Hi everyone,
I simply want to trigger a polyphonic instrument with a fixed envelope.
I understand subpatches/abstractions and have used them successfully (for monophonic instruments), but I cannot wrap my brain around poly, pack, route, and unpack.
Furthermore, trying to access pack or unpack's help page is consistently crashing pd.

On top of that, all the examples I'm finding rely on a midi controller with pitch and velocity. I don't have one/want to use one.

Thanks.
Jesus, that's really the simplest way to do it?

I've no idea - honestly I just started playing around with using $0 and creation args ($1, $2, etc...) as names of sends and receives today and I'm pleased that it's increasing my efficiency.

See /pd/...../stuff/synth/1.polysynth.pd

Much more flexible, and not much more typing than mine, just a greater degree of fluency - the documentation (and extensive help files) are perfect.

Hi, mates!
I don't have a big experience on Pd but PonZo's keyoscy is a quite simple approach. One of the most difficult tasks in programming anything in any language is making things effective and simple at the same time.
Thank you for sharing!
Best regards,

Sumidero

Seriously, thank you.
I hope I didn't sound snarky above.

Where is this /pd/...stuff/synth/1.polysynth.pd?

Make sure you have the latest version of pd-extended:

http://sourceforge.net/projects/pure-data/files/pd-extended/

Or at least, pd extended

and if you're mac you have to "control-click view package contents" BS to navigate through all the folders of *.pd 's. But it's all in that folder.

The ccrma build apparently leaves these out. :-/
Thanks for your help and the link.
Did you used to hang out on irc for lgpt ?

This patch uses canvas objects to display which notes are being played on a qwerty keyboard as they would appear on a musical keyboard. Depressed keys in graphic musical keyboard change color with associated qwerty key keyup events.

yowsa, that's two great examples. thanks folks.

"I just want to make a single [osc~] synth in a subpatch, with an Attack/Release envelope, and control a couple instances of it."

You don't need pack and unpack to accomplish this

You can use mtof or google and find a chart of the frequency values you want to trigger and vline for your envelope.

[key]
|
[select (desired keyname)]
|
[1 15, 0 3 30[ <----see vline help
|
[vline] [osc~ (desired frequency)]
\ /
[*~]
|
[dac~]

using the same key for attack and release results in re-attacks which i dislike. see attached for a "more better" solution using 1 for on and 2 for off.

Just make a ton of those and send them to the same dac. You might want to multiply again to reduce volume or use a vslider to turn volume up and down.

Oh, if you're just starting out like me i highly suggest you checkout cheetomoskeeto (hdez on here)'s videos on you tube.

Here's what I'm using for this these days:

Uses spigot a lot.
