Synopsis

Overview

A quick look at some very basic Pd concepts. We explore connecting together a metronome and random number generator, playing a sinewave oscillator, scaling a signal using multiplication and introduce some simple GUI objects.

New units used

• slider: A GUI slider, horizontal or vertical with settable range.
• toggle: A GUI object to switch things on or off , sends a 1 or 0.
• [metro]: Generate periodic bang messages.
• [*] Multiply two float messages.
• [+] Add two float messages.
• [/] Divide two float messages.
• [random] Generate a random integer.
• [mtof] Convert MIDI note numbers to frequency (Hz).
• [osc~] Audio signal sine wave oscillator.
• [*~] Audio domain multiply.
• [trigger] Sequence evaluation order of message events.
• [loadbang] Create one bang when patch is loaded, for initialisation.
