Hi,

Three questions

1. Does anyone know what command(s) I use to control a synth patch in Pure Data using the keyboard of my laptop?

2. Another thing I am wondering about is how I might control a synth with a piano. I have a midi to usb cable that I can connect from my laptop to the keyboard.

3. Are there any great synth patches available for download to experiment with?

thanks

I got it working using the spigot command along with a [metro 5000] attatched to a [delay 100] which checks the spigot on and off, so the data is only allowed to pass through the spigot during the time between the metro firging a bang every 10 seconds and the delay unchecks the spigot after just after every bang.

One of my last problems is how to define the length of the audio samples that I'm using. Right now, every sound I load up only plays in a one second loop regardless of how long the actual file is. I would like to be able to run the entire audio file on a loop. Most of them aren't too long..probably 7 seconds on average. I'm using the sampler.loop example to load my audio files, and I can't figure out what is telling it to only play one second of every file. In the easysample.pd file that you linked to earlier, I can load up an audio file, and it will loop the entire sound..

do you know what makes the easysampler dependent on the audio file for length as opposed to the sampler.loop which forces the audio file into an already determined length?

thanks

Could I use a -resize flag in combination with the readtab4~ command in order to automatically resize the array table that the sound file is read to?

I haven't really seen the actual examples you're talking about, but i've included an abstraction called simpleSampler. You could easily modify it so that it has another outlet that fires a bang once the sample has played totally (inside the sampler you'll find a number labeled "PLAY TIME", you can use this with a [del] object to trigger the bang). With a [spigot] you could then link the new outlet back to the play inlet.

Hope this helps,

Domien

I would love to take a look at your example, but I can't get it to open. when I unzip it and save to desktop, it appears to have no extension. I tried renaming it to a .pd file, but it wouldn't load in pd.

Mmm... posting something seems tricky... Maybe this works.

That's exactly right.

You haven't posted any code yet have you? You might need to do that if you you're still struggling to meet a Monday 11th deadline. I should be around this weekend mostly.

Possibly study the use of a message like

[1, 44100000 1000000]
|
[vline~]

(that's digit ONE, a comma, and 44100000 and 1000000, no commas)
don't worry that Pd immediately converts these to SI notation.

which is a catch all ramp generator. It says to vline~ start ramping up at a rate of
44100 every 1000 milliseconds.. for a long long time.

This solves most sample playback scenarios where you know only the sample rate but not the length of each file beforehand.

thanks for the help. would I place a command like the vline~ in the upper input of the [tabwrite] command?

I will attatch my file. It's very messy as I have been trying out a lot of things. I just need to figure out how to define the array in terms of the sound that is being looped.

Yes, [vline~] is used to index the sample table instead of the [phasor~].
I think the command you are searching for is the -resize argument for soundfiler, if you put that in your load messages things should get better. Stop sending things to the chunk size (scaling), unless you also want to modulate the playback rate. If you use the size of the file as the scale then a sweep from 0 tp 1 will play the entire file. Multiply that phasor by a fraction to get slower playback speeds. Look at the example Hardoff told you to, it's in there.

I'm sorry, i'm still not quite getting it...I think that patch i just posted is almost there, but i just really don't understand how to use that vlline~ command...

I was working on another patch since that i hoped my do what I wanted, and it's almost there, but it's still not quite right..

with this patch, i can define the array, and it will play the entire file in a loop, but now I can't figure out how to effectively change the frequency..any advice for the previous patch or this one?

thanks

ah, nevermind.

thanks for all of the help guys. I was able to look at an example of the sampler.transposition. Incorporating some of the things from that patched helped me work out the new patch and it works pretty well.

i was just reading this thread,trying to get a way to play a synth patch(i'm a newbie).
when i saw hardoffs suggestion,so i dl the casiosynth(nice synth btw) but only manage to copy/paste the complex data of 'pd pianokeys',but couldn't figure out how to just copy the object?(is that called an object?

oh,i've just realised you have to be in edit mode to copy the objects.
thanks.

hi spacedad (nice name

what you need to do is open the casio.pd patch, turn edit mode on (ctrl E), and then click once on an area just above the [pd pianokeys] subpatch*

then, with your mouse still clicked down, move over the subpatch, and it will turn blue. ..unclick

you have now selected the subpatch and can do a ctrl-x or control c to cut or copy it.

ctrl-p will paste it in another patch or anywhere you want.

* quick explaination of objects, externals, abstractions, subpatches:

1. object : anything included in the basic pd distribution (miller vanilla) - examples = [+ ] , [f ] , [tabread] ...etc

2. externals : basically the same as objects, but written by people other than miller... these live in your "extra" folder.. examples = [gemhead] , [makesymbol] , [freeverb~]

3. abstraction : a patch that is saved somewhere on your hard disk to be used inside other patches. you can tell that it is not an object because if you click on it , it will open to show the pd patch inside

4. subpatch : anything that looks like this -> [pd blah-blah-blah] - basically it is a patch within a patch, hence "subpatch"

thanks!
i've just tried joining it onto pd_doc_3's classicsynth eg.but not worky.
that had a kinda stepseq thingy which doesn't seem to be connected(but obviously invisibly is!)i've a lot of learning to do,but discovering the examples in the docs was good today.
i still can't get my midi keyboard to work either,once i get some kind of playabilty understood i should be able to experiment with some of the examples,it's just not obvious.

Maybe CTRL-D is what you want. That duplicates anything that is selected.

Be careful when you copy subpatches that you don't copy items that must be unique,
you will see a warning in the console about things being multiply defined if that happens.

thanks for the tips,
now i get,
'kee (x)...couldn't create.'
i thought i had it working but when i reloaded it,it didn't.hmm.

here's a better, newer version that doesn't need any abstractions:

http://www.pdpatchrepo.info/hurleur/pianokeys.pd

yay!thanks hardoff!

it's confused me,it now has 2 parts 'in' and 'out' how do i connect it to a synth?
cos the 's $0-transpose' and the 'outlets' don't have any connecting pins.

i was just googeling for pd help,when i came across obiwannabe's site.the six simple synths look like a good start to me.thanks for them.
i use synthedit (and i'm only new at that!)and pd is a bit different.
