Hello everyone here, Long time lurker first time poster. You've been a great source of info!

So I'm currently taking a class in sound design and I need to make something for the assignment he's set so I can get my degree, and I'm banging my head against a wall, As you can see in my patch, I have a way of loading in a loop, playing it and repeating, this is show on an array and I'm using a slider as a "Scanner head" behind the array.

But some major problems I'm having:

1. I have no real way of turning off the loop. If I bang the [t f f] then the loop stops, and if I toggle on the [sel 1] into the [pack] object then the loop starts, but from where I left it off not from the beginning of the loop.

2. I want to have some fx that will be able to be key triggable, nothing too complex, maybe have a [key] connected to a [sel key number] hooked up to a toggle for that sound. Currently I've got a [freeverb] on the [dac] and it works fine, but I've got no way of controlling how much reverb comes out, I've tried modulating the output of a slider to it but no luck.

3. And lastly do you know how to do a Ableton style beat repeat? As in go back in the audio buffer? I have been told to use a [phasor] with another one, and I tried but with no luck.

I'd really really appreciate any help anyone could offer.

Thanks in advance!

first of all: it would be nice if you'd clean up your patch a bit before you upload it, since it's hard to figure out what's going on, if the patch is full of unused objects and the objects are allocatedv messy on the screen.

if you want to use phasor~ for reading out the array you can set the starting point of the loop via it's phase (right inlet of the phasor~) --> see the attachment. you could also use e.g. tabplay~ (if you don't want to change the playback direction or speed of playback) or vline~ or line~.
for freeverb you can set several parameters via messages, like roomsize, damping, wet and dry sound..... to get a full overview, right click on freeverb and choose "help".
i attached a small example based on your patch.

what kind of fx do you want to add? what is an ableton like beat repeat? do you mean a stutter effect? use the forum search and type in stutter, i guess you will find a lot of threads.

Thank you very much for your help! I'll try and keep anything I put up here as neat as I can from now on

I have one more question, how would I tidy up the patch using sub-patches or abstractions, I'd like to have all the objects within a abstraction (or sub-patch) just leaving the bangs, toggles and sliders outside the patch with the array. I've tried putting them in a sub-patch and an abstraction but with no results. The file will load, and the waveform will display on the array but no sound will come out.

I've uploaded the patch with the abstraction so you can see.

Thank you again!

jesus... this patch is even as messed up as the one before..... :D
okay, please check the patch again, you have at least 5 or 6 completely useless objects in there. for example the [pd loader] subpatch (what is it for?), the nameless array inside the player abstraction, 2 sliders for the start position... why? and the slider for modulating the speed obviously can't work. the [*~] before the [tabread~ $0-sound] is not connected on it's right inlet, so it will multiply it's left inlet by zero (what's the result of a multiplication by zero?). the inlet of your player abstraction is an audio inlet, but you feed 2(!!!) control signals to it.
please - i want to help you, but i don't know where to start!
to work with subpatches: you can work with the "graph on parent" feature to make nice guis. i will upload an example later.

Sorry for the confusion, Id been trying to make this work all day and left it late ast night thinking it was tidy. The reason I have multiple start points is to have the abiliy to quickly jump into points within a loop, for example I'm using this with a drum break, so if I have multiple start points I can jump back and repeat say a snare hit. The speed slider was working, at least before I put it in the abstraction. Everything was working as I wanted it, but I know there must be a much more efficient. I tried to replicate the patch within the abstraction, as in connect all the objects to the inlet in the same way as I did when the objects were out of the abstraction. I also tried putting a graph in the abstraction, over sliders I wanted to have in the parent patch and ticked the "graph on parent" box, but again it didn't work properly. I'm pretty new to this, so sorry if I confused you

okay, at the moment i have not enough time, i will have a look at it again later. but as far as "graph on parent" is concerned, you must have got something wrong: you don't need to add a "graph" object into the subpatch, but do it like this:

• in the main patch create a subpatch e.g. [pd subptach].
• right click on it and choose "properties".
• activate the radio-box "graph on parent"
• you can choose several options in the "properties" window, but we leave the rest as it is for the beginning.
• hit "ok"
• you will see, that [pd subpatch]'s frame now is 85 px * 60 px (you can change these settings in the properties if you want to).
• now open the [pd subpatch] and create e.g. a toggle (ctrl+shift+t) inside of it.
• you will now see a red frame with 85px*60px inside the subpatch. move the toggle into this frame. every gui element (graphical bangs, toggles, radio buttons, arrays, sliders,.......) within this frame will be displayed later in the parent patch (here in the main patch).
• close the subpatch, and prove if i am right. the toogle should now be visible in the main patch.

....connect all the objects to the inlet in the same way as I did when the objects were out of the abstraction

believe me, you didn't! there were at least 2 wires to differen targets that you had to handle before you created the abstraction, but your abstraction had only 1 audio inlet.... 2 targets - 2 wires - 1 (!!!) inlet? this can't work. how should pd know, which signal is for which target? did you want to make something like a multicore-bus?

okay, i have had a look at your patch, i didn' t care about if things make sense to me but i cleaned it up and built a pretty simple gui with a "graph on parent" subpatch. please, take your time and figure out all things that i changed in relation to your previous patch. if you than have explicit questions, just ask again here... hope i could help you.
