add sound effects

[truj]

Something more or less like this:
channel effect:what/function duration options
E.g. for a pitch band change affecting the whole channel:
0 effect:pitchband/sinus /2 amplitude=20, wavecount=2.5
Or for a polyphonic aftertouch graph affecting only one note:
0 effect:polypressure/line /2 from=-5, to=15, note=c+

Most (but not all) sound effects will be MIDI controller changes.
Not always a function is required. Some controllers don't even support more values than true or false.
So here's a new idea:

Function (lowlevel syntax):

0 volume.sin(ampl=50;periods=5.3) *1

Function (compact syntax):

0: (volume.sin(ampl=50;periods=5.3;length=1))

Simple setting (lowlevel syntax):

0 volume.set=75 -

Simple setting (compact syntax):

0: (volume.set=75)

Not sure yet, if lowlevel syntax should be supported for this at all.

Again a new idea - Pipelining:

Lowlevel:

0  bend.wait().line(64,127).wait().length(/2).line(127,64)  /4
0  c  /1+/1

Compact:
0: bend.wait().line(64,127).wait().length(/2).line(127,64) c:1+1

Meaning:

• A C is played for two whole notes.
• wait(): It stays unchanged for a quarter note
  • quarter because /4 in lowlevel and default in compact
• line(64,127): The next quarter it is pitch-bended from the middle to maximum
  • pitch-bend because the first bend determines the effect
• wait(): It stays at maximum for a quarter note
• length(/2): sets the length to a half note for following pipeline functions
• line(127,64): during the next half note the bend is reduced from maximum to the middle again
• the rest of the note is untouched

I think this is better then the option-like syntax (any.thing(value)). There are too many braces.

Also another idea for setters and binary controllers: These can also be implemented as functions, just like line() or sin():
0: hold.on() c d e hold.off() c d e volume.set(127) c d e volume.set(30%) c d e

A possibility to address controllers or RPNs by number:
ctrl=7.sin(20,60,4.3)
rpn=0.set(6)
This addresses controller 7 (volume) or RPN 0 (pitch bend sensitivity)

[truj]

Maybe pipelining is the wrong wording. Such a call chain should be renamed to effect flow (or maybe 'chaining'?). This also applies for the class, variables and placeholders.

Not to be forgotten:

• call closeFlowIfPossible() from the parser
• poly_at / mono_at (special treatment)
• pitch bend (special treatment with a parameter for half-tone-steps - connected to pitch bend range)
• nestable blocks and functions - make sure it works there as well
• patterns !!! - very important. Special treatment for aftertouch notes (support indices)
