i was thinking about "recursive patching" lately, meaning to call an abstraction inside of an abstraction inside of an abstraction inside of an abstraction inside of an abstraction inside of an abstraction and so on.
It is clear to me, that this has to be done with dynamic patching in order to stop the process at some point. So the question is not how to implement this, but in what case something like this could be useful? Do you know of any "recursive" patches? The only thing i can think about are reverberators and i actually tried this using a feedback-delay line inside of a feedback-delay line inside of a feedback-delay line inside of a feedback-delay line inside of a feedback-delay line inside of a feedback-delay line feedback-delay line inside of a feedback-delay line inside of a feedback-delay line.. with rather unimpressive results.
Any ideas?

Similar to [pack ] and [unpack ] but instead of the default atom type being a float, the default type is anything.

Also comes with a new creation arg 'a' for anything. Numbers and unrecognized types will also default to anything.

For strict type checking, use f(loat), s(ymbol), and p(ointer).
The pak object will also store unrecognized types as symbols and interpret 'b' as a 'bang' symbol.

You can send lists to any of the additional pak inlets and it will store the list values with the inlet as the starting point. For example, sending the message [foo bar 3 baz( to the 2nd inlet of [pak 1 2 3 4] would result in the list: 1 foo bar 3

The example includes another object called [x ], which is a kind of trigger object that dehusks lists that consist of only 1 element when you use 'a' or nothing for creation args. For pd-vanilla users, the example also requires zexy's [demux].

You can also use "." to skip inlets and assign only specific ones.
For example, sending the message [. . 123( would assign 123 to the 3rd inlet and leave the first two values the same as they were. You can send these messages to any inlet.
The skip arg feature only applies to list and anything type messages, so if you really want to, you can still assign a single period to an inlet by sending it as a symbol.

There are two more objects [@pak] / [@unpak] - reverse pak/unpak, which output the lists in reverse order.

Strict-type error messages are muted by default and to unmute them, you need to send [mute 0( to the 1st inlet. The number sent to mute acts as a bit mask for the inlets, so when a bit is turned on, the associated inlet will output error messages.

pak-unpak.zip

Returns a boolean 1 or 0 if the value sent to the 1st inlet matches the type specified in the creation arg or 2nd inlet.

You can set the type to be matched against either as a creation argument or with the message [type $1(, or by sending to the 2nd inlet either the type name or an example of the atom whose type you want matched against.

EDIT: the "type" method needed a bug fix. The help file has also been slightly altered:

EDIT2: Now the type can be virtually anything, rather than one of 5 possible types. This allows us to check for specific messages. For example, sending the message [foo 1 2 3( to the object [is foo] will return true.

EDIT3: Defaults to float if no creation argument given. Also added a pointer example to the help file.

EDIT4: A memory-freeing method was necessary to clear the proxy inlet.

is.zip

@s.elliot.perez "comb filter" refers to 2 simple delays: 1 where you delay the incoming signal, multiply it, and add it to itself (no feedback) and 1 where you take the output, delay it, multiply it and then add it to the input to create the new output (this is the classic "echo" effect and what we generally think of when we think of the "delay" effect with feedback)

the fundamental frequency is equal to the inverse of the delay length (e.g. if your delay length is 1 ms your frequency will be 1000 hz). I don't think the bandpass filters should affect it too much.

in this situation, the delays are feeding back into each other so it's more complex than a simple comb filter. However, the frequencies should still depend on the delay times like that.

Interesting side note: all digital filters can be deconstructed into these 2 simple building blocks, except that they use 1 sample instead of milliseconds or seconds. The feed forward one is called a "zero" and the feedback one is a "pole". This is because the space between the peaks of the comb filter is the inverse of the delay time. So, if you set the delay time to 1 sample you get a "peak" width of the entire spectrum up to the sample rate.

I think you did it right, but you might need to lower your block size within a subpatch to get lower delay times than 64 samples (~1.45 ms @44.1k) also.. and/or do the stuff in the helpfiles G04.control.blocksize.pd and G05.execution.order.pd where you can

"The PD trees sometimes bear unexpected fruit."

The zip below includes 29+1(raw) standardized effects (esp.) for use with MobMuPlat.

mmp_effs_collection.zip

They all work and have been standardized in the following manner:

1. all are MMP-compliant (so include only objects which MMP supports)
2. have 3 inlets and 1 outlet~
3. the inlets are (from left to right): the incoming signal (i.e. inlet~), the parameters(3), and a switch~
4. the effects have all been finessed to only include <= 3 parameters
5. the parameters are sent to the second inlet via [0 $1(, [1 $1(, and [2 $1(
6. the switch is a toggle so 0|1
   and
7. each window is 186x116 pixels.

I have included an .mmp file to listen to and test them with either adc~ | randomnotes. It also includes a bypass toggle , three parameter knobs (which load the parameter name to each label once an effect is chosen), and a gain. Only the selected effect's switch is turned "on" so it is very low on the cpu.

The MMP file, in and of, itself may prove useful to someone as it packages in a single place a 30-effect "pedal-box".

That however is not why I am sharing it.

Since the effects are standardized and mmp-compliant, my hope/thinking is others may include them in their work no matter what it may be and thus build their patches, apps, etc., using the effects as building-blocks.

I have accredit the original effects designers by adding a suffix (in parenthesis) to each effect as follows (in alpha-order):

d=DIY2 Collection
g=Guitar Extended
s=Stamp Album Collection
v=scott vanya (me)

The included effects (basically the best I could find that lent themselves to 3 parameters) are as follows:

audioflow(v).pd
beatlooper(v).pd
bodyresonance(d).pd
chorus(s).pd
delay(3tap)(d).pd
delay(fb)(d).pd
delay(pitch)(v).pd
delay(push)(v).pd
delay(revtap)(g).pd
delay(spect)(d).pd
delay(stag)(v).pd
delay(tbr)(v).pd
delay(wavey)(v).pd
detuning(g).pd
distortion(d).pd
filter(s).pd
flanger(s).pd
hexxciter(g).pd
looper(fw-bw)(v).pd
octaver-harmonizer(p).pd
phaser(s).pd
pitchshifter(d).pd
reverb(pure)(d).pd
ringmod(g).pd
shaper(d).pd
stepvibrato(g).pd
streamStretch(v)-help.pd
streamStretch(v).pd
tremolo(d).pd
vcf(d).pd
vibrato(d).pd
vibrato(step)(g).pd
wah-auto(v).pd
wavedistort(d).pd

Note: there are too many effects to go into detail about what each parameter does. So I leave that for you to either figure out/discover on your own or post here your question and I will answer it as time/energy/etc allow.

Peace and Loving Music Through us all.

Sincerely,
Scott

Here is an updated version
arguscore-update.zip
and a few Purr Data compatibility replacement objects: purr-data-compatible-replacements.zip

A creation argument only object driven system for instant music making;
Objects so far;
Required;
globaltimer  - outputs a 10ms bang to drive all objects;
globalsync   - resets all objects to zero or start;
audio~  - dac~ catcher~ for all throws~, output level, mute;

Sound Objects

By default sound objects start playing at the bpm of the first argument

basspump - args - bpm note distortion duration
wood - args - bpm note duration
tremsaw  - args - bpm note vibrato distortion duration
tremsine - args - bpm note vibrato noise duration
noisy - args - bpm note vcfq duration
kauplus  - args - bpm note string-resonation duration

Effect Objects

sqr - args - 16 required(0 or 1) bpm (starts playing by default)
                          overides sound objects autoplay
                          2 optional args for cursor offset and pitch if font different
                          has 16 outlets to send 0 or 1

isolator - sits between two sqr's and sends a signal to start/stop the receiving sqr
seqnotes - four pairs of note & velocity that receive sqr ones to fire a connected sound object

Notes
Can crash Pd when making lots of edits to arguments, particularly while playing, so save often
There is a [declare -path objects] hiding behind the audio~ object
Fixed missing note and velo message for tremsaw
Two more arguscore patches can be open at the same time providing only one patch contains the globaltimer and audio~ objects (see arguscore-2.pd and arguscore-2-b.pd)
new objects
kauplus, autopan, fade, filter, stop-delay-secs, stop-delay-bpm;

Audio Ideas (AI) Collection (placeholder) currently only links

per @LiamG 's kind suggestion I have begun the process of consolidating my abs and patches, etc. into a single location/zip file or for possible upload to github.

Just to get the ball/me rolling and scope the work I got the links for my shares into a single location to later be consolidated into the single AI Collection.

For now at least, please, bare with me (and the links below) as ideas I am more passionate about currently are demanding my attention. (Which funnily enough will probably also be included in the set, where ever they are shared.)

Thanks, for your patience and all you do for the Pure Data Family.

Sincerely,
Scott

As I mentioned in a previous post: "idea: "riding the wave"delay length triggered by env~ size (link http://forum.pdpatchrepo.info/topic/10557/idea-riding-the-wave-delay-length-triggered-by-env-size)", I had been wondering about controlling a delay line via the env~.

pushdelay~_sv-help.pd
pushdelay~_sv.pd

My idea had been to mimic the "power" of a wave (akin to what I have been suspecting we will do once we figure out how to harness the power of gravity waves): the larger the amplitude > the further the auditory "ripple" and the longer it lasts.

The abstraction below, pushdelay~, is my incarnation of that idea.

Ciao!

Much merriment thru you and yours.
Scott

-help (from the -help comments):

In this pushdelay~ abstraction the length of time on the delay line, as well as feedback, are driven by the amount of the env~, the larger the env~ the longer the delay time and more feedback there is.;
In "inter" (interval) mode, the abstraction takes the current delay time and sets a metro to that time;
opens a spigot and captures the maximum value for the env~ during that period then sets the next delay and metro times to that value.;
In "cont" mode, it sets the delay and feedback times continuously based on the envelope value.;
The relationship between the delay(x) and feedback(y) values can be set using the curve ctrl, either linear, convex (sinusoidal) or concave (also sinusoidal but inverted).;
Turning the abs either off|on starts the inital metro.;
If in "off" mode, the delay ctrl may be moved independently. However the feedback will still change the same way, mentioned above.

-enjoy;
svanya

p.s. the original delay~ abs is from the DIY2 collection.
