xsample - extended sample objects for Max/MSP and pd (pure data)
Copyright (c) 2001-2003 Thomas Grill (xovo@gmx.net)
For information on usage and redistribution, and for a DISCLAIMER OF ALL
WARRANTIES, see the file, "license.txt," in this distribution.
Donations for further development of the package are highly appreciated.
----------------------------------------------------------------------------
IMPORTANT INFORMATION for all MaxMSP users:
1) For OSX it is best to put the xsample file somewhere in your Max/MSP search path and drop the file
xsample-objectmappings.txt into the folder /Library/Application Support/Cycling '74/init .
2) Otherwise (or for OS9) it is advisable to put the xsample shared library file into the "max-startup" folder.
Hence it will be loaded at Max startup.
3) If you want to load the xsample library on demand, create a [xsample] object in Max/MSP.
----------------------------------------------------------------------------
You will need the flext C++ layer for PD and Max/MSP externals to compile this.
see http://www.parasitaere-kapazitaeten.net/ext
Package files:
- readme.txt: this one
- gpl.txt,license.txt: GPL license stuff
- main.h,main.cpp,inter.cpp,inter.ci: base class definition for all the other objects
- record.cpp: xrecord~
- play.cpp: xplay~
- groove.cpp: xgroove~
----------------------------------------------------------------------------
BUILDING XSAMPLE
----------------
The package should at least compile (and is tested) with the following compilers:
pd - Windows:
-------------
o Microsoft Visual C++ 6 command line: edit "config-pd-msvc.txt" and run "build-pd-msvc.bat"
o Microsoft Visual C++ 6 IDE: edit "xsample.dsp" project file
> due to a compiler bug the optimization using templates is not functional
o BCC: edit "config-pd-bcc.txt" and run "build-pd-bcc.bat"
o Cygwin GCC: edit "config-pd-cygwin.txt" and run "sh ./build-pd-cygwin.sh"
> various versions of GCC die during compile with template optimization turned on
pd - linux:
-----------
o GCC: edit "config-pd-linux.txt" and run "sh ./build-pd-linux.sh"
> various versions of GCC die during compile with template optimization turned on
pd - OSX:
-----------
o GCC: edit "config-pd-darwin.txt" and run "sh ./build-pd-darwin.sh"
> various versions of GCC die during compile with template optimization turned on
Max/MSP - MacOS9:
----------------
o Metrowerks CodeWarrior: edit "xsample.cw" project file functions
o Apple MPW-PR: edit & use the "flext.mpw" makefile
Max/MSP - MacOSX:
----------------
o Metrowerks CodeWarrior: edit "xsample.cw" project file functions
----------------------------------------------------------------------------
Goals/features of the package:
- portable and effective sample recording/playing objects for pd and Max/MSP
- MSP-like groove~ object for PD
- message- or signal-triggered recording object with mix-in capability
- avoid the various bugs of the original MSP2 objects
- multi-channel capability
- live update of respective buffer/array content
- switchable 4-point or linear interpolation for xplay~/xgroove~ object
- cross-fading loop zone (inside or outside to loop) for xgroove~
----------------------------------------------------------------------------
Version history:
0.3.0:
- added resources to MaxMSP build
- xgroove~, xrecord~: introduced a loop/end bang outlet
- added MaxMSP buffer resize recognition
- xgroove~: introduced a crossfading loop zone
- adapted source for flext 0.4.1 - most methods within class scope
- introduced attributes
- restructured make procedures
- corrected names of PD makefile, set help names
- fixed scale mode bug with xgroove~
- added validity check for buffers
- Max/MSP OSX: new file xsample-objectmappings.txt fixes load of library on finding correct helpfiles!
- makefiles for command line MSVC++, BCC, cygwin GCC
- better handling of non-existent buffers
- fixed flext-related error on setting buffers
0.2.4:
- according to flext 0.2.3 changed sample type to t_sample (S)
- xrecord~: fixed mix mode bug
- fixed argument buffer problem
0.2.3:
- using flext 0.2.2 - xsample is now a library under MaxMSP
- cleaner gcc makefile
- xgroove~, xrecord~: added "all" message to select entire buffer length
- xgroove~, xplay~: revisited dsp methods, restructured the code, fixed small interpolation bugs
- xgroove~, xplay~: added linear interpolation (message "interp 2")
- enabled 0 output channels -> xgroove~: position output only
- xgroove~: added bidirectional looping (message "loop 2")
0.2.2:
- using flext 0.2.0
- xrecord~ for PD: new flext brings better graphics update behavior
- xrecord~: recording position doesn't jump to start when recording length is reached
- fixed bug with refresh message (min/max reset)
- xgroove~: position (by pos message) isn't sample rounded anymore
- reset/refresh messages readjust dsp routines to current buffer format (e.g. channel count)
- corrected Max/MSP assist method for multi-channel
- fixed xplay~ help method
- changed syntax to x*~ [channels=1] [buffer] for future enhancements (MaxMSP only, warning for old syntax)
- fixed small bug concerning startup position in xgroove~ and xrecord~
- fixed deadly bug in xplay~ dsp code (only active with template optimization)
0.2.1:
- no leftmost float inlet for position setting - use pos method
- changed dsp handling for flext 0.1.1 conformance
- workarounds for buggy/incomplete compilers
- prevent buffer warning message at patcher load (wait for loadbang)
- fixed bug: current pos is reset when changing min or max points
0.2.0:
- first version for flext
---------------------------------------------------------------------------
TODO list:
general:
- do a smooth (line~) mixin in xrecord~ help patch
features:
- multi-buffer handling (aka multi-channel for pd)
- vasp handling
- performance comparison to respective PD/Max objects
- anti-alias filter? (possible?)
- delay min/max changes when cur pos in cross-fade zone
tests:
- reconsider startup sequence of set buffer,set units,set sclmode,set pos/min/max
bugs:
- PD: problems with timed buffer redrawing (takes a lot of cpu time) - flext bug?
- Apple MPW doesn't correctly compile template optimization
- Max help files aren't correctly opened due to xsample objects residing in a library (FIXED for OSX!!!)
