gamma> I would like to know if there is a reasonn for PMAX compile time

The main reason is that the allocation of space for each event is of
fixed size, so increasing PMAX means a general increase in memory
requirements. For some time I have wanted to relax this restriction,
but the last time I looked it seemed rather tricky. Still I might
have another look.

I would say use GEN

I think that the problem with aftouch was fixed some time ago. Can
you confirm that there is still a problem on a recent version? If so
please let me know which platform and a sample orc/sco/midifile woudl

print is an i-rate opcode so what else do you expect? If you want
repeated printings you need to use printk

I have just placed v3.52 on my servers. There are all teh PC
versions, Irix5.3, and Irix4.0 ; I hope Solaris version will follow
very soon. Macintosh 68K will be there too by now.
The main changes are opcode renamings, a few bug fixes, and a few new
opcodes. I have also attempted a first stab at the (missing) readk
opcodes.
There are teh start of some score language changes (exponential ramps
thsi time) which will allow for a more coherent language
Emacs users may care to noite that csound-orc.el has been updated to
recognise the opcode names.

Release Notes for 3.52
======================
These are the release notes for version 3.52. This is a collection of
bug fixes from 3.51, and some major opcode renaming to avoid vlashes
between variables and opcodes
Bug Fixes
---------
Extending the number of GOTOs and LABELS had two independent bugs
which wuld usually lead to a segmentation error. Fixed
Some use of [] could give a memory error, now fixed
Language Changes
----------------
aiff files with Author, Annotation and Copyright chunks read correctly
In score arithmetic, operators % (for remainder) and ^ allowed
The use of {} for exponential ramps is supplimented by ( and ). This
is so we can withdraw { and } soon so they can be used for section
brackets.
Opcode Fixes
------------
biquad has an additional optional argument to skip reinitialisation,
so smooth transitions can happen
distort1 changes so all but first argument are optional
tonex, atonex and resonx corrected when reinit is skipped. Shoudl
remove soem clicks.
The opcode readk, readk2, readk3 and readk4 have been given code. The
interpolation argument is currently ignored whiel I think about it.
The code has not been tested so may fail.
New Opcodes
-----------
poscil -- High precision oscilator
poscil3 -- High precision oscilator with cubic interpolation
lposci -- High precision looping oscilator
lposcil3 -- High precision looping oscilator with cubic interpolation
Other Changes:
-------------
opcodes islider8, islider16, islider32 renamed slider8/slider16/slider32
ilimit renamed limit
itableng renamed tableng
itimes/itimek renamed times/timek
All itable.... opcodes renamed tablei....
ictrl... renamed ctrl...
imidic... renamed midic...
ion renamed noteon
ioff rename noteoff
iout... rename outi...
kout... rename outk...
agogobel renamed gogobel
iondur renamed ondur
iondur2 renamed ondur2
is16b14 renamed s16b14
kread renamed readk
kread2 renamed readk2
kread3 renamed readk3
kread4 renamed readk4
Windows GUI Changes
-------------------
None

INITALIZATION
ift - function table number
iphs - initial phase (in samples)
PERFORMANCE
ar - output signal
kamp - amplitude
kcps - frequency
kfreqratio - multiply factor of table frequency (for example: 1 =
original frequency, 1.5 = a fifth up , .5 = an octave down)
kloop - loop point (in samples)
kend - end loop point (in samples)
poscil (precise oscillator) is the same as oscili but allows hugely more
precise frequency control (especially when using long tables and low
frequency values). It uses floating-point table indexing instead of
integer math, differently by oscil and oscili. It is only a bit
slower than oscili.
lposcil (loop oscillator) allows to vary at k-rate the starting and
ending point of a sample contained in a table. This can be useful
when reading samples loop of a wavetable which repeat speed can be
varied during the performance.
The versions with a 3 use cubic interpolation.

I believe at one time there was a fourth rate, to sit between k and i,
but as it did not seem to be useful it was removed. I think it was
called q? |
