BREAKING CHANGE - objects with "train" in the name (sp.classtrain, sp.clustertrain, sp.setuptrain~) have been renamed to be more consistent with other objects (sp.classcreate, sp.clustercreate, sp.setupcreate~)
BREAKING CHANGE - sensitivity parameter in all onset-based objects has been fine-tuned to work across a wider range of instruments and materials so your previous settings may likely need adjusting
BREAKING CHANGE - threshold parameter renamed to floor in all onset-based objects (sp.onset~, sp.onsetframe, sp.descriptors~, sp.melbands~, sp.mfcc~, sp.sines~, etc...)
BREAKING CHANGE - threshold parameter renamed to sensitivity in sp.novelty~ keeping it inline with other onset detection objects macro controls (sp.onset~, sp.spectralonset~)
BREAKING CHANGE - mode parameter renamed to timestretchmode in sample playback objects keeping to remove clash with the new mode attribute
BREAKING CHANGE - input mode order and modes changed on all onset-based object (sp.onsetframe, sp.descriptors~, sp.melbands~, sp.mfcc~, sp.sines~, etc...)
BREAKING CHANGE - clusters trained with sp.clustertrain now count from 1 instead of 0 and are returned as ints instead of a symbols (so a 1 instead of a "1")
BREAKING CHANGE - sp.classifierdisplay@drum attribute reworked to @defaultdisplay
BREAKING CHANGE - fade in/out and curve parameters renamed in sp.corpusplayer~ to be consistent with the new sp.sampler~ (attack=in, hold=out(and inverted), attackcurve=incurve, holdcurve=outcurve)
overview patch (SP-Tools Overview.maxpat) completely revamped with better discoverability and package navigation
added snippets for common use cases to SP-Tools package (accessible via the snippets side panel)
restructured Max Package folders to make it easier to navigate and add additional corpora
restructured github repo to separate versions (Max, pd), Max for Live devices, and additional corpora
added class-combined versions of all descriptor analysis objects making it easier to get classification combined with descriptor analysis (sp.classdescriptors~, sp.classmfccs~, etc...)
added sp.controllermatch to browse corpora using a single parameter
added sp.controllerptich to create pitch-quantized melodic phrases from a single parameter
added zero-latency convolution (sp.convolver~) which allows for reverb, amp sim, mic correction, and any other convolution-based audio processes
added convolution-based corpus matching via sp.corpusconvolver~ which combines corpus matching and realtime convolution
added combined abstractions for common processes (sp.corpusanalysis~, sp.corpussampler~)
added radius and neighbor selection in concat matching
added pitch and loudness compensation to concat playback
added transpose and pretranspose to concat playback
added sp.corpusclustermatch for creating clusters from corpora, allowing for grouping of similar sounds within a corpus (e.g. kick, snare, hat, etc...)
added objects for shaping and processing descriptor lists (sp.descriptorcurves, sp.descriptorreplace)
added an envelope follower with some quirky features (sp.envelope~)
added sp.gridscale for scaling and shifting XY-based controller inputs (combines well with sp.gridmatch and the new sp.boppad)
added pitch and time quantization with sp.quantizepitch and sp.quantizetime~
added data and clock sequencers with sp.sequenceclock~ and sp.sequencedata~
added Schmitt filter for descriptor filtering for when you need hysterisis in the filtering (sp.schmitt)
added various audio processes for splitting and decomposing signals (sp.scatter~, sp.scramble~, sp.shatter~, sp.shattercreate~, sp.sift~, sp.smear)
added new kitchensink descriptor type, as a combination of descriptor/melband/MFCC buffers which comes in onset, real-time, and class-based variants (sp.kitchensink~, sp.kitchensinkrt~, sp.classkitchensink~)
added neural network classifier type to sp.classtrain, sp.clustertrain, and sp.classmatch for greatly improved speed and accuracy
added support for the BopPad controller (sp.boppad)
added input modes to all the physical modeling objects (sp.karplus~, sp.resonators~, sp.shaker~, sp.waveguidemesh~) allowing for realtime actuation of the models, in addition to onset/trigger-based actuation
added ability to reverse and loop samples, and jump directly to sample position in sp.corpusplayer~
added @mode attribute to sp.onsetframe~ to switch between amplitude and spectral onset detection (also impacts all onset-based descriptors objects (sp.descriptors~, sp.melbands~, sp.mfcc~, sp.sines~, etc...))
added ability to seed clusters in sp.clustertrain
added utility for subdividing a spaces of arbitrary size and steps (sp.slicecurve)
added utility for time-alining trigger/gates with descriptor output (sp.triggeralign~)
added utility for increasing the length of triggers and gates (sp.triggerlength~)
added AHR-style envelope with sp.triggershape~
improved time-alignment for trigger/gate outputs of descriptors objects (sp.descriptors~, sp.melbands~, sp.mfcc~, sp.sines~, etc...)
reworked sp.classifierdisplay to automatically load class names from all class matching objects
reworked sp.descriptordisplay to automatically display the correct type of descriptor
added dump output message to all class-based objects (sp.classmatch, sp.classdescriptors, etc...)
added mic correction (via a new input mode attribute @input 5) to all onset-based descriptor analysis objects for better descriptor results when using only an SP sensor
added @buffer attribute to sp.corpusplayer~ to simplify non corpus-based sample playback
added @history attributes to all realtime descriptor objects (sp.descriptorsrt~, sp.melbandsrt~, sp.mfccrt~, sp.sinesrt~) to smooth descriptors
added @input modes to sp.onset~ allowing for optional filters optimized for different input types
added onthreshold and offthreshold to sp.novelty~ given you finer grain control of thresholding
improved (and fixed) melband transposition in sp.datatranspose
added optional arguments to all corpus matching abstractions to load corpus and setups automatically (e.g. sp.corpusmatch corpus_china setup_snare will automatically load the China Cymbal corpus and load/enable the snare setup)
added ability to load default files to all.json loading objects (e.g. sp.resonators~ resonators_bell)
added header to every .json file to differentiate them (you should reanalyze all your corpora, classes, and setups)
when loading a setup into any corpus matching abstraction (sp.corpusmatch, sp.corpusconvolver~, sp.corpussampler~) it will automatically enable that setup
improved default starting values in sp.controllers so it gives useful results while it autocalibrates
added ability to trigger sp.triggerbounce~ and sp.triggercloud~ with bangs as well as trigger/gates
added ability to trigger synthesis objects (sp.lpg~, sp.karplus~, sp.resonators~, sp.waveguidemesh~) with bangs as well as triggers/gates
added 8 more abstractions to the puredata version
changed FFT settings for medium and all sizes for corpus and setup analysis to have better pitch accuracy in the larger time scales. You should re-analyze all your own corpora and setups.
you can now load mp3 files into sp.corpuscreate
fixed M4L device loading bug(s)
abstractions that only function as part of an existing abstraction (sp.lpgcore~, sp.folderloop, etc...) have had their sp. prefix replaced with widget and have had their help/reference pages removed
