preenfm2 and preenfm3 / Re: About Save Functions
« Last post by Iapetus on November 21, 2021, 11:40:31 AM »
Following on my previous post ... why not?

I really struggled to get the Save function working. This I realised was the limitation of a thread bare manual and lack of tutorial material to dive into. Figuring that whilst the interface may differ slightly, in essence PFM3 is PFM2 I started to read the (more in depth) PFM2 manual. That resolved the issue - first you create Banks to store presets, Banks to store Mixes. Once I had that figured I was able to create and save.

My next matter is getting Scala scales loaded. I haven't tried this yet and there's no urgency yet.

I'm just super impressed with the design of the PFM3, it's just so good, so full and rich. I can't find anything I don't like - I think Xavier has created a classic synth to rival all the big names. Amazing.

Still familiarising myself with the menu system on the PreenFM3. For the most part - sound design and layering, mixing etc - it's quite straight forward and intuitive. I think it's a real nice system to get around. The only thing I'm not clear on is the Save functions in the Menu.

I've yet to try these thoroughly. I couldn't figure out yesterday how to create a new Bank or name a Preset. No doubt I'll resolve that issue by the end of the day.

Still, am I correct in understanding that

MIX saves all 6 Presets with everything that is allocated to that mix eg. pan, volume, reverb levels, assigned midi channels etc etc?

PRESET saves the actual edited sound design (making it available to load into one of the 6 slots in the mix section)

SEQUENCER saves a sequence (presumably)

I am also wondering...

- if a Mix contained a Preset, or sound that has been edited but not saved as a new Preset will the saved mix reload the Mix as it was saved or will it load the pre-edited Preset/sound?

No doubt I'll resolve some of these questions over the next day or so as I test out and explore the device but it would be nice to hear from others.

Are there any shortcuts or combination button actions that I should be aware of - the less obvious stuff.

Try the 2A version. It doesnt hurt and will work.
If it doesnt contact me over email to resolve it. There can be something wrong with the jumper configuration.

I dont have any plans for PFM3 to go to eurorack. Its too big for that. And it kind of doesnt make sense at this point.
If the firmware is more developed and there is time for usable CV inputs that really brings new things to PFM3.

With PFM2 it made the unit really fun and usable with CV inputs. I really still enjoy what I can do with it and how fun and good it sounds.
PFM3 still needs some time in my head. Need to get to know it more and what it can do.
Having 6 outputs then it would need a lot of CV inputs to make it fully usable on all the outputs.

Just moving the PFM3 as it is to eurorack is taking up a lot of HP and its not really functional with other eurorack modules. Output it line level etc.

So it a No on my side at this point.
preenfm2 and preenfm3 / Appropriate power supply for PreenFM3

I just acquired a Preen FM3 via Van Daal (excellent service if you're interested). I'm currently powering via the supplied usb cable but I much prefer a proper power supply.

I have dozens in the house but none of them appear to work. Before I buy something can someone confirm what I need. I'm UK based btw tho that shouldn't make any difference.

I assume a 9v centre positive but what m/A? I have a 750m/A plug and that did not power it up. I have a 2 Amp plug but I'm wary of trying it incase it is too much.

Hope this makes sense. Thanks
preenfm2 and preenfm3 / preenfm3 Eurorack (maybe DIY retrofit?)

I will immediately get a preenfm3 once it is available in eurorack format.  Well, if it ever happens, that is.  I don't even care about having CV input sources, the midi functionality is great and i could just have a CV to MIDI converter for stuff like that.  All I want is the eurorack format (the formfactor).

I don't know if VanDaalElectronics has this planned (like with the preenfm2), in case there is some information on that, I would like to know.

I thought I could just retrofit it myself.  My first thought was that I could just make a custom front panel with inputs and outputs on the side or something like that.  I would reroute all the inputs to the side and to (mini) jacks and trs midi jacks.  Well that is a lot of cables.  At least 28 if I counted correctly.  So I thought I could just print a pcb myself, which i would mount on top of the section of the preenfm3 pcb with all of the connection points for all the jacks and midi and usb, with double male pin headers (or whatever they are called).  This pcb that I would print then has some ribbon cable attachment points, which I would then connect to another custom made eurorack module that just consists of the jacks for midi, usb and audio.  The only other thing I would have to worry about is handling the DC power conversion, but I would handle that on the same custom pcb.

The thing is, I would need the exact measurements of the preenfm3 pcb, so that the pins headers line up.  Afaik, David doesn't publish the files for the pcb of the preenfm3 (which is totally understandable).

Is my idea viable?

I am not very well versed in DIY stuff yet, so please tell me if this is a stupid idea.

[Check the attachment for a sketch of what I mean.  I misspelled "multiple" as "multuple" hahaha]

preenfm2 and preenfm3 / Re: Question about encoders
« Last post by Xavier on November 14, 2021, 11:42:15 AM »

The Encoders i know are PEC11R and PEC12R.
PEC11 (metal shafts) are a bit more rigid.
Also it's possible to remove the detend for ultra smooth usage (easy to find tutorial on that), but it can be more difficult to select specific values or just move 1 step.

Is it for a preenfm2 or 3 ? The size of the shaft must be 5mm more on the 2.

Oh, sorry about this, just saw your post, have not received the notification about it.
I've followed the picture and it seems that the pin numbers on the board, does not match the number on the MIDI sockets...
After swapping the wires on the connector, everything works fine.
Weird for sure, but it works, thank you very much!
preenfm2 and preenfm3 / Question about encoders
« Last post by hitachii on November 08, 2021, 11:40:15 PM »
Hello everyone,

The encoders that came with my unit are a little stiff. I've been informed elsewhere on the internet that most encoders can be swapped out for other encoders. Assuming that this means as long as they're the same type (linear, quadrature), and of course, if they come with a push switch.

If this is true, I'm looking for recommendations for encoders. Ideally they would be the smooth-turning type as I'm a big fan of Elektron's encoders though I've heard that those are 'endless potentiometers'. Otherwise I own a single switch-encoder from the store Microcenter which turns with a very light touch, though they're about $4 apiece so any cheaper suggestions is invited.

Any suggestions or education is appreciated. Thank you!

Always nice to see a new preenfm3.
Thanks for sharing  :)
