Hi guys, 247 reporting in. I made a simple, single oscillator ADSR patch using C&G’s and this [site](http://libremusicproduction.com/tutorials/creating-simple-synthesizer-pure-data-%E2%80%93-part-i) as a template. It’s pretty basic, just maps the ADSR envelop to the knobs. I literally had never looked at pd before today so I think this is a testament to how easy it is to get rolling and understand the concepts. There are still a few TO DOs like making the display output ON/OFF for sustain and having the aux button hop through octaves but I was too excited to share to finish those up tonight 🙂 Feel free to critique or add on! Thanks! [http://patchstorage.com/simple-adsr/](http://patchstorage.com/simple-adsr/) ---

Added the patch link since I was finally able to upload it, have fun! ---

Hi, Good on you for diving into Pd! Isn’t great? You should consider using the vline~ object instead of line~ since the former is optimized for high precision audio ramps. (Ramps may start and stop between samples, with interpolation as required.) You might want to have a look at the c\_adsr.pd patch in rjlib for a different implementation: [https://github.com/rjdj/rjlib/blob/master/rj/c\_adsr.pd](https://github.com/rjdj/rjlib/blob/master/rj/c_adsr.pd) Or the FLOSS manual: [http://en.flossmanuals.net/pure-data/ch028\_envelope-generator/](http://en.flossmanuals.net/pure-data/ch028_envelope-generator/) ---

Yeah, so far I’m digging it! Thanks for the links, I’ll be sure to check them out. When it comes to coding or anything like this I tend to jump in and hack/cobble my way through it til something works. Ha. ---

Nothing wrong with that; I also like to look at how others solve similar problems. ---

Do you think it would be possible to add this patch to basic sampler so the parameters on basic sampler are knobs 1-4 controlling ADSR?
