Hi all, I'm currently working on a project and I wish to do automation on the kick so it goes up in pitch. (Imagine a kick roll).

The issue I am having is any pitch shift vst I try when I apply the automation it does a weird resample out of timing effect which just doesn't sound smooth and very unappealing.

The file is a drag and drop wav file so I've not put it in a sampler.

Any help is greatful.

If it is just a sample: put it into NN-19, Grain or Mimic and pitch it to your liking. Even putting it into Redrum and automating the tune should work.

Can I do this without having to relay the full kick drum channel? As it'll go from been an audio sample to midi notes or am I mixing things up here haha.

What you're talking about is pitch envelopes for audio, and Reason can't do this. I very much wish it could! I think you could maybe put Neptune on it and just automate pitch on that (making sure to disable key tracking and scale correction).

You could also drag the sample into Mimic and then make sure you're in Advanced mode, not Tape. So that the duration of the sample will remain unchanged while you automate in a pitch bend.

In something like Live you can just automate the pitch. Wish we could do that in Reason too. Would be a fantastic sound design tool.

Both Grain and NN-XT has a pitchbend range up to 24 so that could probably be useful here.

Mimic is best for this, just import sample and set stretch type to Melody, also don't forget to set root note. If the octave is set really low like a C0 C1 etc just move it up to the middle like C3 for example, A-1 to A3 etc etc, leave the tune alone

If you want to do the old Fairlight CMI drum roll/pitch rise/fall, it goes in half steps. On the CMI you’d do this by holding the transpose key on a sample on Page R and the key would ‘auto-repeat’ causing the same to retrigger quickly with each semitone change up/down.

If you’re talking an audio file on an audio track, I’d just cut each kick of the kick roll (in slice edit mode it’s super quick) then use the transpose on each slice to create the desired pitch change. That way you’d have precise control over how much each step is transposed so you can hit a specific target pitch at the end of the role, if necessary.

This approach is probably as quick, or quicker than loading the same into another instrument just for this one effect I would think.
