However, external audio signals through the Pocket Operators seem much muted, but the "sync" works like a champ!The Pocket Operators “sync” well with Korg's Volcas, but the Volca synchronization pulse is constant.

I did not have much success "sync"-ing with an Arturia BeatStep Pro or Akai Professional's Rhythm Wolf, Tom Cat, or Timbre Wolf's gate outputs.

The sounds are fun, very electronic-y and demonstrate the attributes of various type of synthesis.
