ImagePlayer3.1

The ImagePlayer is a troublemaker; this instrument plays images. The image must in the PNG format. But still it's hard to predict what the sounding result will be, even if the 3 colors red, blue and green scanned and thus have a steady pattern as they are not moving or evolving entities in the image... A few things to understand for chosing the right image: - No sound will be produced when only black image; black is the silent canvas - 3 basic colours (RGB) on which the image opcodes react: red, blue and green. - The three colours (red, green and blue) have volume faders. - The image is scanned from left to right (X axis) and from top to bottom (Y axis) or reverse and rotated - Top of the image = the lower frequencies, bottom of the image = the higher frequencies or reverse - take a low scanning speed for adsyn, so with low base frequency, there will be no problems with Nyquist distortion (aliasing). The harmonics will be built upon the frequency set by p4 - can take a lot of CPU The lpf18 filter can be used to avoid further aliasing when experimenting at higher base frequencies . . please have a look at the Wiki page: https://github.com/kunstmusik/blue/wiki/A-Blue-instrument:-ImagePlayer version 3.1, december 2017 - rotates picture if image width is smaller then image height - replaced ADSRs by multicurve envelopes - added more envelopes - added scaling for amp, filter frequency and filter depth and pitch bend - changed AL names to more understandable ones version 3.0, december 2017 - layout converted to JavaFX standard, blue version >=2.7 - renewed layout so that: - XY controller represents the portion of the image to be scanned - added filter ADSR with depth control - added stereo option that puts RED to the left, GREEN in the middle and BLUE to the right - rescaling of base frequency when playing - more than ImagePlayer can be used in a composition - option to show image in external viewer (xviewer <file> for example). Please change according to your needs version 2.3, december 2015 - improved text for labels - added a setting for basefrequency instead of p4 - added anti-aliasing switch & aliasing filter is adjustable version 2.2, nvember 2015 - changed label 'logaritmic' to 'exponential' - XY positions are now automatable - added labels to explain the range of image to be scanned version 2.1 , november 2015 - fixed file input selector - removed fill table option because prone to errors - removed switch for inverse X Y read out (not interesting enough) - XY position for number of overtones - select log or linear ftable to hold frequencies - choose the part of the image width to play - changed filter to LPF18 with distortion - red, green and blue volume now undependent from each other version 2 , october 2015 - stereo option - add limit to voices to save CPU - variable ftable to hold frequencies - changed filter to LPF18 with distortion - switch for inverse X Y read out - ADSR - 5 basic waveforms * version 1.1, april 2013 - repaired initialization bug - show width and heigth of image - transition from raw sound (=low resolution) to clean sound (+high resolution) is fluid now - added panning * initial version 1, march 2013
