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: - 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 . . example of score: i1 0 20 244 where p4 = frequency. 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

This instrument creates a Shepard tone. See http://en.wikipedia.org/wiki/Shepard_tone for more info on what a Shepard tone is. p-fields: p4 is the pitch or frequency p5 is the amplitude BSB widgets: speed is how fast each component varies envelope shape determines when the amplitude of a component is the highest, more to the beginning or to the end; use 0.5 for regular Shepard tone pulse width is used for the vco2 opcode if the waveform is square or triangle, values are limited to the stable range speed, envelope shape, pulse width and panning have an extra text field which in the code is appended to the value of the knob; use e.g. *p6 to change the value from the score For a regular Shepard tone, use a sine wave. The other waveforms have strange artefacts, which can be nice.
