Just wanted to chime in with Hawkeye here. This looks like a really useful module! Of course as we all know - the risk with eurorack is modulitis - just need to add another O&C for utility functions, the new shine module from Mutable or 4ms or Make Noise or what have you...
-
I was going to keep working on this on my end too, but demands from real life, work and family seriously got in the way. Plus, there’s always the risk of getting distracted by other geeky things near and dear... there’s always the risk of running into the next “ooh shiny” distraction.
That said, it needs some thinking about the 45degree OLEDs - it’s not necessarily practical; having a base board for displays, LED rings and encoders plus keys would make life easier. Now that MIDIphy has standardized on keyswitches and LEDs it’s a given to look for something in that style. Also, I saw a game controller joystick hat in some rendering of the upcoming BLM... That would be a nice to have for vector synths, quick setting of time/level envelope points and what not.
On the MIDI devices end a few difficult and rare synths have gotten editor support. The Ensoniq Fizmo has an editor and I expect to see something for the MR Rack soon-ish. Work is on-going for really odd and difficult things like the Technics WSA1. Everybody and his dog has made editors for the Alpha-Juno or Ensoniq ESQ, the cool thing would be the ability to support oddballs that are less represented. However, it’s way easier to prototype these things on a PC/Mac style platform first. Just controlling my MKS-50 or the Casio CZ-5000 or other synths with a more basic tone generator would make me happy. Shooting for the Kawai K5000 or the Yamaha FS1r isn’t as easy.
Here’s hoping for something as well as more time to spend moving forwards!

Snagged a kit, my old LEDs with a diffusing plastic spacer are too dim. Gotta give the old box some TLC! Wonder which synth to place it on, or it I have deskspace left after my Hyper-7 mechanical keyboard excess?

Mmm, nice tune! It started a bit like some track by Ünn (Über Normalnull) the took off. Good work!
-
Nice song and video! Typical that regulation kicks in as soon as something becomes mors mainstream. The free and exploring time is usually more fun, but safety has its own place. Hopefully it’s back to soldering this autumn, I need to service my synths and catch up on the backlog

A single USB won’t give you that much wattage to play around with. Plus, the USB power itself can be assumed to be quite dirty if derived from a cheap switcher shared with computer components.
Your best bet would be to derive multiple voltages from 9VDC, or even 9VAC if you need bipolar voltage and no fancy solution for -12V from +9VDC (inverter or DCDC converter), then use multiple 78xx or 79xx with the addition of a 78/79xx compatible switcher for the digital VCC and OLED VCC.
The Preen FM2 OLED saga is described here: http://ixox.fr/forum/index.php?topic=69159.0
Basically, shielding works. Separate power will also help.
-
Try to power the AINSER from a separate, dedicated PSU. Or try to power the display from it’s own PSU or regulator. Some older systems tried to keep these issues under control by providing VCC for digital stuff, well regulated V+- for analog electronics as well as AGND, plus a separate dirty DGND for digital, switching stuff.
The Preen FM2 needs some care with shielding the OLED coil, or replacing it on the OLED PCB with a quieter model, that’s also worth investigating.

Ditto! Please out me on the list.

Excellent video! Listening to it is very calming, it’s like an ASMR version of DIY
-
Awesome videos! This is going to be a fun build once I get my paws on one of those.
Both the build video and the SMT video are useful. IDK why people are afraid of SMT so anything that minimizes this anxiety is good
Well done!
-
Ah well, the other guys are trying but I trust MIDIbox, TK, Andy and Peter so a LoopA Will definitely fins its way into the workflow AroundMe these parts
Well done!
-
I'd be down for 20 of those post for some tinkering
-
Nice work!
I like how layered it sounds
Cheers!

Old-school and nice! The Strymons make everything sound less ProTools which can be a good thing ;) This summer is crazy busy, but it's nice to stop by and see that people still manage

Nice one!
Greetings from Stockholm!

There's nothing magic in the CEM3372. Some other CEM chips also support pole switching. Some, like the CEM3378/79 don't do it as easily. Better leave them for spares for the good old stuff like Chroma Polaris and such.
If you want to see pole mixing done with readily available components you could take a look at the 4 Pole Mission Shruthi. The Ambika didn't realize a full version of that due to component count/cost, but it can certainly be done.

Nice work Andy! Where does the Alps Jog/Shuttle go for those of us who like to use one of those for scrubbing and MMC controller action? Can't lose either way, since the normal jog surrounded by switches seems like a nifty interface element, just wondering.
Cheers,
Johan

Hint, the Tayda code is often posted in the DIY section at Muffwiggler if you're reluctant to enter the time sucking world of Facebook p. At the moment it's the same as a musky brand of electric vehicles named after a well known pioneer in AC electricity.

I use IntelliJ a lot at work these days, as I *gasp* turned out to be an occasional Java hacker. It turns out that JetBrains has a similar IDE for C/C++ out - https://www.jetbrains.com/clion/ and it looks promising so far.

Nice! JP-8080 is underrated by many. Think twice before selling yours.
-
Evolver, eh? I've been looking at Sequential/DSi Stuff to go beyond the VS, maybe I should act on it? :)

Great jam! Always nice to hear some dub drops and SID Sounds
-
Yay! Great music again! Dawless and nice. Nice to hear that you enjoy the JD-990, I guess I should take a look at a Dominion to even the score
The Polivoks filter addition was a nice touch to further warm up the digital pads!
-
I think that the Cirklon (and the Nava 909 clone) are using Cherry Mx. Those are nice and it's easy to get keycaps in any size and color. Plus, you have lots of different switch types with different actions, plus the Gateron clones to pick and choose from.
Anyway, you might want to avoid the more clicky variants.
What parts are they and what can I do with them?

Aah, quite the variety of modules.
The first one is a GM5 USB to MIDI Interface. This board only has 1 pair of MIDI in/out, the jumper can be used to connect a further 4 MIDO io pairs.
Then we have a pair of LPCxpresso boards for the 1st gen LPC1769 STM32 microcontroller. This is a variant of MBcore 32. You dock these to a baseboard and voilà.
Then we have a Microchip dev board that’s not normally a part of the MIDIbox ecosystem.
Followed by a Pic18F452 MBcore8 for older projects like MBsid, MBfm and the like.
Last is an AoutNG - an 8-Channel 12-bit DAC board for analog outputs. This is mainly used for the generation of up to 8 CVs at 1V/oct. These can be unipolar or bipolar. Other scales are available in the MIDIbox software. These can drive analog VCOs, VCFs and such.
