@simmit123456789 You could try editing the /boot/config.txt file and enable the hdmi_force_hotplug=1 option. It should then load the hdmi driver even though the screen is not present....... which might allow it to continue normally and load the usb drivers.

@Krischomat It depends what you want....
I wasn't shure what you meant by length but having assumed that it was the playback length I had prepared this........ sliders.pd
As I was unsure and others had posted solutions I kept it back but maybe it is useful.
It seemed to me that the options are fixed length or fixed end position.

The range message can be applied to the sliders according to the actual (total number of samples) length..... or a better solution is to add some calculation, keeping all the sliders in the range zero to one which makes for easier use of [phasor~]

@FFW You can hold it in [f] on its right inlet if it's a float.
Or [symbol] or [list].
And then bang it through from a trigger at the output of the abstraction....
[t b a]...... left to float..... right to [print b].
David.

@jenkutler The cyclone library has a few signal rate objects that find crossings.
[edge~] is probably closest to [togedge].
To synchronise a zero crossing to a control event [zerox~] can be fed into [edge~].
For more accuracy [zeropos~] will give the number of the sample within a block when the event occurred.... and the direction of travel........ but of course you still only receive the message once the block has processed.
Their help files will give some more information.

@raynovich Yes. Put everything in a zipped folder (a .zip file) for the upload. No need for embarrassment.
David.

@raynovich I can try it if you upload the abstraction la_loop_v02.pd.
It is a strange problem as all that your message does is place the abstraction in the sub-patch...... it should be the same as your doing so manually.
David.

@raynovich I think it must be a problem with the contents of [la_loop_v02]
Are there any error messages in the Pd console when you create a second instance manually?
Have you used $0 in any array name and send/receive/throw~/catch~ names so as to differentiate the instances?
David.

@seb-harmonik.ar Yes...... it contains your Purr Data code for splines, but does not produce curves...... I think because of missing variables from your mod.... maybe/especially ${wind}.c
So the result is "segmented"? cords as in the screenshot in my first post above.
But maybe only in Windows OS.
David.

@60hz Yes...... a tcl plugin.
Derived from the hard work put in by @seb-harmonik.ar............ https://forum.pdpatchrepo.info/topic/10943/a-little-pd-mod
Curves have eluded me so far although maybe doing his whole vanilla Pd modification would work (not sure using windows7).

It requires sys_gui from the hcs library to send messages to tcl if you want to turn it on/off.

@jameslo Yes, the removal of the symbol tag is a bind. A list can contain one symbol, but as the list tag is removed the symbol tag is not added back (flawed analysis... see below).
Passing [symbol woof( through [$1( also removes the tag.
It is a mess.......
I remembered all that after I had gone to bed.

"text" really needs to disappear as a type........ as we discussed before.... a single atom symbol needs to be always tagged as a symbol to simplify message handling.

There is a solution however......... unintuitive and without logic........ passing single atom "text" through [list] does not add the list tag....... probably because it is not true to type.....
It adds the symbol tag.......... this..pd
