Play pitch loop object question

#10

Tried it both in Windows and Mac, no loop...what am I doing worng?

#11

Sorry, never really understood it. Maybe it is time to take a look at it again :smile: WiIl look into it.

#12

Thanks.
For its weird too. It should loop. With a 512 size table, loop end set to 512 should loop. But doesn't :smiley:

#13

Yes, I think that is what I concluded last time I was messing with it and gave up. I don't think I was doing it right, even with the above description. Anyway, I am just connecting Axoloti now to give it another go.

#14

Yep still no effect here, following above description.

Hi, it doesn't work to me neither...
Could somebody post a basic working patch of adjustable loop lenght ?
Thanks

#16

Hm...
I was trying to create some kind of granular synth, with random play position, but its useless without the loop function.
Maybe Johannes could explain what is wrong...

#17

Bump for solution :smiley:

#18

I suspect @johannes may have had an issue when he checked it in, since I see no reference to loopstart/end in the code i.e. the params are declared but not used.

@johannes perhaps check your hard drive.. otherwise I suspect you may have lost an edit somewhere :frowning:

#19

Thanks for looking into it @thetechnobear

Many have tried with same result, so there is definatly something (not) going on in that object.

#20

has anybody had any success with this ?

#21

bump, because i would like to use this too.

#22

Doesn't seem to be working here either

#23

as i said previously, loopstart/end have not been implemented.

I think the problem is to implement this 'as is' would be inefficient...
the table lengths are powers of 2, so that we can determine positions by bit shifting, setting arbitrary end points breaks this.
(working on the assumption (for being useful) is that pos = 0 , loop start and pos = 64 (100%) = loop end)

what we could do is:
- allow arbitrary start points. (this is just used as a simple offset)
- change loop end, to loop length, where powers of 2 are offered.

this would not allow for arbitrary sample lengths (just 2^x) , but would allow for handling processing many samples from the same wave file.

I will also add loop start/end are currently parameters, it would be more efficient to have these as attributes (compile time change) , it would be nice to have a variant with inlets, but the issue then is how to 'insist' the length is 2^x.
(I think its these oddities, that mean table parameters are usually expressed in % (0-64) rather than int indexes)

#24

would there be a way to have it just loop over the whole buffer? this would help me already.

cheers,
c

#25

Use a sawup lfo to play through the table.

#26

thanks. how do i set the saw up's frequency correctly? as in that it has the correct frequency so that it matches the length of the buffer?

thanks for your help
bests,
c

#27

This calculations to get the hz for the lfo:
Sample rate/sample length

Example:
So Axoloti has got 48kz sample rate, that is fixed and for the example we use 262144 sample length.

48000/262144 = 0,18310546875 hz

Set the lfo to approximatly 0.18hz

#28

thanks for the help. i've tried this. but it seems that it actually is retriggering the table beginning rather than actually going through the table. here the patch.play pitch looped.axp (4.9 KB)

#29

just did this:

it's in the community library (1.0.11 required)
