Pure Data Guitar Synth/Sampler 

Its a bass

@@carloseduardogonzalezsalga7947 it’s a bass… *guitar*

we're learning how to use pure data and I'm finding it hella confusing. and I did python coding XD

@@MrChalmers99 it definitely can be but stick with it! It’s a totally different style of programming

@@MrChalmers99 i found it to teach me a lot about synthesis just by trying stuff out

:D

Hey! There's an object called sigmund~ that analyzes audio data and can output different values based on arguments you give it, this uses two separate instances of it. The first instance (sigmund~) just outputting the pitch of the signal in Hz, the second instance just outputting the amplitude (on a scale of 1-100). I'd had this integrating straight into a simple PD synth I built, so it didn't get condensed down into one MIDI stream, the amplitude value just went through a simple > operation that controlled the gate of the synth and the frequency data went straight in. That being said it shouldn't be hard to condense these into a MIDI stream, the frequency data going through an mtof object and the value of the gate that the amplitude triggers would just be converted to velocity data (though this would need to be scaled with a threshold to avoid string noise and other things spewing out MIDI messages). All of that could get packed and be good to go. Though a few things about this method: it works best when integrated into a synth because the frequency data updates constantly, which, if you were trying to pack into midi notes would output a constant stream of note on's them rather than one continuous held note. That being said, there is an argument you can give sigmund~ so it will try to detect the individual notes and only send updates each time a new one is played (sigmund~ notes), which is superior for general purpose MIDI integration, BUT this method introduces a fairly large amount of latency (at least on my system) so it made it impossible to play through. If you were just looking to record MIDI and manipulate it after the fact, though (sigmund~ notes) is what you're looking for. Hope this helps!

@@jackrooney513 thank you for your quick reply! I'll just go for sigmund~ and mess around with it. I've just built up a pedalboard running MODEP on Raspberry PI (see my last video if you feel) and I thought it would be great to use its wonderful generators, not only the FXs. Thanks again for your help! :)

aFunkyBass hey how did your project go? I’m interested in doing something similar but with a guitar.

Read Jack’s reply to aFunkyBass. He didn’t use MIDI, only pitch/amplitude detection.

it’s a bass guitar
