Re: PROGUE - Analog mono synth - AUDIO DEMO

This sounds really amazing and I would love to build one. Obviously the front panel is pretty full, but if the enclosure ends up being bigger, I would be interested in the High Pass filter being sweepable, if not voltage controllable. It would really enhance the performability of the synth and woul...

Re: PROGUE - Analog mono synth - AUDIO DEMO

The boards have been ordered and in the meantime, I made a collection of my dawless jams with 5 proto units. Enjoy! :sb:

Re: diy partial-kit frustration rant

It is a simple way to look professional. But it doesn't help people when building. In 99.9% of the case you just say ohm, tolerance and power rating and it will be easier for everyone to source their components. Well, for through-hole I'd agree, but for SMD it's not a "bend those 5MM leads to fit 2...

Re: diy partial-kit frustration rant

Last, if a designer write the exact partnumber of a SMT resistor in the BOM, it is kind of crazy. It means he might only test his modules with this one and doesn't want to be responsible if another PN doesn't work, but it also means that he doesn't know what are the important specs on the resistor ...

Re: Kijimi General Build Thread

Assuming competent soldering skills and equipment, how long is it taking everyone to put this together? Are all of the PCB components available from Mouser / Digikey? I'm thinking a DIY Kijimi might be fun to get me thru the rest of winter... I'd say 8h x 3-5 days. Most of the components are availa...

No I fully understand. I work in software, you can make new products or fix bugs. But b) leads to c) customer service and dealing with returns. I sure as heck can get paypal to refund a panel/pcb set if the parts aren't available. But you must realize that if the designer has to be accountable for ...

Re: diy partial-kit frustration rant

For some builds the time spent on sourcing exceeds the time spent on building. ..but it's not the worst idea to re-enter the BOM every couple of months to see how the stock looks. Hmm.. You all realize the fact that it takes the same amount of time for the builder and the designer to go through the...

Re: diy partial-kit frustration rant

The other side of the coin is that there's no way for the designer to know what parts are going to end up obsolete. I'm pretty sure that none of the diy kit designers are deliberately making their BOMs hard to source. It's just that there are SO MANY things to consider while designing a module, so a...

Re: Matching Transistors

Moog standard was +-2mV, which usually is what you get straight from the manufacturer if you buy "on-tape" transistors (same batch). Choose one to be the "compare to" transistor, and just measure 100 or more. Remember to let it stabilize, do not touch it with your hands for 30-60 sec. Write down the...

Re: MFOS 12v power supply.

The power adaptor (wall wart) has to be AC, not DC! The ww1, ww2 -points orientation does not matter, because it's AC. If you didn't understand the paragraph describing which is which, it just states the fact that you should use ISOLATED POWER JACK (DC JACK) to be sure that the DC JACK metal parts d...

Re: PROGUE - Analog mono synth - AUDIO DEMO

Update: The initial release date: "hopefully by the end of the year" didn't happen due to my stupid PCB routing mistake. Also, we had to make slight adjustments to the PSU section (DCDC converter related), which is tested already. I also added some modulation options ('cos why not?) so that that ext...

So what does the MW/AT switch do.

Does it control the amount of osc/vco mod from the internal LFO?
Yes. There's an internal 2-channel midi to CV -converter: one channel for the 1V/oct osc pitch tracking and one for "LFO -> osc/vcf amount" which can be controlled via midi modwheel or aftertouch.

Re: PROGUE - Analog mono synth - AUDIO DEMO

Quick update: Digital section (=midi2cv) has been tested and the firmware is in development. One simple (&stupid) PCB mistake forces me to order proto PCBs once more, but while doing this I can add a couple of test points and other handy add-ons to the main PCB. I'll also test build this once again ...

Re: PROGUE - Analog mono synth - AUDIO DEMO

Hi! Since I have multiple proto units fully built, I wanted to test them with a multi-channel midi2cv unit for polyphonic playing. There's no auto-tune, so it's a bit of a challenge to get them in tune, but I'm pretty happy with how they sound. Makes me wonder if there should be a PolyProgue someday...
