Hopping Ratios Preset: How to recreate it?

[mjharding]

Hi all,

The DX7 preset 'hopping ratios' - I tried to recreate it yesterday, using the Mod window and the matrix, but couldn't get it to work.

Is it possible to build it from scratch, or to tweak a different DX7 sound to have the same arpeggiated switching between different coarse tunings?

Are the 'data entry' sliders re-programmable or are they set in place? Couldn't find a way to edit them.

Here are a couple of images:

https://ibb.co/nQgC9wK -> LFO 1 and LFO 2 are controlling the coarse tuning of the 4 OP voices. The other matrix points do other stuff.
https://ibb.co/Zxkg9GS -> the Data Entry sliders with OP ratio. Also the envelopes.

Is it just the DX7 that can be programmed this way? Is this a common feature of synthesisers? If so, what is the technique called, so I can look up more about it?

Thanks.

Hi and welcome to Arturia forums.

There are more to it than the Matrix settings.
In example you mention the modulation envelopes with the images, but they are not used. The Operators envelopes are used in the preset.

Yes. All the presets is a result of the settings anyone can set in the synth.
The random modulation is done by choosing the Sample/ Hold waveform for the LFO's.

What do you mean?
What could'nt you edit?

Many synths have Modulation Matrixes, and LFO's or other things that can create some kind of random modulation.
This preset use random modulation of the pitch.


You can find many informations in the manual. Also about using the Matrix and the Data sliders.

Thanks very much, I am a noob and it was a little overwhelming to try and research the matrix. I appreciate you breaking it down like that.

Your welcome.

Feel free to ask in the forums.

If you are new to synths in generel, then perhaps start with more simple synths.
And perhaps read about  the different kinds of synthesis different synths use.
