Then we made a working OF/RTcmix project! Xcode! iOS! yay!

[NOTE: I think we have now built an [rtcmix~] object that gets around the occasional crashes. I'll put a link up soon.]

Links

• Brad's ofRTcmix-iOS Xcode setup guide -- follow the instructions, and hopefully all will be well for you. This is what we did in class.
  

Class Notes and Patch Downloads

• week4-classpatches.zip -- the patches we did in class.

Here are the RTcmix scripts for the Max/MSP [rtcmix~] patches in the archive above:

klaus1.maxpatch: basic two-oscillator sawtooth sound

// WAVETABLE(outsk, dur, AMP, PITCH[, PAN, WAVETABLE])

wave = maketable("wave", 1000, "saw")

WAVETABLE(0, 0.5, 10000, 8.00, 0, wave)
WAVETABLE(0, 0.5, 10000, 8.001, 0, wave)


klaus2.maxpatch: add a MOOGVCF filter in the patch
the script is from the second [rtcmix~] object

//MOOGVCF(outsk, insk, dur, AMP, inputchan, PAN, BYPASS, FILTFREQTABLE, FILTRESONTABLE)

rtinput("AUDIO")

MOOGVCF(0, 0, 0.5, 1., 0, 0.5, 0, 400, 0.7)


klaus2a.maxpatch: use bus_config to put the MOOGVCF in the one script

// WAVETABLE(outsk, dur, AMP, PITCH[, PAN, WAVETABLE])

wave = maketable("wave", 1000, "saw")
bus_config("WAVETABLE", "aux 0 out")
bus_config("MOOGVCF", "aux 0 in", "out 0-1")


WAVETABLE(0, 0.5, 10000, 8.00, 0, wave)
WAVETABLE(0, 0.5, 10000, 8.001, 0, wave)

//MOOGVCF(outsk, insk, dur, AMP, inputchan, PAN, BYPASS, FILTFREQTABLE, FILTRESONTABLE)
MOOGVCF(0, 0, 0.5, 1, 0, 0.5, 0, 400, 0.7)


klaus3.maxpatch: add an envelope to the MOOGVCF

// WAVETABLE(outsk, dur, AMP, PITCH[, PAN, WAVETABLE])

wave = maketable("wave", 1000, "saw")
bus_config("WAVETABLE", "aux 0 out")
bus_config("MOOGVCF", "aux 0 in", "out 0-1")


WAVETABLE(0, 0.5, 10000, 8.00, 0, wave)
WAVETABLE(0, 0.5, 10000, 8.001, 0, wave)

ffreq = maketable("line", "nonorm", 1000, 0, 4000, 0.5, 100)

//MOOGVCF(outsk, insk, dur, AMP, inputchan, PAN, BYPASS, FILTFREQTABLE, FILTRESONTABLE)
MOOGVCF(0, 0, 0.5, 1, 0, 0.5, 0, ffreq, 0.7)


klaus4.maxpatch: add a secondary note following the first with a reduced filter cutoff freq

// WAVETABLE(outsk, dur, AMP, PITCH[, PAN, WAVETABLE])

wave = maketable("wave", 1000, "saw")
bus_config("WAVETABLE", "aux 0 out")
bus_config("MOOGVCF", "aux 0 in", "out 0-1")

ffreq = maketable("line", "nonorm", 1000, 0, 4000, 0.5, 100)

dur = 0.5
WAVETABLE(0, dur/2, 10000, 8.00, 0, wave)
WAVETABLE(0, dur/2, 10000, 8.001, 0, wave)

MOOGVCF(dur/2, 0, dur/2, 1, 0, 0.5, 0, ffreq/2, 0.9)


klaus5.maxpatch: add a slider to be able to control the cuttof freq interactively

// WAVETABLE(outsk, dur, AMP, PITCH[, PAN, WAVETABLE])

wave = maketable("wave", 1000, "saw")
bus_config("WAVETABLE", "aux 0 out")

ffmult = $1

dur = 0.5
WAVETABLE(0, dur/2, 10000, 8.00, 0, wave)
WAVETABLE(0, dur/2, 10000, 8.001, 0, wave)

//MOOGVCF(outsk, insk, dur, AMP, inputchan, PAN, BYPASS, FILTFREQTABLE, FILTRESONTABLE)
MOOGVCF(0, 0, dur/2, 1, 0, 0.5, 0, ffreq*ffmult, 0.9)


WAVETABLE(dur/2, dur/2, 10000, 8.00, 0, wave)
WAVETABLE(dur/2, dur/2, 10000, 8.001, 0, wave)

klaus6.maxpatch: add delay(s) to the output
the script is from the second [rtcmix~] object

// PANECHO(outsk, insk, dur, AMP, CHAN_0_DELAY, CHAN_1_DELAY, FEEDBACK, ringdowndur[, inputchan])
rtinput("AUDIO")

PANECHO(0, 0, 999, 1, 0.125, 0.5, 0.05, 1, 0)
// DELAY(outsk, insk, indur, AMP, DELAYTIME, FEEDBACK, ringdowndur[, inputchan, PAN])
//DELAY(0, 0, 999, 1, 0.5, 0.1, 1, 0, 0.5)


klaus7.maxpatch: collect scripts into one [rtcmix~] and segregate by "setup" (script 0) vs. "run" (script 1) with this, see if you can tell! I'll discuss it in the next klaus

script 1 (setup):
// WAVETABLE(outsk, dur, AMP, PITCH[, PAN, WAVETABLE])

ffmult = $1

dur = 0.5
WAVETABLE(0, dur/2, 10000, 8.00, 0, wave)
WAVETABLE(0, dur/2, 10000, 8.001, 0, wave)

//MOOGVCF(outsk, insk, dur, AMP, inputchan, PAN, BYPASS, FILTFREQTABLE, FILTRESONTABLE)
MOOGVCF(0, 0, dur/2, 1, 0, 0.5, 0, ffreq*ffmult, 0.9)


WAVETABLE(dur/2, dur/2, 10000, 8.00, 0, wave)
WAVETABLE(dur/2, dur/2, 10000, 8.001, 0, wave)

//MOOGVCF(outsk, insk, dur, AMP, inputchan, PAN, BYPASS, FILTFREQTABLE, FILTRESONTABLE)
MOOGVCF(dur/2, 0, dur/2, 1, 0, 0.5, 0, ffreq/2*ffmult, 0.9)

MAXBANG(dur)


script 0 (run):
// WAVETABLE(outsk, dur, AMP, PITCH[, PAN, WAVETABLE])

ffmult = $1

dur = 0.5
WAVETABLE(0, dur/2, 10000, 8.00, 0, wave)
WAVETABLE(0, dur/2, 10000, 8.001, 0, wave)

MOOGVCF(0, 0, dur/2, 1, 0, 0.5, 0, ffreq*ffmult, 0.9)


WAVETABLE(dur/2, dur/2, 10000, 8.00, 0, wave)
WAVETABLE(dur/2, dur/2, 10000, 8.001, 0, wave)

MOOGVCF(dur/2, 0, dur/2, 1, 0, 0.5, 0, ffreq/2*ffmult, 0.9)

klaus8.maxpatch: add overall amp control with the MIX instrument

setup script (script 1) only:
wave = maketable("wave", 1000, "saw")
bus_config("WAVETABLE", "aux 0 out")
bus_config("MOOGVCF", "aux 0 in", "aux 1-2 out")
bus_config("PANECHO", "aux 1-2 in", "aux 3-4 out")
bus_config("MIX", "aux 3-4 in", "out 0-1")

ffreq = maketable("line", "nonorm", 1000, 0, 7000, 0.5, 100)

globalamp = makeconnection("inlet", 1, 0)

// PANECHO(outsk, insk, dur, AMP, CHAN_0_DELAY, CHAN_1_DELAY, FEEDBACK, ringdowndur[, inputchan])
PANECHO(0, 0, 999, 1, 0.125, 0.5, 0.05, 1, 0)

// MIX(outsk, insk, dur, AMP, p4-n: output channel assigns)
MIX(0, 0, 999, globalamp, 0, 1)



A few more notes:


• We looked at the Xcode project, saw where to set the target iOS version-level, noted the "ofApp.m" and "ofApp.h" files where we will be doing some coding.
• Talked about the RTcmix 'external' functions that we will use.
• Showed the use of ofLog(OF_LOG_NOTICE, "hey this is a printing statement") and where the output can be seen.
• Talked about the 64-bit problem with OpenFrameworks, hopefully fixed soon.

We'll be going over these things again and again in class.
