lots of malloc()s and very few free()s
clean up

• sequences
• whammy messages
• static cc messages
  ...and various other places

a counter with 4 steps, and reset_to 1 will count like this:
0 - 1 - 2 - 3 -1 - 2 - 3 - 1 - 2 - 3 ....

Nice for bass lines

the touch strip should be configurable as an overtone (or any tone) tapping area
overtones are defined for each chord/sequence step

probably implementable by adding a message type for specific values, and including a note on option (+ a separate note_t variable for overtones)

the user should be able to list multiple patches from the command line, and to switch between them with some button combination

./louwiigui patch1.xml patch2.xml patch3.xml

when playing chords:

• other chord_states (colored button combinations) trigger new notes, replacing notes in the chord
• return to original chord when the extra buttons are released/repressed

Probably easy to implement by reuse of the string idea from sequences

• each replaceable note is given a string number
• triggering a note with a string number will send note off for the previous note with the same string number before note on for the triggered note

3 chord sets per program/bank:
why: handy for different chords/voicings in verse/chorus/bridge
how: selectable with buttons 1, 2 and 1&2 (=3)

This will allow two step sequences, like alternating bass and chord, or alternating bass and bass + chord.
Used in sequences, it can be used to play two different sequences, depending on the direction of the first strum. (or multiple different sequences for more complex strumming patterns than up-down-up-down)

on patch changes
and bank changes

LouWiiGui should read program_number attributes from patch and bank, and send MIDI program change messages when the patch is loaded or the bank is selected

Let wonderful things happen when the accelerometer detects sudden upwards movement (like we are used to from Guitar Hero)!!!

pause sequencers

• switch from midi tempo to cv tempo
• let the strummer somehow send sync pulses
  = guitarist controlled tempo (= superstar superpower)

all memory allocated with malloc() shold be freed with free()

Playing a note with the following configuration:

if a note is active on string 2, should result in:

cc message: legato on
note on message: new note
note off message: old note on string 2
cc message legato off

simulate guitar finger picking:

• let button combinations be assigned to sequences of chords
• every strummer action plays the next chord in the sequence, in loop
• notes can have a sustain attribute, which let the note sustain until the same note is struck again, or until the next change of chord (or sequence)

• button: transpose up

• button: transpose down
  (- is at the top when the wiimote is in the guitar controller)
  home-button returns to untransposed notes/chords

It is time to upgrade the joystick to be as configurable as the whammy and touch bar.

Type: bug
Severity: critical (in the context of bugs in a Wii guitar to midi program...)
Causes the program to crash.

how to reproduce:

• load testIn.xml
• select bank 2
• press and hold red, yellow and blue buttons
• press and hold the strummer
• release the yellow button

so neck action while playing a chord will sometimes cause a segmentation fault

adjust sound parameters to specific chords/sequences

switch legato/portamento/sustain on before a sequence, and off when the sequence is deactivated

• before notes on
• after notes on
• before notes off

support for midi sequencer start/stop/continue would be nice...
