Csound full changelog

A number of bug fixes and enhancements, but also potentially
significant changes are included.
For live coders the orchestra macros are now remembered between calls
to compilerstr. This should not change the behaviour of current valid
orchestras but could be useful in live coding.
MIDI devices now include mapping multiple devices to higher channels.
The details are in the manual MIDI section.

Many changes including the removal of vst2cs functionality due to a copyright issue.
The changes made in 6.11 to raw format reading have been modified so gen1 and diskin ignore positive file formats and use the file header,
unless the format is negative when it uses the absolute value in a raw audio file. This should preserve most compatibility issues.
There are a number of new and improved opcodes, new facilities in scores and many bug fixes.

printks2: Prints a new value every time a control variable changes using a printf() style syntax.
mp3sr mp3bitrate and mp3nchnls to get information on mp3 files

USER-LEVEL CHANGES:
New opcodes:

mp3sr mp3bitrate and mp3nchnls to get information on mp3 files
EXPERIMENTAL: CUDA opcodes for partitioned convolution direct convolution and sliding phase vocoding; OpenCL opcode for additive synthesis
compilecsd to compile instruments from a standard CSD file
New Gen and Macros:
Orchestra:
The argument for i() is supposed to be a variable not an expression. This is now enforced. (bug #90)
Score:
New score opcode y sets the random seed (for ~) at read time
Options:
This was a bug in CsOptions; the last argument was missed being read (issue #296)
As command-line options expression-opt and no-expression-opt do nothing in Csound6 a warning is printed.
Modified Opcodes and Gens:
For ogg output it is possible to specify a VBR (variable bit rate) quality.
dssi4cs code has been extensively reworked to avoid potential memory faults.

USER-LEVEL CHANGES:
New opcodes:
instance opcode schedules a new instrument instance, storing the instance handle
kill opcode stops a given instrument instance
strfromurl to set a string from a URL
New Gen and Macros: None
Orchestra:
If building supports it, a #include string can be a URL or a file
A space is again permitted between a function name and the opening bracket for all functions allowed in Csound5 (but not in general)
The Csound command can start with an empty CSD in daemon mode
(daemon daemon mode: do not exit if CSD/orchestra is not given, is empty or does not compile)
Score:
If building supports it, a #include string can be a URL or a file
Modified Opcodes and Gens:
Many filters generalised to allow k- or a-rate parameters. In particular it includes these: areson, atonex, butterworth filters, fofilter, lowres, lowresx, lpf18, mode, moogladder, moogvcf, reson, resonr, resonx, resonz, statevar, tonex

· Many bug fixes and code improvements
· New opcodes: faustgen, array
· Added 0dbfs and nchnls override
· Added delete tree to the API
· Greatly improve array arithmetic operations
· Removed limit on number of instances in parallel code
· Fixed schedwhen for named instrs
