Unison after FM

Double checking: it’s currently not possible to apply unison to a FM waveform, right?
(without resynthesizing the preset)

Should not be a problem if you use one oscillator to modulate another. You apply unison to the carrier (modulated oscillator).
However, if you use an LFO to fm an oscillator, the results is going to be very bad.

Thanks for your reply. I didn’t manage to get it right yet, so I will try to elaborate the question.


This is a basic FM waveform. It sounds like this:


When I apply unison to the carrier (8 randomized voices, 20%), it introduces a weird phasing effect.
(Please correct me if i did the wrong way)


If I resynthesize the base preset it to a single oscilator instead, and then apply unison. I get the sound I’m looking for. This is also how unison sounds in FM-8 or Massive.

Is it possible to achieve this without resynthesizing?

yes same here if i try this.

maybe @Tytel wants to take a look at this.

Is it really a bug? I would kind of expect the oscillator modulations to happen after unison, based on the way the UI is laid out. But I wouldn’t mind the option to have unison after the modulations.

That’s weird. I will try this later on as well.

FM is done per unison voice before adding them together so e.g. the unison voices that are tuned down will sound different than the voices that are tuned up and then are combined.

The order you’re looking for doesn’t really make sense with ‘live’ FM. Preprocessing an FM table is the way to go for what you want (looks like you already did that)
