Pure data keyboard patch

Only users with topic management privileges can see it. Loading More Posts. Thank you both for your suggestions. I will try them this afternoon. Well, thanks again! Ah, please youaresound, testing your patch, I've solved everything but this: you Loading Categories Disabled Categories are greyed out This topic will be moved to the category.

What makes this example interesting is that the oscillator shapes can be altered by clicking and dragging over them with the mouse. The oscillator waveforms are stored in Arrays the three boxes along the top of the screen in my example , and samples in a variety of formats can be stored within Pure Data in this way. This wavetable synthesizer shows something of what Pure Data can do when it comes to audio processing, and it also includes a built-in step sequencer.

The sequence can be edited with a MIDI keyboard, while wavetables can be drawn on with a mouse. The sequencer section of my example is at the bottom right-hand side of the picture. A clock object called Metro short for metronome, though this software was originally written in Paris! The counter tells an object called Tabread which step of the sequence it should read.

The tabread object outputs a MIDI note number at each step, and this number determines the pitch of the wavetable oscillator. The sequence can be edited using a MIDI keyboard via the Notein and Tabwrite objects , or by drawing directly on the graph at the bottom right of the screen.

If you wanted to, you could adapt this patch so that the oscillator waveform could be drawn using a knob or slider, or by running your fingers up and down a MIDI keyboard or just up for more of a sawtooth wave. An input device like a Korg Kaoss Pad or joystick could also be used for this purpose. Pure Data is being actively developed, you're free to suggest changes, and each new revision generally brings notable improvements.

However, there's no need to wait for someone else to implement any improvements you're after, because Pure Data is totally open source, which means that you are free to adapt it and to get involved in it's development, although you do have to be able to program in the language C to do it. Hopefully this article has given you a taste of what Pure Data can do.

It offers a vast range of possibilities for producing sonic and visual arts, and combines media in exciting ways. And given that it's free, there's little reason not to try it out for size! To try to give some idea of the range of sounds available to you through Pure Data's processing and synthesis capabilities, I've created some audio demonstration files which can be downloaded from the links below:.

A vocal sample altered with a granular synthesis patch from Pd-extended. Note the wide variety of sounds that can be achieved with just this patch. This is the wavetable synth patch featured in the article. As the sequence plays, the oscillator waveshape is altered by drawing on it. This is the output from a simple frequency-modulation synthesis patch. The frequency of the modulating oscillator is swept to produce rich timbres.

Randomising the settings on a software Roland TB emulation. Another application is being used as a VST host and to play the sequence , whilst Pure Data is used to alter the settings. The patch used here is very similar to the MIDI patch editor featured in the article. Here one wavetable is modulating the pitch of another which provides the oscillator waveform. Both wavetables can be drawn on with the mouse to alter their waveshapes and the pitch of the sequence. The main Pure Data site. You can download the program from here, and I'd recommend going for the package called Pd-extended , because this includes lots of additional processing objects.

The Community area offers loads of patch examples to help you get going. Here you can find the Pmpd collection of objects for Pure Data , which offer a variety of physical modelling processes that can be applied to audio processing.
