Re: [PD] looking for a simple eq
ELSE has many filters and the tutorial it comes with shows you how to build multiband equalizers.

Hi, i recently made a "channel_gui" abstraction for a patch on the RPI, using vanilla filters and the object [equaliser] from the GGEE library (you will need to install that first with deken) it has a lowpass, a highpass, and one parametric EQ like filter (made with [equaliser], which basically calculates the right coefficients for the vanilla [biquad~] object) i attach it here, you will have to remove some stuff and tweak it for your needs, but it's not too complicated. plus you can control output volume and add a delay (if needed) best oliver #N canvas 386 128 885 527 12; #X obj 221 48 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X obj 212 66 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X obj 588 23 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X obj 588 43 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X obj 227 96 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X obj 220 155 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X obj 161 21 cnv 10 88 148 \$0-bgnd \$0-bgnd-r 1 75 10 1 18 -249661 -159808 0; #X obj 160 155 nbx 5 15 0 200 0 0 \$1-v \$1-v-r vol 60 8 1 12 -262110 -1 -1 100 256; #X obj 160 20 nbx 3 15 0 44100 0 0 \$1-d \$1-d-r del 45 9 1 12 -203904 -1 -1 0 256; #X obj 291 393 *~; #X obj 291 348 biquad~; #X obj 327 319 equalizer 2 0 8, f 20; #X obj 160 100 nbx 5 15 20 24000 1 0 \$1-f \$1-f-r freq 60 8 1 12 -204786 -1 -1 2 256; #X obj 160 115 nbx 5 15 0 10 0 0 \$1-q \$1-q-r q 60 8 1 12 -204786 -1 -1 0 256; #X obj 160 130 nbx 5 15 -80 80 0 0 \$1-g \$1-g-r gain 60 8 1 12 -204786 -1 -1 0 256; #X obj 327 289 t b f; #X obj 373 289 t b f; #X obj 291 421 dac~ \$1; #X obj 297 19 loadbang; #X obj 381 48 delwrite~ \$0-d 1000, f 10; #X obj 292 118 delread~ \$0-d 0, f 17; #X obj 382 19 catch~ \$1-out; #X obj 638 45 del 100; #X obj 638 70 \$1; #X msg 532 263 symbol kiste_dfv; #X obj 532 288 text search kiste_args; #X obj 532 314 +, f 5; #X obj 532 341 text get kiste_args; #X obj 357 348 * 0.01; #X obj 357 373 pow 2; #X floatatom 357 400 5 0 0 0 - - -; #X msg 125 152 100; #X obj 64 375 text set kiste_args; #X obj 16 345 spigot; #X obj 741 122 s \$0-spig; #X obj 88 345 r \$0-spig; #X msg 741 96 0; #X obj 638 123 del 100; #X msg 638 148 1; #X obj 67 345 tgl 15 0 empty empty empty 17 7 0 10 -262144 -1 -1 1 1; #X obj 26 62 t b f; #X obj 16 35 t f; #X obj 36 94 t b f; #X obj 16 375 t b l; #X obj 16 402 s writeargs; #X obj 54 125 t b f; #X text 390 151 Alle GUIs haben #1 am Anfang, f 9; #X msg 297 44 bang; #X obj 494 72 makefilename %d; #X obj 494 45 \$1; #X msg 494 97 label \$1; #X obj 494 122 s \$0-bgnd-r; #X obj 297 69 s \$0-init; #X obj 638 19 r \$0-init; #X obj 494 19 r \$0-init; #X obj 700 306 r \$0-init; #X obj 291 198 lop~; #X obj 292 145 hip~; #X obj 292 172 demux~; #X obj 290 222 demux~; #X obj 344 179 hip~; #X obj 328 248 lop~; #X obj 160 47 nbx 5 15 20 2 1 0 \$1-hp \$1-hp-r hp 60 8 1 12 -232576 -1 -1 20 256; #X obj 160 62 nbx 5 15 20 24000 1 0 \$1-lp \$1-lp-r lp 60 8 1 12 -232576 -1 -1 2 256; #X obj 160 77 tgl 13 0 \$1-oct \$1-oct-r -6db/-12db 20 8 1 11 -232576 -1 -1 1 1; #X msg 700 333 0 20 2 1 2 0 0 100, f 14; #X obj 532 489 s \$1-d-r; #X obj 553 465 s \$1-hp-r; #X obj 575 441 s \$1-lp-r; #X obj 596 418 s \$1-oct-r; #X obj 618 394 s \$1-f-r; #X obj 639 489 s \$1-q-r; #X obj 661 465 s \$1-g-r; #X obj 683 441 s \$1-v-r; #X obj 73 164 t b f; #X obj 92 196 t b f; #X obj 112 226 t b f; #X obj 132 257 t b f; #X obj 16 315 pack 0 0 0 0 0 0 0 0; #X obj 532 368 unpack 0 0 0 0 0 0 0 0; #X msg 109 39 20; #X msg 109 59 24000; #X msg 109 98 24000; #X obj 480 186 r kiste_get_dfv_from; #X obj 532 236 t b f; #X obj 480 211 + 1; #X obj 480 236 sel \$1; #X floatatom 578 235 5 0 0 0 - - -; #X msg 690 153 symbol kiste_dfv; #X obj 690 178 text search kiste_args; #X floatatom 690 228 5 0 0 0 - - -; #X obj 690 203 +; #X obj 638 97 t b f f b f b; #X connect 0 0 80 0; #X connect 1 0 81 0; #X connect 4 0 82 0; #X connect 5 0 31 0; #X connect 7 0 28 0; #X connect 7 0 77 0; #X connect 8 0 20 0; #X connect 8 0 41 0; #X connect 9 0 17 0; #X connect 10 0 9 0; #X connect 11 0 10 0; #X connect 12 0 11 0; #X connect 12 0 74 0; #X connect 13 0 16 0; #X connect 13 0 75 0; #X connect 14 0 15 0; #X connect 14 0 76 0; #X connect 15 0 11 0; #X connect 15 1 11 1; #X connect 16 0 11 0; #X connect 16 1 11 2; #X connect 18 0 47 0; #X connect 20 0 57 0; #X connect 21 0 19 0; #X connect 22 0 23 0; #X connect 23 0 92 0; #X connect 24 0 25 0; #X connect 25 0 26 0; #X connect 26 0 27 0; #X connect 27 0 79 0; #X connect 28 0 29 0; #X connect 29 0 9 1; #X connect 29 0 30 0; #X connect 31 0 7 0; #X connect 33 0 43 0; #X connect 35 0 39 0; #X connect 36 0 34 0; #X connect 37 0 38 0; #X connect 38 0 34 0; #X connect 39 0 33 1; #X connect 40 0 78 0; #X connect 40 1 78 1; #X connect 41 0 78 0; #X

Hey Christof, Yes, the patch is indeed running on a raspberry pi:-) (should have mentioned that) Best, Jakob Gesendet: Mittwoch, 28.

Use the right tool for the job!

Re: [PD] looking for a simple eq
(re-posting to the actual mail list) The simplest way would be to use vstplugin~ and just use a vst plugin you are used to. Deken should include it. Go "Help" -> "Find Externals" and search for "vstplugin~" (don't forget the "~") Might be not all plugins work as expected (at least on Linux), but I've used it on live stuff and it has worked pretty well for me.
