AudioKit 5: Sequencing effects

I am trying to figure out if it is possible to add effects to a new track in the sequencer just like you would with a instrument.

So far I haven’t been able to figure it out based on the docs, but the idea is to be able to sequence parameters for a selected effect just like you would with midi note information such as velocity, length and pitch/note for AudioKit instruments. Say if you wanted to sequence a low pass filter; you would have access to sequence the cutoff frequency and resonance etc.

Any ideas if this is achievable with AudioKit?

Thanks in advance.

You could represent the parameter changes you want to sequence inside MIDI events, add those events to a sequencer track, add the track to a sequencer and connect the sequencer track to a callback instrument. The callback instrument would change the low pass filter's parameters.

So the outline of the process would be:

SequencerTrack -> Callback instrument -> Low pass filter's parameters

It might not be an ideal solution because you would be calling a Swift function from the DSP and back into the DSP from Swift, but it's the only solution that comes to mind without writing your own custom DSP code.
