I'd like to use a Raspberry Pi (Zero) as a snare drum for my drum computer. That drum computer sends midi note 40 (= E2 on a Midi keyboard) if the snare drum needs to sound.

Is it possible to let Pd Vanilla react to ONLY Midi note 40? And only to the 'note on' message, not the 'note off' message? I've tried it in Ingen and there it (almost) works, but there is no Ingen package for Raspbian (= the OS of a Raspberry Pi).

@MeneerJansen This should do it:

@MeneerJansen Midi is not my thing, so someone might well post the established solution...... but this will do it...... this.pd

Thank you for your fast replies. Works like a charm! Now for a patch that emulated that super snappy Roland TR-808 snare drum.

In the video below somebody managed pretty well to emulate the 808 snare, however the resolution of the video is too low to read text. Therefore I cannot replicate it...

@MeneerJansen here is another very nice (not only) snare emulation patch from @mianmogra that you can download: https://forum.pdpatchrepo.info/topic/12015/mymembrane-acoustic-drum-synthesizer

@MeneerJansen Looks like in the video there is just a sample being played...

Hello everyone, thanks for the mention @Jona!
@MeneerJansen That TR-808 snare is for a client, so I'm unable to share it.
On the other hand, here's a more basic TR-808 kick and snare, it has the basic blocks for it: kick-and-snare.pd

• One oscillator with two harmonics, each harmonic has its own envelope curve and one is more snappier than the other.
• A filtrated noise source with more decay time than the drum layer

You can make it snappier by distorting the first milliseconds.
If you know synthesizer terms you can try and emulate it better using to Adam Schenider's tutorial to make an 808 style snare.

@ingox There is a sample being played for comparison with my synthesized version.

@mianmogra Ah sorry, i was at work and just took a brief look at the patch in the video, even without listening to the audio, my apologies!

@mianmogra Thanks for the explanation, the .pd file and the hints. I'll go and work on it.
