Hi!

Is it possible to make a polyphonic synth that receive chords as an array/list of values? Something like this MIDI patch:

I've tried it using [clone] but could not manage to send the lists to the clone object. Here is the hard coded version that I am using:

Any externals for dealing with that?

And here the patch. polyphony-chords-as-arrays.pd

Thanks a lot!

i would say "no" - there is no known generator or filter which is polyphonic by nature.

even if you code your own external at one point you always have to iterate the list into single values.

for example you could use a vexpr object instead of 4 mtofs, but there is no method how to make a polyphonic phase accumulator.

if you would try to make one, you would soon find out that it does not make too much sense to process accumulators in vectors when you need to have single outlets anyway, since audio connections have a fixed rate and bitdepht and can not be used to carry more than one signal.

of course inside pd you can yourself freely *where *you do that, (as opposed to MIDI, where every communication is serial.)

Your [clone] idea would be the way to go!
@Obineg said in Chords (polyphony) as arrays/lists:

if you code your own external at one point you always have to iterate the list into single values.

And have a look into the help-file of [clone]: Adress clone instances with the first number of a list or with next in a serial manner.

Instead you could send the whole list to all and in each instance cut-out the snipped of interest by getting the instance-# with [f $1] and cut-out with two [list split]s.

Maybe upload your non-working clone-version and we can fix it.

In your hard-coded patch only [mtof] and [phasor~] or only [phasor~] are required to duplicate, - sum all the [phasors~] into one [lop~] ect.

Maybe use [poly], if you like it.

Also, there are many examples of polyphonic synths floating around, in the patch-subforum for example.

Thanks a lot!

This is what I managed to do with [clone], it seems to be a strange solution, a toggle feedback for doing vertical chords (all the notes at the same onset). Any other proper solution?

Here is patch.

synth.cl.pd chords-clone.pd

BTW any other solutions/ideas for doing arppegios are welcome...
