[CW] cwpt2/LCWO users: enhanced feature for mixed plain text and code groups practice text

[Bill Lanahan]

cwpt2.exe (pse replace cwpt with cwpt2 and get new readme file)

Below is the text from the readme on this capability. Its a lot of words
for something that's easy to try.
Lets you have higher speed for the plain text, than the interspersed code
groups, also has some other perks.

This link   qsl.net/wa2nfn/cw.mp3    is a demo of using some of whats in
the text below added to another feature which
cycles between slow and fast intervals - briefer to listen. (like all my
examples, focus on the concept not the content; everything is configurable
(speeds, text, lengths, code groups, etc.)

Example 22:
</H2>
<B>cwpt2.exe -min=2 -max=4 -cgmin=6 -cgmax=8 -mixedMode=3</B>
<PRE>
This input file for this example is a simple list of short words. The first
line of output follows:

on at of 3,a??4 no he is a4263?/ and hat four ......
         ======          =======

NOTE: In the above, after every 3 words (mixedMose=3) we get a code group.
      We can add an option -MMR (mixed mode random) which gives a 50/50
chance that a code group will be
      suppressed to lessen predictability. (new as of 1/27/2020)

<B>cwpt2.exe -min=2 -max=4 -cgmin=6 -cgmax=8 -mixedMode=3
<mark>-MMR</mark></B>

NOTE: The stretch below with no code group due to -MMR.

on at of 3,a??4 no he is a4263?/ and hat four in and on hat he of ?.23d3 he
so .....
         ======          =======                                  ======

 *** IF YOU ARE USING LWCO/EBOOK2CW FOR PLAYBACK AND mixedMode=X, YOU CAN
ALSO USE SPEED CHANGES ***
 ***

      Typically people can copy plain text faster than they can copy
codeGroups, with this in mind you
      might want to have the copy above configured with inline speed
changes so that plain text "words"
      could be sent at a higher speed than the code groups. To achive this,
we use two more ebook options
      we've seen before; EB_LOW sets the low(slow) speed of the code group,
and EB_STEP the incremental
      speed to add to EB_LOW to get the higher speed to use for the plain
text.

<B>cwpt2.exe -min=2 -max=4 -cgmin=6 -cgmax=8 -mixedMode=3 <mark>-EB_LOW=20
-EB_STEP=5</mark></B>

|w25 two four nine |w20 fl,we0 |w25 four ten one |w20 yb251c |w25 one five
nine |w20 ajrr7h |w25
---- +++++++++++++ ---- ====== ---- ++++++++++++ ---- ====== ----
++++++++++++  ---- ====== ----

      You see the copy starts with the speed at 25 wpm, thats EB_LOW=20 +
EB_STEP=5.
      You see prior to each code group the speed drops.

      In the above generated text for LCWO (you can paste this line into
"Convert text to cw" screen)
      the inline speed changes are underlined with dashes, the plain text
(played at high speed) is underlined
      with pluses, the code groups are underlined with equals.

      Of course -MMR could also be used as previously described (not shown
again).

      As shown in example 16a, if the user desires two other options EB_SF
(slow to fast transition) and/or
      EB_FS (fast to slow) can be given a string (character(s), ProSign)
which provides an audible alert
      in morse code that the speed will transition. If used, the alert
string is sent PRIOR to the speed change.

      Just to demonstate, let EB_SF=,, and EB_FS=??

|w25 four two nine ??|w20 ha?l50 ,,|w25 nine ten five ??|w20 tof=u9 ,,|w25
six four four
                   --            --                   --            --

      Above the simple alert strings are underlined with dashes, they occur
just before the LCWO speed
      change.

      *** What might be more fun, is instead of using EB_SF and EB_FS
having some characters as an alert,
          to instead make use of another LCWO feature, that is change the
tone frequency of the code groups.
          The line below uses freqeucy changes, you can cut and paste this
into LCWO's "Convert text to CW"
          to try it. (To generate this I used -EB_FS="|f750" and
-EB_SF="|f600" the initial tone of 600 hz
          can be set in the browser of with -header="|f600".

|f600|w25 four two nine |f750|w20 ha?l50 |f600|w25 nine ten five |f750|w20
tof=u9 |f600|w25 six four four

=========               =========
600hz 25wpm            750hz 20wpm

      Or better yet! Instead of changing the tone of the code group, or
using a text alert, we can generate a short
      signal by using letter E or T framed by a short amount of silence
(200ms in this example) and just changing
      the tone of that one letter. Make EB_FS and EB_SF="|S200 |f860 E
|S200 |f680" (note spaces are required.)

      The copy is below. Start at 680 hz, play 3 words at 25 wpm, a high
pitched E framed by some silence, 2 words at
      35 wpm, and repeat the cycle until the -num XX words have been output.
