VividShaper v1.3 has just been released for iOS. The macOS version is currently still waiting for review, but will very soon be available on App Store too.
This version comes with a very nice new delay effect. It consists of two delay lines, which can be configured in many different ways, including as a ping pong delay or a stereo delay. It can also be chained. You can also control which oscillators that should be sent to the delay. This allows for some really interesting sounds. For instance, you could have two oscillators in your patch, where one is not sent through the delay and the other is only sent through the delay.
