caveat.

In the current playlist edit mode, to select a step other than the currently
playing one for editing, you must hold 'step' (F1) then press and release
one of the playlist step keys.
Since in 6 or 12 bank memory layouts, you never use the playlist step keys
*without* holding either F1 for edit, or F3 for length, I decided to make
the playlist step keys act as if F1 is held by default - EXCEPT IN 3 BANK
MODE, where you need the full range of 16 keys for pattern selection.
The playlist step keys will switch to Edit rather than Current mode, as
before, and the F1 key is still used alone to return to Current mode.
Editing a complicated playlist seems much easier this way, i.e. one handed.

The other new feature is something I've catch-ily dubbed QCPPC, for 'quick
contiguous pattern playlist creation'.
This is a much simpler feature than it sounds. ;-)

In the previous build, if you wanted to set up a simple playlist with two or
more patterns playing one after the other in a loop, you had to do a bit too
much button pushing - holding F3 to set the length with a playlist step key,
then selecting each step in turn and choosing the pattern.

QCPPC allows you to quickly create a playlist with up to eight patterns
playing in number order.
You can do this single-handed, in one step.

Just hold the pattern key for the first pattern in the loop, then press and
release the pattern number for the last pattern.
This will immediately modify the playlist such that each pattern in the
group is entered in ascending playlist steps, the repeats count is set to 1
and chg mode to P on each step, and the playlist length is set to the number
of patterns selected.

It's much the same as selecting a group of patterns on a 303 or 606, so I
don't know why I didn't implement it sooner.
