missing/useful [snake~] methods

[porres]

an issue to discuss and propose more [snake~] methods

• [snake~ nchs], get number of channels in a multichannel connection, useful to route signals according to number of channels and also to resize [clone], see https://github.com/pure-data/pure-data/issues/1989
• [snake~ mix], this method could have a 2nd inlet with a toggle and one could use it to mix all channels into one when on, or pass it unchanged otherwise. This would be an alternative to https://github.com/pure-data/pure-data/issues/1994
• [snake~ ltos] "list to sig" or something. Create a multichannel according to a list input. A bit like [sig~] but for lists and multichannels, it would also allow us to create a variable number of channels length.

what's the advantage of [snake~ ltos] over the enhanced version of [sig~] as suggested by @Spacechild1 ?

being able to create multichannel signals with a different number of channels according to the list input length

[Spacechild1]

I think these are all useful, but I would prefer different names:

[snake~ nchs] -> [snake~ count] or [snake channels]

[snake~ mix] -> [snake~ sum]

[snake~ ltos] -> [snake~ fromlist]

Two more methods:

• [snake~ split]: split multichannel signal into two (the split index can be set dynamically)

• [snake~ merge] or [snake~ join]: merge/join two multi-channel signals together

[abreubacelar]

since split feels like the verb from list split, merge could be [snake~ append] and [snake~ prepend] ?

[Spacechild1]

merge could be [snake~ append] and [snake~ prepend] ?

Prepend/append only makes sense for control objects where you have hot and cold inlets. For signal objects you only need a single method.

[abreubacelar]

oh, understand, i thought about avoiding crossed connections, but it is silly xD

and what about an object to take specific channels from a signal?

not sure about the verb... get/take/reorder... ?

[snake~ get 1 3 2 4] could take an arbitrary signal with n channels and swap 3 and 2 channels and return just a 4 channel signal from the n channel input, would this be possible with the current objects?

maybe this could even be used for a specific duplication of signals

[snake~ get 1 2 1 3] could take a 3 channel, and output a 4 channel with the third signal being a copy from the first signal from the input

if the number of channels is lesser than the number expected, so just insert an empty signal there

and we could also drop some channels

like [snake~ get 4 2 6 3] ignoring 1 and 5 and reordering everything

what do you think?

+1

like [snake~ get 4 2 6 3] ignoring 1 and 5 and reordering everything

I really like the get method because it is very flexible.

I miss "Magic Glass" more than anything else from Pd Extended. An enhanced version capable of showing multichannel values (and control values) would be useful. If that is not possible, then maybe an enhanced [print~]...? Also (sorry) in the Pd Help List of Objects.... patch, separating the audio objects that are multichannel capable from those that are not would be helpful. David.

@whale-av while all of your suggestions are related to multichannel, none of them is related to [snake~] itself...so they seem to be a bit ot for this issue. you probably want to create a separate ticket.
