SEIDS walks through the full vocal recording workflow in Logic Pro, from setting up your input to comping a final take from multiple performances.
First step is picking the right input: create an audio track, then match the input to whatever channel your mic is plugged into on your interface. Check your audio settings if you're not sure which device is selected.
If you're on a condenser mic, phantom power has to be on or you'll get no signal at all, a common early troubleshooting trap that looks like a bigger problem than it is.
For takes, SEIDS sets up a cycle region and hits record repeatedly, capturing performance after performance without stopping. Logic stacks every pass into one take folder automatically.
