Title: Patch Randomiser
Post by: toneburst on June 20, 2014, 03:00:02 PM
Sorry for the probably stupid question, but does the PreenFM2 have a patch randomiser function?

Shame. Thanks for the quick reply, anyway.

It could be written as an external tool or be implemented in an editor.

But with FM random patches tend to be very unmusical.

Seems like i'll have to work on that one day.

Could be written internally also.
But it's not obvious.
As 6581punk said,  pure random would lead to 99.9% of unusable sound.

The mb6582 has an interesting implementation- you can choose which sections to randomize, like oscs, modulations, filter, seq etc. Would be interesting if a similar approach was adapted to the preen engine, and would be a good solution to the unusable outcome problem.

That sounds like a great idea. Thanks...   :)

TubeOhms Ambika patch editor has check boxes nxt to each parameter so you can choose which parts you would like the randomise button to effect

Yes, I was thinking of something like the randomiser on the MIDIbox/SammichFM. It does come up with some interesting sounds, though, yes, generally not 'musical' ones, it has to be said. I've just sold my SammichFM to a member of another forum, and the random patch tool is the thing I'm going to miss most about it. Spend many a happy hour creating weird over-modulated SFX and percussion noises with it.

Maybe Xavier [edited: sorry, I got your name wrong - too many forums…]  will roll some kind of randomiser into the editor he's working on.

No sir, than you!  8)

Morph option?

Select two patches and gradually cross fade into another (you would select L:R percentage 100:0 50:50 etc).

I forget where it came up, but one complication for morphing is how to handle the mod matrix.
But an audio cross-fade should work with two instruments on the same midi channel :P

Well, it was more of a "patch load" option. You select two patches, then a ratio between the two and then can preview the result. It would have to ignore some parameters of course.

It would probably create a load of awful noise :)

Usefull thread, thanks all.  :)
I don't have much free time currently, but I'll first finish the Editor then back to firmware with the randomizer as high priority.

and 0.01 increment for p1...p4 please  ;)

0.01 is already commited  ;)

Will be in firmware 1.02 that i'll upload at the same time as the first editor.

Just a short suggestion:

The idea of choosing which parameters to randomize is very good, and could be supplemented with another function: For the operator frequencies, one might have the option to only produce random values which give rise to "nice" frequency ratios, in order to produce more "musical" sounds. (Easy to implement for one carrier-modulator pair, perhaps trickier when it comes to a higher number of operators, I have not really given this much thought.)

You could ensure that all Carrier operators were tuned to the same pitch (or octaves of the same note), perhaps.
