Are you selling it as a bare pcb or with some components on it already? Anything weird/rare on it? Probably both, but at least bare PCBs. Nothing rare really, but some components needs to be purchased from other than mouser. It's mostly SMD, so it's going to be a medium level SMD task, or if I'll a...

Progue REV2.0 is on the drawing table. Component count so far: 932 :party: I'm hoping to finish this in a week or so, and get it tested in a month. If all goes well this should be available for purchase by the end of the year. The BOM is 90% ready, but I don't have an estimate of the costs yet. More...

Which in my opinion is a better approach for OG re-dos anyways. Agree. Let's make them better, not just copy the same mistakes/compromises/etc that was done 40 years ago. IE. we have better parts and manufacturing, let's use them. That's what mr.Oberheim has done with he's new designs too. But each...

Is the switch for octave backwards? Meaning the legend is correct, but the lowest pitch should be the switch moved to the left? Yes, hence the name "prototype". There's also a couple of wrong taper pots on this proto just because I got frustrated with the shipping delays :-) All fixed of course for...

We had major issues with seeeed - missing traces, missing parts. They were a nightmare to deal with to try to get it fixed - strongly recommend to avoid! I've had zero problems with PCBs from Seeed, but the customer service is nowhere near fluent english. JLCPCB is the cheapest for proto (5-10pcs),...

Any chance of sync via contour as that’s a killer feature?

Filter envelope can modulate osc2 pitch, if that's what you mean? That's demonstrated on the video around 4:40

any chance you would sell a PCB for this?

There will be PCBs available once REV2 is done. Please read my post above.

Walkthrough of the prototype is in youtube:

Hi all. Just an quick update on this. The prototype had just a couple of easily fixed issues and I decided that extra testing is not needed. Also, due to Covid situation shipping times are near ridiculous, so I rather build&test them myself more efficiently. Sorry guys. The next step towards the "re...

I have what I believe is a problem. The voiced detector is always on unless the unvoiced takes over, regardless of if there is a speech input or not. I see it seems like Tekmans works like that as well in the demo, but surely the circuit should work so that theres only detecting/vocoding going on w...

I will tell you a hack though. to save money, you can do a stackup definition that puts all vias on to all layers. this keeps all the drill holes uniform across all layers. it eliminates an extra masking process at the fab. therefor saving a lot of extra work and money. you might not be able to use...

My non-EE opinion is that these things largely vary depending on the actual PCB size. If you can manage to get solid ground plane with 2-layers, I'm not sure if there's a real advantage with 4-layers. If space is really limited, then 4-layer makes sense, especially with SMD components. As long as it...

Nice work! Post some audio when you get to it!

My opinion is that fine tune needs to be max -+1 semitone, if there's a coarse pot. For +-octave switch -type of VCOs you need a "fine tune" of at least fifth, but that's not usable for real "fine tuning". For this reason I added a "Beat" pot for my Progue synth, which is only one semitone from cw t...

just want to share that i recently finished my rev2.1 build, using AS3340 IC, that turns out require some resistor changes on the voice board to make it work. unfortunately this hasn't been documented anywhere, so i thought i'm gonna share it here for those who want to save money and use the alfa c...

Just here to complain about the friggin voice cards. I've only done three resistor values and its taking forever...

I did all 8 cards at the same time and the resistors only took me one day ;-)

double post

I've built one from an old single bus organ keyboard with the MFOS controller. It works as should but there's a couple of points to be made when it comes to these old school designs. You might know this already, so take this as general advice. If you are planning to play tonal western music, in tune...

It's more like SH-101 & SH-9, not TB-303. Fun little synth, but yes, there were some issues with it. Mine works ok. I made this time-lapse of the build:

Such a love letter to the Rogue. Any idea on price ballparks? Not yet, but there isn't anything expensive NOS parts, etc, so it should be decent in price to build. I'm also thinking about doing a small run of "SMD pre-soldered" version, so people with no SMD experience can join too. Through-hole PC...

Hi Janne, Did not find these in a quick search. Do you have a part number or link?

https://www.digikey.com/product-detail/ ... -ND/527076

Maybe its also a keyboard version? with pitch and mod wheel if that lay in your interests? Thanks! The Keyboard version would be lovely, but at the same time, it would require a quality enclosure (like Devin's "WestonPRO2021" Pro-1 clone project) and at the moment I'm not the one that can properly ...

So, here are some details of PROGUE. It's heavily Rogue based with modifications and add-ons. Oscillators are from the Rogue, with add-ons like independent waveform switches, PW pot, PWM with a dedicated triangle LFO, Fine-tune for OSC2 (Beat), and the option to use Gate signal as a sync source for ...

Hello, my SDIY friends! My latest project has advanced to "a working proto" -phase, so I thought I'd share some pictures of it. It's basically a mixture of Moog Rogue and Prodigy with some extra features, all in a single 4-layer 230mm x 130mm PCB with (mostly) SMD components. And since it's SMD, I h...

BTW, last 2 PCB sets for the full 5U -version available.
