Good Morning PureDaters!!!

I'm here other time asking about some pure data objects which i don't control at all.

As I told in another post, i'm currently doing my final project for my degree. It`s about sound effects developed at Pure Data. At the moment i have done a compressor which sound really better than the other ones which are a reverb implemented as moorer way, and a parametric eq.

I have having problems with some objects which i think doesn't run as they should.

They are send~ and receive~ and in the other hand throw~ and catch~. The problem is that i need to send the signal sample by sample because i need to delay the feedback signal just for one sample. The matter is that when i try to send it blocking the patch for one sample pack with block~. The problem is that when i use those objects appears a problem which say:

sigcatch 1243-signal1: unexpected vector size
throw~ 1243-signal1: vector size mismatch

or

sigsend signal1: unexpected vector size
receive~ signal1: vector size mismatch

Then i would like to know if exist another object or way to make it runs.Or if is it a bug in Pure Data. In case it would be a bug i must write it in the memories of the project. Then, i would like to be sure about what i will write.

Add to it i have another issue which is about the play objects. I'm working at the moment in a new patch to make a delay effect which runs which the tirhm of the song. I started to do it with something like a click which will let to configure the delay by each beat. Then, if i have a "¿PATH?"(i'm not sure it would be the word) which have any time or beat for instance 3/8 in 85 B.P.M. i would like to have 3 delays at the speed of the quaver note rithm.How ever i can't find an object which permits the sound flows when i play for instance the second of the three consecutive delays.However all the objects i have tried stop the sound when i try to play another delay above them, and if i try to do it whith consecutive delays i can't completly stop the 4th delay. Then i would like to know if anybody knows what i could do.

Then, those are my two issues i have today. I hope anybody was able to help me with them.

Thank you everyway. And excuse my english skills but i'm learning. If anybody want correct my enlish i'll be so glad.

from the send~ help patch:

[send~]/[receive~] only work for the default block size (64).

I assume it would be the same with throw~ and catch~, you need to use cables or maybe tabsend~/tabreceive~?
as a side note, zexy has the z~ object with delays one sample

User acreil explained how to solve your delay problem (without using the z~ object) in another thread:

You want to make subpatch with block size 1. In that patch, you create an array of length 1 and then write/read to that array. This has to be in a separate patch because dac~ and adc~ require block size 64.

Regarding your second question, I do not know what you are describing as the "play object". Maybe attach a patch.
