Synth block basics

The power of the synthesizer tool is creating your own custom sound effect—it’s like you’re inventing an instrument! To create one, use the create synth block.

Give your synth a name, like “bleep” or “my sound.” If you click the pen icon 🖊, you’ll open up the synth editor pane, which allows you to fine-tune your effect. Let’s take a look:

❶ Pre-built Effects — Choose one of these to set a starting point for your synth. Click random to get a random effect.

❷ Preview Your Note — Press a key on the keyboard to see how your synth sounds. You can reach higher or lower octaves by clicking on the ◀ ▶ controls.

❸ Oscillator — Change the starting waveform to get a totally different sound ◀ ▶.

❹ Filter — Change the filter effects to process the waveform ◀ ▶.

❺ Envelope Controls — Play with the amplitude and filter envelopes by changing the Attack, Decay, Sustain, and Release.

When you click away from this preview, your synth settings are saved. Click on the pen 🖊 to edit it again.

Make your synth play with a script like these:

Or you can control your synth using beats, too:

Note that you have to add the "load synth" block if you want to use your created synth in a script:
