Re: [PD] Appending two signals together to create a third

So there will be a total of 9 midi controllers used (3 for each signal). i think independent control of the 3 frequencies makes this a little tricky. appending the waveform exactly at cycle-boundaries will only happen at certain frequency ratios. the best i could come up with so far was a frequency ratio and another control for the splitpoint (attached). for 1:1 or 2:1 etc. you get more or less exactly appended waves. (and changing a frequency-ratio makes quite nice sweep- or sync like sounds) i have not tried yet, but maybe it is also possible to compute the waveform with the desired nrs of b and c cycles with messages, scale the resulting table to the size of one block, and reblock the patch to fit the frequency of d. this would always guarantee exactly appended waves, though not with precise control over the frequencies of b and c. bis denn! martin #N canvas 317 118 998 883 10; #X obj 190 -35 phasor~; #X obj 46 177 wrap~; #X obj 45 198 *~ 512; #X obj 159 193 *~ 512; #X obj 159 172 wrap~; #X obj 103 598 dac~; #X obj 127 435 +~; #N canvas 0 0 450 300 (subpatch) 0; #X array \$0display 512 float 0; #X coords 0 1.5 511 -1.5 256 140 1 0 0; #X restore 285 542 graph; #X obj 287 504 tabwrite~ \$0display; #X msg 347 467 bang; #X obj 190 -63 nbx 5 14 0 1 0 1 empty empty freq_D 0 -8 0 10 -262144 -1 -1 145 256; #X obj 64 372 *~; #X obj 100 317 nbx 5 14 0 100 0 1 empty empty amp1 0 -8 0 10 -262144 -1 -1 100 256; #X obj 96 339 / 100; #X obj 222 377 *~; #X obj 258 322 nbx 5 14 0 100 0 1 empty empty amp2 0 -8 0 10 -262144 -1 -1 100 256; #X obj 254 344 / 100; #X obj 22 82 nbx 5 14 0 100 0 1 empty empty phase1 0 -8 0 10 -262144 -1 -1 1 256; #X obj 27 108 / 100; #X obj 55 155 +~; #X obj 179 106 nbx 5 14 0 100 0 1 empty empty phase2 0 -8 0 10 -262144 -1 -1 0 256; #X obj 176 124 / 100; #X obj 159 150 +~; #X obj 107 538 *~ 0.5; #X text 3 172 osc B; #X text 199 172 osc C; #X obj 522 313 table \$0waveB 515; #X obj 522 335 table \$0waveC 515; #X obj 158 217 tabread4~ \$0waveC; #X obj 39 222 tabread4~ \$0waveB; #X text 390 463 click to display wave; #X obj 593 -46 until; #X obj 593 -18 f; #X obj 624 -16 + 1; #X obj 633 153 sin; #X obj 632 130 * 6.28319; #X obj 588 41 t f f; #X obj 595 -100 loadbang; #X obj 517 142 mod 2; #X obj 527 166 * 2; #X obj 528 191 - 1; #X obj 632 104 / 512; #X obj 513 118 div 256; #X obj 625 5 mod 515; #X msg 595 -73 515; #X obj 515 228 * -1; #X obj 657 178 tabwrite \$0waveB; #X obj 509 261 tabwrite \$0waveC; #X obj 62 294 *~; #X obj 200 313 *~; #X obj 94 94 *~; #X obj 130 93 *~; #X obj 156 56 * 2; #X obj 194 56 * 2; #X obj 266 -62 nbx 3 14 1 99 0 1 empty empty empty 0 -8 0 10 -262144 -1 -1 2 256; #X obj 314 -62 nbx 3 14 1 99 0 1 empty empty empty 0 -8 0 10 -262144 -1 -1 1 256; #X text 302 -64 :; #X text 564 -123 make sine and square waves; #X text 262 -84 waveform frequency ratio; #X obj 396 51 nbx 5 14 -100 100 0 1 empty empty splitpoint 0 -8 0 10 -262144 -1 -1 0 256; #X obj 396 71 / 100; #X obj 302 113 cos~; #X obj 286 215 clip~ 0 1; #X obj 363 205 clip~ -1 0; #X obj 363 225 *~ -1; #X obj 303 142 +~; #X obj 301 62 +~ 0.75; #X obj 301 88 clip~ 1 1.75; #X obj 302 166 *~ 64; #X text 341 126 soft xfade; #X text 464 34 0-1:1; #X connect 0 0 50 0; #X connect 0 0 51 0; #X connect 0 0 66 0; #X connect 1 0 2 0; #X connect 2 0 29 0; #X connect 3 0 28 0; #X connect 4 0 3 0; #X connect 6 0 23 0; #X connect 6 0 8 0; #X connect 9 0 8 0; #X connect 10 0 0 0; #X connect 11 0 6 0; #X connect 12 0 13 0; #X connect 13 0 11 1; #X connect 14 0 6 1; #X connect 15 0 16 0; #X connect 16 0 14 1; #X connect 17 0 18 0; #X connect 18 0 19 1; #X connect 19 0 1 0; #X connect 20 0 21 0; #X connect 21 0 22 1; #X connect 22 0 4 0; #X connect 23 0 5 0; #X connect 23 0 5 1; #X connect 28 0 49 0; #X connect 29 0 48 0; #X connect 31 0 32 0; #X connect 32 0 33 0; #X connect 32 0 36 0; #X connect 33 0 43 0; #X connect 34 0 46 0; #X connect 35 0 34 0; #X connect 36 0 41 0; #X connect 36 0 42 0; #X connect 36 1 46 1; #X connect 36 1 47 1; #X connect 37 0 44 0; #X connect 38 0 39 0; #X connect 39 0 40 0; #X connect 40 0 45 0; #X connect 41 0 35 0; #X connect 42 0 38 0; #X connect 43 0 32 1; #X connect 44 0 31 0; #X connect 45 0 47 0; #X connect 48 0 11 0; #X connect 49 0 14 0; #X connect 50 0 19 0; #X connect 51 0 22 0; #X connect 52 0 50 1; #X connect 53 0 51 1; #X connect 54 0 52 0; #X connect 55 0 53 0; #X connect 59 0 60 0; #X connect 60 0 65 1; #X connect 61 0 65 0; #X connect 62 0 48 1; #X connect 63 0 64 0; #X connect 64 0 49 1; #X connect 65 0 68 0; #X connect 66 0 67 0; #X connect 67 0 61 0; #X connect 68 0 62 0; #X connect 68 0 63 0; ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

casio CZ synth, yeah? i made one of them in pd a few years ago. sounded pretty good.

[PD] Appending two signals together to create a third
Greetings All I have two signals Signal B and Signal C that I would like to append, which would create a joined signal called Signal D. I can create Signal B and Signal C but the questions I have is: I created a image that may help explain it better http://dl.dropbox.com/u/6576402/questions/flowchart_joined2.jpg 1) How do I append one signal onto the end of another. (see image labelled 2) 2) How can I vary Signal D's Frequency, Amplitude, and Phase? (See image labelled 3) I was thinking of putting a Signal B and Signal C into 1 second buffer that creates Signal D but does anyone know how to do this and if this would even work? Is PureData the program for this or is there another one that might be better suited for my task For more background I'm going to have the Frequency, Amplitude, and Phase controlled by Midi Controllers. So there will be a total of 9 midi controllers used (3 for each signal).
