For Windows put the xsample file somewhere in your Max/MSP search path and drop the file xsample-objectmappings-win.txt in C:\program files\common files\Cycling '74\init (english version) or C:\Programme\Gemeinsame Dateien\Cycling '74\init (german version) 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, use the "install" option of the Max file menu and point it to the xsample file or create a [xsample] object in Max/MSP. ---------------------------------------------------------------------------- IMPORTANT INFORMATION for all PD users: xsample is a library containing several external objects. You should load it at PD startup by adding "-lib xsample" to the PD command line. (If you forgot to do that, you can load the library by creating an [xsample] dummy object. ---------------------------------------------------------------------------- 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 crossfading loop zones - 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!!!)
