PreenFM3 Questions

[Xavier]

Thank you, .dxf would be perfect!

Let me know if the attached dxf work.

[Megalomidiac]

Thank you, they work.
But I did the work by myself in the meantime, it's the kind of work I like

I have another question:

On the top side, there is marked a circle that I think is left from the PCB design, a little screw between the potentiometers. Will this screw make trouble or can I ignore this?
It made a little failure in the 3D Print, if you make a 0.3mm first layer, there will be only 0.1mm layer above this hole.

Yes that's the goal.
There's a led just bellow so if it's thiner the led will  be more visible through this little circle.
It's not essential

hi. just a quick question for a FM newbie. will this make it more like a dx7, hence importing old patches to create similar sounds? great work and i'm looking forward to the preenfm3.

PM with feedback please

Available in the v0.91

Don't expect a all new universe of sound, but can be interesting in some situation.
So it's a phase modulation feedback with a DC offset removal algo not to shift main frequency of the followin FM op.

For each algo the operator with feedback is visible in the UI, and can be changed with the "Fdbk" encoder.

Hi,

Thanks 

preenfm2 and preenfm3 are not good DX7 emulation with or without feedback.
DX7 import can be usefull to browse new patches and use them as a starting point of a new preset creation by adding pan, some modulation, effect, arpegiator.....
Or just after a DX7 import, go to the randomizer and only add a bit of "Soft modulation" without touching anything else, it can give good result.

But don't buy a preenfm if you're after a synth that sounds like a DX7.

If you want to explore FM synthesis with a flexible hardware synth, go

Hi

What are the dimensions of the 3D printed case, please?

Apologies if I can find this out from the files but I don't know how. Also don't have a 3D printer of my own so I would have to find a service to print it for me. Anyway the dimensions are important for planning how I would fit it into my setup with the very limited space I have.

I also might just wait and see if Van Daal Electronics produce an assembled version as I'm not very confident about soldering.

Hi,

I would wait before ordering a 3D print from a service.
Wait that someone with a 3D printer at home, confirm it works well and maybe improve the model.

I've just updated the page with a new model :
https://github.com/Ixox/preenfm3/wiki/3D-Printing-Enclosure

The preenfm3 in its case is around 20.5 * 9.5 cm.
Height is 4.5 in the front, 5 cm in the rear.

Weight of model B is around 100g if i remember correctly.

Thanks Xavier

Metal case is also in production. proto Should be available in few weeks.
