Value of type AVAudioUnitSampler has no member destinationForMixer

The sequencer playback position slider is not updating during sequence playback. This behaviour is different from the original Objective-C version. I am unable to say if this is related to the Swift conversion, the use of AVAudioSequencer from the Swift runtime, or something else. I'm reporting it in the hope that something interesting will surface.

I ran both versions on an iPad, and after noticing this in the Swift version, I printed out the value of _sequencer?.currentPositionInSeconds when the property is accessed. Seems the sequencer position value is not being updated at all.

Changing playback rate of sequencer wasn't working.

Fixed by replacing the one line in func setSequencerPlaybackRate with:

self.audioEngine?.sequencerPlaybackRate = sender.value

(instead of: self.audioEngine?.sequencerCurrentPosition = Double(sender.value) )
