Me three. I can only but concur everything said above. This module is the prime example of the level ae modular has reached over the past years, both in built quality as well as functionality.

Just ordered - fully assembled (sorry, no soldering for me) and black panel !

Howdy all,
Just an update to say that this is now officially on sale!
There's 9 available (across both sites, so i'll be juggling stock as best I can). Interested to see which panel is most popular I hope DIY kits will be preferred by most as we're having a small heatwave in the UK and soldering isn't very appealing!!
do you think there is much scope to process audio signals with this ?

Hmm, it might be pushing what a Pico can do, I'm not sure (not much of a programmer myself). One of the scripts provides a basic square wave audio output but generally speaking i'd say its much more suited to CV manipulation

do you think there is much scope to process audio signals with this ? To be honest, i think there really is with the Pi Pico. There are some audio scripts around already. It's basically the Arduino Nano on BIG STEROIDS, so as the Nano is capable of some pretty great sound sources, the Pico is def as well capable. But...... : The AEuroPi environment is based on Python. Which I love because Python is pretty easy. But Python is slow, which is a problem for audio manipulation/generation. So the problem is not the Pico itself, but Python. However, the Pico can be programmed in C as well, which is about as fast as it gets. But you need some real programming chops for that, and a completely new basis (not the same menu, or a reprogrammed version in C maybe, etc..). Not something trivial at all. I really believe we'll see some great Pico-based synths coming years, just like there are some great Nano based ones (looking at you, FreaqFM). There are two fast, parallel CPU's in the Pico, and above that, IIRC there are 8 supersmall, lightning fast 'mini' CPUs (which can def generate square & saw waves, there are projects that do it already). So plenty of hardware for a good synthesizer.

FYI Rory pushed a EuroPi firmware update over the weekend which includes a bunch of improvements and a couple of new scripts! One, the envelope generator, was actually sneakily teased in my launch vid because i was rocking a few pre-release scripts at the time
In terms of updating, the easiest way i see is to use Thonny to re-install the micropython-europi and micropython-europi-contrib libraries. This should pull in the new version, but probably will overwrite the custom AE files. I've therefore merged my existing amends with the new versions of those files and hosted them here: github.com/fauxcyrillic/AEuroPi-0.9.1You can download calibrate.py, europi.py, harmonic_lfos.py and master_clock.py, open each one in thonny, then save each of them to the pico, replacing the existing version of each file in turn. I tested this on my own module and it worked fine Future orders will receive this latest firmware, along with the two people who ordered pre-built modules, because I built them both today (should be hitting the postal service tomorrow)

Wow just wow, that PAM script is just ridiculously packed with features. Now I only need the time to install the new scripts and have a go with them. Is there a link somewhere to the proper procedure to do this? I've never installed scripts on a pico before. But I guess it can't be more complicated that say programming an arduino. Edit: nevermind I found the programming instructions on your github page. Cheers.

If I ever move out of the hamlet firmware I might try updating!

Hamlet is my most used script so far, but PAM looks like another very potent script, not a replacement because although they can do similar things they are quite different.

FYI just discovered that the Pam's script is pretty big and looks like it's sapping a bunch of memory when loading the main menu, meaning the last couple of scripts in the list don't get loaded to the menu at all. I'm figuring out a way round this with the help of Rory's discord. Just something to watch out for if anyone was planning to try the upgrade

some fantastic reviews how can one resist and phew there were some left so I'd better warm the soldering iron!

Thank you!! I’ll get it sent out as soon as i can, i normally print the postage at work (who has a printer at home these days??) but i’m not in the office until tuesday so will see what i can do to get it moving sooner.

I've done a couple of parcels recently using the Royal Mail's collection service along with 'bring a label' — if you tick the right boxes when arranging the collection they will bring a printed label to your door; no printer required … I don't use the collection service very often, but sometimes it's quite convenient! (I've not trusted them for Lectronz orders yet — I wouldn't want the IOSS stuff to be screwed up and have the customer pay double VAT etc.!)

Update with the uf2 file works like a charm.

Mine came in the mail yesterday! However it will be a few weeks before I can find the time to build it.
Is there anything about the build that I need to watch out for?

Post by pt3r on Jun 29, 2023 6:08:38 GMT
It seems like a very straight-forward build. I always prefer to assemble/testfit the module before soldering the pots and connectors, switches, and whatnot to make sure everything lines up correctly before committing those last solder joints. And of course make sure to respect the polarity of your components but that goes without saying.

There's nothing particularly unusual, the only thing to watch out for is the buttons - they have these little plastic lugs on the back which they wobble back and forth on, so getting them to sit straight before soldering them can be a bit tricky (i taped them in place and carefully made sure they were as straight as possible) namke pointed out these are supposed to sit in little locating holes on the PCB but i didn't spot that so there aren't any locating holes You could do what he did and snip the plastic lugs off, that way it will sit flat on the PCB and be easier to get straight (and the pins will actually come through the board so easier to solder)

I have discovered a thing in PAM's workout; the generated gate signals are only half the voltage of a normal gate signal, they are not 5v but 2.5v. Hamlet does proper 5v gate signals. will have a look at the code/documentation to see what I'm missing
edit: my bad this is set in the amplitude setting per cv output, talking about a deepdive script.

Phew! glad you figured it out. I haven't really dug into the code of that script

Quite honestly it is quite overwhelming to start with IMO, hamlet is a much better (i.e. more instantly musical) choice, my 0.02 Edit: Just to be clear, PAM is definitely super powerful and in a league of its own, but it needs a whole lot more configuring/menu diving to get anything interesting going on.
