[mymembrane~]
A synthesizer focused on the creation of acoustic drum-like sounds.

Patch available here:
https://github.com/MikeMorenoAudio/pd-mkmr/tree/master/06-Instruments

Demo:

Thanks! I'll probably port it to Camomile and Heavy VST in the future.
I also need to document this for future reference,
Documentation and promotion is half the battle lol

Very nice work, it sounds great !

this is great! i downloaded your mkmr abstractions earlier, but i think you really are getting to very nice places with this - especially the snare drum sound is pretty convincing.

i would be really interested in getting your advice on some of your other instrument patches like [mct~] and the [piano~] patch. i would really like to know how to extend the basic karplus setup so that it could work for modelling a piano string, but i want to also be able to change the timbre in a variety of ways. your instrument patches really sound great, but i would love to know what to tweak in order to make them sound more unusual and experimental. can i message you here with some questions on this?

Sadly I don't understand how GitHub works. Could you post a link directly to your pd-file?

@Nobody it's actually pretty easy. if you go to his github link he posted you'll see a pd-mkmr link listed near the top. click on that link for the main repo page, and there's a green button on the far right corner that says 'Clone or Download'. click that to get a zip of the repo. unzip that file and inside are all the patches from the whole mkmr collection and it should be under the Instruments directory. hope this helps!

@mianmogra thanks very much! i was a bit confused with some of your other mkmr instruments but this object had just enough information for me to unpack one of the [mymembrane~] objects and see how you put it together. i started doing some modifications to the patch and i'm happy to say i'm making good progress! interesting that allpass filters are so useful.

i'm not great at DSP theory but i've been wanting to adapt a Karplus-based instrument to get something more interesting and expressive, and this finally cracked the door open a bit.

what i'm really interested in is creating a close approximation of a piano string that i can then mess around with to get more timbres similar to prepared piano. i was impressed with your [piano~] patch as a completely synthesized representation (even if it's a little cheezy sounding) but i couldn't figure out how it worked to modify it. i'd like to ask you more questions on this in the future if you're available. thanks!

Thanks! With your help I succeeded in downloading the files. Great program!

@mianmogra Great work!

@metaphysician Sure thing, ask away here or in a private chat. My discord username is Mike Moreno#1780
[mct~] is additive synthesis using different envelope curves for each harmonic.
[piano~] is pretty straight forward, just 3 karplus-strong operators a little bit detuned.
I still want to make a better, more realistic piano sound, but in order to do this I need to understand how to create inharmonicity using allpass filters.
Judging from an spectrograph of a piano sound, the upper harmonics seem to be gradually shifting from the fundamental frequency, there's even a little bit of pitch modulation. Here's a good reference using additive synthesis min 1:46
