@deframmentazione-geometrica I must have made this for someone in the past..... so it is probably on the forum somewhere....... sweep-explained.zip
It uses [line~] ...... audio rate sweep..... instead of [line] which is control rate and which can be too granular for large rapid differences.
David.

@ultraman I have had the same problem in windows...... the Pd executable "orphaned" in the background.... when it has not successfully disconnected from the soundcard when closed.
As @seb-harmonik.ar says....... wish has closed, but not Pd.
Reopening Pd then fails as it cannot hook into the soundcard.
Particularly when starting Pd with command line switches that determine the audio settings for an ASIO device.
Had to kill the process in task manager..... which is presumably "force quit" on a Mac.
As @ddw_music I suspect a hook...... and 100% an audio hook to another program or driver.
David.

@ddw_music Glad you found it.
My mistake in the previous post not noticing that you had accessed the help browser..... but the help-browser is set to look only in the "extra" folder unless paths are added in the preferences pane.
But the point still stands if you have more than one version of Pd on your computer..... it is best to name them as the shared registry paths could be looking at a different flavour of Pd.
See x4.htm in the Pd/doc/manual for all information about Pd objects, externals, user directories, library types (single and binary) and search paths.
The magic location is the "extra" folder.... as it always has been.
David.

@ddw_music Are you looking at the same directory?
If you have multiple copies of Pd a newer download can still be pointing at the directory of a previous one in the path preferences...... as the registry entry is shared.
Maybe a stupid question as I am win7 only and maybe the "This Pc" is a system shortcut to "/Users/gary8" in later versions.
But I cannot imagine that some folders would not be listed in a directory listing.
David.

@ddw_music I am not a musician so...... but this might be a starting point...... rtc library and uses other "extended" libraries. [list-len] you can change to [list length] for vanilla....... and [bassemu~] is just part of the final midi "player" and so should be replaceable scale.zip
I know [list-idx] can be replaced.
If you check it out in extended and it looks like it is useful then I can work to make it vanilla compatible today.... there are quite a few other objects to replace.
David.

@cfry @katjav made a vanilla abstraction to replace [freeverb~] that might help........ https://github.com/derekxkwan/pd-vfreeverb
I use [reverb282~] which registers no load in my task manager, but it is not vanilla....... R282.zip
But [freeverb~] doesn't cause any cpu issues for me either.
Reverb is a load of recycled delays and some filters so reducing any complexity is going to reduce quality...... there will be a trade-off.
David.

@Alexwfm If you have lots of ram, and you probably do, then preloading is a good solution.
If it will be just one set of samples then you could also save them with the patch (right click the array properties and set the save option).
You could also use [readsf~] if you have good disk access times or an ssd.
It loads a small part of the sample and starts playing instantly...... loading the next part as necessary..... but as with the array you will need 36 [readsf~] objects if you want polyphony.
Have a look here..........https://forum.pdpatchrepo.info/topic/13057/read-multiple-wav-using-readsf
David.

@ddw_music It is often forgotten that [metro] is the Pd metronome and it will take beat length messages though not quite as "musically" as quant for TempoClock.
So bars and beats can be sent separately with two tied [metro] clocks or one and a counter.
Could you run a global [metro] clock that bangs tempo message changes through to [timer] [text] [delay] [qlist] only at bar lines?
It looks as though [delay] and [timer] will update any remaining delay if they receive the message at other times. [text] doesn't say, but might behave the same way? If it does then you could allow tempo changes at any time for more interesting rhythms.
Then you could have a bar "lock/unlock" switch.
The global [metro] could be tied to audio maybe, It looks as though it will take the samp argument just as [delay] does.
David.

@ddw_music Then I don't think so. It seems [makenote] has had no update since Pd 0.33 (extended was Pd 0.43.3 in 2011) and it still only has velocity and duration in msecs arguments.
David.

@tiemget You would need a trigger in there to control the order of operations.
Or this might work although as @old says...... hard to know for sure......
David.
