# Carla TODO

# ----------------------------------------------------------------------------
# in short

4. custom "plugin slots" skins, ala Reason (also define set of keys for a new LV2 extension, 80% done)
7. direct support for csound files (as plugins, inspired by 'cabbage')

Ideas for later:

10. easier canvas connections by using smart key shortcuts
11. Mobile version (using Android Patchfield for example)
12. Mobile OSC Control app
13. Port good JACK-only apps as internal plugins (zita stuff would be nice)

# ----------------------------------------------------------------------------
# current work

FRONTEND:
 - more skins
 - testing stuff

BACKEND:
 - noexcept wherever possible

OTHER:
 - create tests for all utils code
 - fix reported bugs

# ----------------------------------------------------------------------------
# more detailed

GENERAL:
 - add direct program access on ui-dialogs (needed for standalone bridges), maybe add extra buttons too (reset plugin, fix ui size)
 - implement midi-learn (new dialog)
 - implement favorite plugins, add in new tab near file-browser
 - blender style canvas theme
 - NSM rework

FRONTEND:
 - make always-on-top depend on it^
 - complete zynfx, knob values on top
 - synth skin
 - samplers skin

ENGINE:
 - allow to change position of plugins (up/down)
 - allow to add plugins when engine is stopped
 - implement Haiku Media support (based from JACK?, LATER)
 - implement latency in continuous-rack mode
 - add MIDI-bank change type (GM, GS, XG and MMA). See fluidsynth and los docs
 ~ allow to use static OSC ports
 - switch engine modes when opening project
 - don't pass audio buffers to plugin process, make them request via ports

PLUGINS:
 - add control-out rate/freq option in frames (or just a regular block-size option?)
 - control/midi-out in singleProcess() calls, use timeoutFrames var
 - implement midi-cc automation special rules (invert, half, logarithmic, etc)
 - implement LSCP file support (new native plugin?)
 - implement Csound file support


LADSPA:

DSSI:
 - custom chunk-data extension, publish on kx website when complete

LV2:
 - revisit all extensions
 - strict bounds recheck

FluidSynth:
 - per-channel volume control
 - proper buffer-size/sample-rate change (needs testing)

LinuxSampler:
 - per-channel volume pan&control
 - proper buffer-size/sample-rate change (needs testing)

misc
-allow to open instruments via file/open menu (same as drag from left-side tree)
-allow drag of sfz/sf2/gig etc. also to patchbay (same effect as dragging to rack)
-action "remove all" in toolbar and plugin menu: add confirm dialog /!\
-action "remove folder": add confirm dialog
-add plugin macro "reset parameters"
-allow re-ordering of rack components
-setting: auto-connect to physical output when new instrument loaded (for quick audition)
-for instruments: highlight keys with assigned samples or unhighlight keys without assigned sample
-allow in-line edit window (i.e. right of rack/canvas) -> shows as soon as plugin/instr. is selected
-indicate engine at work top right
-if engine is jack, show load top right (percent and/or gauge)
-warn on quit if unsaved

patchbay
-allow click a, click b port connections
-allow multiple port selection + connection (i.e. with enter)
-allow to select connections with lasso (to delete)
