Output Gate Only When Note Changes

I have a quantised 1v/oct signal that is coming from an Audible Instruments utils Min output. I’d like to pass these notes to an oscillator, but only when the note is not the same as the previous note. Effectively I want to drop any notes that do not change from the previous note, for example if the input has been quantised to E Dorian, and the sequence is as follows:

E G B B D A A A G

The output will be the following, dropping the second B and second and third As:

E G B D A G

I know I can control the note output using a sample-hold, but how do I generate the gate to trigger it?

you can use a slope detector, id reccomend the one from count modula, that can give an output when a signal is moving/being changed to trigger the adsr that i assume you want it for

ML Quantum quantiser outputs a trigger or gate when note changes iirc?

Perfect. I passed the ‘Moving’ output of Count Modula’s Slope Detector to the Gate of the oscillator. Thank you very much.

Thanks. Using the Gate output of Quantum work, but Slope Detector allows you to change the length of the gate as well which is helpful.
