each channel

saving a "large" AMOS Sample Bank would "sometimes" cause a delayed crash

tests/ST-01.cat fixed DigiHarp, Heaven, RoomBrass, SlapBass, String6 and
Touch to the best (not truncated, faded out, octaved up or echoed) versions
from a discussion on https://eab.abime.net/showthread.php?t=81432 - in the

4 channel and mix mode are now close to perfect, also improved timing
precision on the NOTEs when _RENDERing

sequencer upgraded by using a memory bank and string builder instead of AMOS
strings reducing memory requirements, Set Buffer set back to 50k from 160k

powerpacker.library upgraded, 68000 compatible version 36.10
https://aminet.net/package/util/libs/pplib16 for backward compatibility

file requester new right click menu File List >> Refresh - list sorting

Process >> Effects >> Reverb now has variable feedback and uses dials

Process >> Effects >> Simple Echo retired (circa. 1991), change
Edit >> Frame >> Time Division and use the simple echo.asc macro instead

Process >> Effects >> Tremolo updated

other updates for various reasons


bug fixes
---------
updated the octamed block selection as modules start at block 0, not block 1

finetune discrepancy discovered with the octamed to sequence subroutine

the first note on the first track of a block in an octamed module was not
being rendered due to corruption

SEQ command without a parameter would overflow the direct mode paging system
making it difficult to debug a sequence

previewing the realtime fx on all 4 channels with Caps Lock would jump back
to 1 channel while using Shift on a dial

Process >> Distort >> Alias had extra noise created during its realtime
preview that wasn't in the processed result

Process >> Distort >> Fold slider was logically backwards

windy.asc macro renamed to shimmer.asc, also updated as it broke the ability
to undo

mute with the dial now won't insist on changing if you attempted to
increase/decrease past the limits without actually changing anything

a typo uncrunching powerpacked files caused the file requester to be in the
wrong folder, and File >> Revert was broken

Process >> Bitwise >> Logical shift left is retired, "in the case of a left
shift, arithmetic and logic shift do the same operation"

_TGLCONTROLS did not preserve the highlights on the dials for mute or amihz,
it would also reload the settings from disk

fixes to range selection, shift for chunky no longer skips positions,
flipping over to the other side now shows the correct range positions in the
header and if playing the loop is updated as you move, cancel with esc is
improved

other fixes for various reasons


-----------------------------------------------------------------------------

Version 1.22

new features
------------
accelerated graphics now standardized with FBlit (see wiki)
https://aminet.net/package/util/boot/fblit

Mute function by clicking the Volume Dial and Tab shortcut key that in multi
track toggles the current channel and highlights the view

Utils >> Controls toggles the controls at the bottom, for a larger view of
the waveforms

CALC <bank number> command to set the current waveforms resampling ratio for
_RESAMPLE from the waveform in <bank number>

OFFSET <bank number> command to set the current waveforms playing offset from
what is playing in <bank number>

programmable keyboard shortcuts set with commands: SHIFT, CTRL, AMIGA and ALT
e.g. for Control Escape: CTRL 69 FLSHSCR,QUIT,

added autoexec.asc macro that doesn't show in the menu but is executed just
after startup


updates
-------
Options >> Debug now also shows the character code for each key press

Utilities >> Piano >> Portamento piano mode just changes the FREQ of the
current playback

changed the direct mode screen to show at the top of the screen and is also
draggable by its bottom

removed the waveform redraw limit for running sequences with accelerated
graphics

the screen is NOW reset to Pal or Ntsc when using 50Hz/60Hz in the Options

_STOP no longer happens when loading a file while playing that needs
conversion, it is muted during the process new macros rewind.asc and
windy.asc added

Help >> Topics updated

other improvements and updates for various reasons


bug fixes
---------
error fixed with Edit >> Frame Beat Left/Right if the range selected is
smaller than a time division

the new MUTE system exposed an obscure bug with the gui that only occurred
while running sequences, effects and mouse actions concurrently

opening a stereo/quad file in multi mode incorrectly set _CHANNELS as more
than 1, which could affect how an IFF CAT was then created, breaking the
header and seemingly truncating the files - OPENASRAW can recover the data

better recovery when loading multi-file formats if a low memory failure
occurs

increased file header buffer size and improved error recovery when loading

not all subroutines were showing in Help >> Topics >> Subroutines

OPEN in direct mode returned to the direct mode screen too early

refactored legacy BGPLYING state variable

regression - random pop up messages after opening files

regression - it should not zoom out after processing a range

regression - pasting while zoomed in should not zoom out

other fixes and optimizations for various reasons

-----------------------------------------------------------------------------

Version 1.21

new features
------------
optional Windowed-Sinc interpolation implemented for resampling 
Help >> Options >> Interpolation

improved quality in the floating point routines and tone generators

new 14bit macros - 32bit to 14bit, 24bit to 14bit and 16bit to 14bit
use Open As Raw, then use the macros

shift Play All now acts as an unpause/restart function

Process >> Decode >> Deinterleave 24bit

Process >> Convert >> 16bit Flip - flips the byte order of a 16bit waveform

Process >> Filter >> Limit Noise - works like Contract but only on the lowest
dither level


updates
-------
transpose and finetune for octamed modules is now working

FINE= command to set the finetune (-8 to +7) for the next NOTE= command

NOTE= command expanded to allow note number or note name
NOTE=60 does the same as NOTE=C-6

the calculator fits underneath the oscilloscope and has an exit button

file requester support for gigabyte sized files

new saved files and recordings will appear in the file list sorted to the
correct position without a cache refresh

folder selection waits for mouse up and clicking can be cancelled by moving
off the item

mouse sets the position of the text cursor when editing the filename

the behaviour for using Range while Range Play is active has changed - it now
sets the range after mouse up instead of instantly on mouse down, also the
action can be cancelled by pressing the escape key before releasing the mouse

when opening in multi mode only position 1 will set the main frequency, other
modes always set the main frequency

other optimizations and edits for various reasons


bug fixes
---------
Process >> Resample >> By Rate had the from and to frequencies logically the
wrong way around

Repeat now works for the Resample subroutines without reopening their windows
 
the floppy distribution's powerpacker library was not compatible with 68000
for a500

the previous version source code, not the current version was included in the
lha distribution

removed need for _COPYSWAP _WORKSWAP in macros - demo2, triangular and
sawtooth macros updated

under some circumstances saving a stereo or quad iff had missing channels

***some 16SV files have a HI_LENGTH of half of what it should be, the BODY
size is used instead

opening octamed files will no longer purge the file list cache

fixed an interaction in the file requester when editing the text filename
then using other buttons

_REVERB and _PHASE can now be safely used in macros and sequences

_OPENASRAW no longer _STOPs and sets the mode to mono if the waveform is
loaded out-of-view

quad to multi macro updated to _NEW any existing waveforms in position 2, 3
and 4

other fixes and improvements for various reasons

-----------------------------------------------------------------------------

Version 1.20

new features
------------

Library opening is now delayed until first use

_PLAYALL is now just _PLAY

_ERASE is now just _NEW

Resize renamed back to Size as it didn't "look" right

other source code updates and optimizations for various reasons


bug fixes
---------
Size by Time had problems parsing some time values only in the compiled
version

calculator now works when an fx window is open

_REWIND made the metronome go out of sync

a sequencer optimization means a500 can now play Demo1, but has a delayed
start

Demo2 seems to lockup on a500 and a1200 but can be stopped by holding the
spacebar

highlighting the time divisions sometimes had corruption with the colours

sequences no longer skip when using the scrolling macros menu

_OCTAVEUP and _OCTAVEDOWN now stay "in time" again after use

after a shift click Play Range to turn it off, the range was broken and
couldn't restart Range Play

failed _OPTIONS no longer exit the _OPTIONS window

various other bug fixes

-----------------------------------------------------------------------------

patch running, see wiki

with range play, repositioning the single line play marker only worked when
loop was turned on

Edit >> Size didn't work in stereo or quad

the previous fudgy menu fix was incorrect, it created a problem with the
File >> sub menus, now resolved correctly

Show Range wasn't full screen on the left side

amos bank and octamed module loading now sets the meta NAME from the filename

meta data now cleared from memory using File >> New and Memory >> Erase All

with octamed modules not all 16 bit samples were converted automaticaly if
in multi track with a selected range !#$%

under some circumstances, running the command sequencer would cause errors
when using the menus

the tone generator window would also error if a certain type of sequence was
running

many TOAST notifications for subroutines were dependent on a previous
positive setting from an Ok button

-----------------------------------------------------------------------------

Version 1.18 (first aminet release)

new features
------------
File >> Save As >> Iff

File >> Save All >> Iff CAT concatenated iff file

new issue created in 1.17 fixed where the sample name and sizes in the header
were the previously selected details

_NOTEUP and _NOTEDOWN finished showing an incorrect frequency, the actual
frequency was correct

progress bar was left hanging at the end if running the subroutine from
direct mode

macros that used _COPY without a range left the full range selected after
completion

the filename in the header was not updated if a macro created a new "Unnamed"
filename

range select just a single line failed when the file was very big, selecting
a small chunk

if the time became over 99 hours due to very low frequency on very big files
the mix loop button graphic was corrupted

lag in the oscilloscope fixed

Piano would always switch to Range Play even if Display Play was active

switching to and from mode 4 with some empty banks carried over some
repeating distortion
