Loop

Last updated 1 year ago

The Loop Menu has just one entry, "Add".

It is a special case programming wise in that it drops in two blocks - a Loop Input and a Loop Output. These blocks are used to reliably make a feedback loop in your design. They introduce 1 sample of delay.

When you first drop in these blocks, your mouse pointer will be moving the "FB Out" block. Click to drop this in place and continue editing.

Notice that the "FB In" block has a white outline indicating that it has a control panel.
