Hey, I'm doing a zoom talk for a Rotary Club on Pd/Open Source and want to do a small demo with a dinky AKM320 midi keyboard hooked up to Pd.

demos.pd

Open up [pd someone_else's_demo] and put another demo synth in there. The interface for input/output is super simple and documented in that subpatch. Alternatively, if you post an abstraction that fits that interface I'll throw it into the synth demos.

It can be a remix of the simple one I made in [pd sad_lonely_demo], or something completely different.

I'd like to collect at least five or six so people understand what open source is.

Went ahead and added some Karplus-Strong synthesis for a quick mandolin (plucked on note and note-off, which is handy for playing the theme to the Godfather) as well as a makeshift guitar.

demos-rev1.pd

It's neat how those low notes of the guitar sound similar to... a real guitar. KS has got to be one of the simplest synths that can get so close to a real instrument.

Added fm_lead, if that is the sort of thing you are after
demos-rev2.pd

@Balwyn Very nice! I might be able to play an excerpt from Eruption with that-- kind of Van Halen vis a vis Tony Kaye.

I also got a nice polyphonic glockenspiel from Matt Barber. Here's the current state, including your FM lead:

demos-rev3.pd

Oops, forgot Matt's abstraction:

glock~.pd

@jancsika Just at the wrong time........ too busy.
I would have liked to contribute with a polyphonic patch built on 51_string~.pd from the PMPD library.
It is another wildly different approach to string synthesis...
But I have no time for it.
Another day..
David.

@whale-av What is 51_string~.pd? I don't see that in the PMPD docs.

@jancsika In the examples...... but maybe [pmpd~] didn't make the latest versions?
51_string~and_others.zip
David.

Ok, I see it. Purr Data's search function didn't find it, which is unfortunate.

Report: Demo goblins ate my demo!

Luckily, I always plan for demo goblins so the talk went on alright.
