Dualchord Expander

[XORadmin]

LFO can be routed to the AMP of the individual waveforms?  

Yes

Individual AMP values can be written/programmed directly as parameters by the Nerdseq sequencer?

Yes

The Nerdseq internal FM is pretty cool, though a bit hard to set up, because it is stretching across the voices and tracks.

It's not easy, FM never is. But you can completely set it up without leaving the screen (except if you want to add envelopes). The UP/DOWN buttons guide you to Operators 1,2,3 and 4.

I’m a bit spoiled though from the Essence FM which has a very good FM programming interface and workflow.

That is a dedicated FM synthesizer with it's own big screen as a main product and I don't really think that it is comparable in a way.

Another Idea would be to enable AMP modulation using other waveforms as inputs, to utilize what’s already in there and to get a vast array of wave shapes out of it as an oscillator module.

Worth to experiment with that.

Maybe it would be a good idea to have a slope parameter in the inputs that’s configurable to smooth the parameter changes (similar to glide which is used for pitch) from the Nerdseq going directly to the waveforms? Then the parameter changes would result in small “Envelope” sections in the transition phase. For doing chord type evolving sounds this would also be nice to do changes smoothly in the sequencer synched to the tempo in a more linear fashion than LFOs or piecing LFO sections together.

That could be something for the future.

For now, it is what it is. It's 'oscillators' with some nice extra features. No-one but me played with it so lets see first what users will do with it. I am not planning to make a FM synthesizer add on for the dualchord as it would involve much more development time (think about the synth itself and the user interface etc) to get this nicely done. It might be technically possible but maybe also not. For now I concentrate on the new NerdSEQ firmware release which got to be there once the first Dualchords arrive.
