PreenFM2 / Re: any way to select timbres via midi?
« Last post by Xavier on May 30, 2019, 02:44:59 PM »

I'm thinking also about adding a midi channel (modifiable in the settings) that would correspond to the current instrument.
That could be usefull.

PreenFM2 / Re: Is it possible to connect a 12v battery?

A 12v battery would make the 7805 (5v converter) super hot.
9v is the maximum you should use.

Yes it can work with up to 30v but only if you need very little current output.
With the preenfm2 9v is tht max if you don't want it to get toot hot and die.

I'm trying to understand exactly what you need here.

I love this synth, but I find jumping between patches and timbres to be the most cumbersome part of working with the preenfm2.

So for timbre :
A new midi CC whichi accepts 4 values (let's say 1, 2, 3, 4) and will change the current instrument of the preenfm2 (display).
Did i got it ?

You also talk about patches ? What do you mean ?


I 100% agree. Any update or progress on this? Also loving the Preen but I also would love to be able to easily switch between Preen presets with a midi controller foot switch so I can seamlessly switch presets when performing.

Kelanimal, do you want to switch between preset (bank) or between the preenfm2 4 instruments ?
For preset, the preenfm2 responds to control change and you can also specify which bank

Can you give more info on how you would like it to behave ?
Maybe let me know an other synth that works better.

Also, I'm still confused about the envelops. Is it possible for a patch to be just one shot (length controlled by envelop) instead of looping (sustains while key is pressed)?

Arrk 0 Lvl 1
Decay 0 Lvl 1
Sust 0 Lvl 1
Release >0 Lv 0

Not sure i understand your question.
While the key is pressed operators enveloppes remaines on the "Sust" step.

PreenFM2 / Re: creating and saving combos
« Last post by Xavier on May 30, 2019, 09:13:41 AM »
I just did the described procedure (firmware 2.09a) and the combo did not show up after showing "in progress, done"

Just tried and yes there is a problem. The size of the created combo is wrong and so does not show up in the list.

I'll try to fix that. In th emeantime use the bootloader to see your UsbStick on your PC.
Backup your pf2 folder.
Then you can copy your existing combo (*.cmp) and change to the name you want.

PreenFM2 / Is it possible to connect a 12v battery?

I have a power supply with 12v output.
Do I need a voltage reducer? which one? I'm lost

https://es.wikipedia.org/wiki/78xx
in the wiki there is a table that says in 2,2v-30v

Glad to hear I'm not alone. I'm controlling the preen from a keyboard and sequencer setup, so I find that when I want to get to the panel to make edits, I end up doing more menu diving than I'd like.

I don't have the coding skills to make my own custom firmware, but I'd be willing to pay (I'm a struggling musician, so within reason  ;)) for this addition.

also, if anyone has any ideas on this one that I've mentioned in another thread: the ability to save changes to patches quickly. This seems like a bigger fish to fry, but I run into this problem all the time - my sequencer calls up 4 timbres, I edit some of them and yet to save them, I need to navigate to the program and bank manually, or save it as a new patch. Wish there was some sort of buffer so once could update the existing patch. I really like to fine tune patches as I'm working on tunes and this really slows things down to a snail's pace.

These are problems that people only using only the front panel probably wouldn't run into. I'm curious to hear from those who use the PFM2 in a larger setup, sequencing with external gear.
