Hi! Power to the MIDI controller you can take with the main board +12V and -12V. I left the only stabilizer + 5V supply for MCU and DAC. If you look at the circuit, I think it's all clear. :) Regards, Ensure Sound

Moog Prodigy clone DIY and MIDI CV Hi All!!! :phat: The promised video demo of my Moog Prodigy DIY clone: 1kZmtsE_KL4 Regards, Ensure Sound

:nihao: :nihao: :nihao:

Hi All! :P My Moog Prodigy DIY clone ready: Demo video, coming soon... :phat:

Good work!!! :supi: :supi: :supi: :phat:

@StormB Great idea, to make the Prodigy in the classic case! :supi: I look forward to completing the project, photos and samples! Best regards, EnsureSound

I prefer the J112. Recent experimentation and tests showed the best result. And the stability of the oscillator.

For all, If you have any questions regarding the Moog Prodigy clone DIY. Write to me in PM, which would not be confused. Common themes I try to discuss here, and immediately informed of any observations. I find it easier to quickly answer your question. Then there is no information chaos. I'm...

For Protonstudio, If your "pulse wave OSC1" is stable, then nothing changes. This change is beneficial for the stable operation of the OSC1 pulse wave. If there is a problem with "pulse wave OSC1" in this case is necessary to replace the resistors. To avoid confusion further, check your...

I recheck wiring guide. Adjustments guide I posted here on the forum...

Upload photos of your Prodigy! And samples!

I'm very happy for you! Finally all turned out! :phat: :phat: :phat: What potentiometers is not correct? There are errors in the wiring guide? I have to check it out... :agent:

@Binaural It applies only to those who have purchased, unpopulated PCB. Your PCB has been carefully tested and calibrated before shipment. Of course I can not rule that you need to adjust the "TUNE" of OSC 1 and 2. After the final assembly... Regards Dmitry

Excellent! Everything worked out! :supi: Regarding the R41 and R48, wrote Brother303 above.

For Brother303. It is possible to use such capacitors:

Corrected BOM for MIDI-CV converter (R40):

R40 for MIDI-CV convertor 2,2K

For those who are building Moog Prodigy clone. Excellent work transistors J112. I spent testing. Ready 3 boards Moog Prodigy DIY. Just work exellent 2N5457, is a good choice.

Excellent! I hope so too :) I advise you to download the latest addition. About connections CV / GATE and adjustments. :school:

For all! Documentation for adjustments Moog Prodigy clone DIY. This is useful for absolutely everyone who builds a Moog Prodigy DIY. :school: The corrected file, connect CV / GATE / S-TRIG... :selfhammer: Good luck! EnsureSound

Transistors 3906 rotate correctly? I use the same CD4007UBE and everything works fine! I never had a problem with ADSR in Moog Prodigy DIY. Somewhere you have an error without an oscilloscope will be difficult to find. Make high-quality picture of your PCB, by the ADSR. What would have been...

Many thanks LED-man! It will be useful to all. :supi:

And of course, any test starts with PSU. :school: And check all the voltages on the chips +12V/-12V.

Nothing needs to be connected to the S-TRIG. Use only the GATE and CV. You need to check each unit ( VCO1, VCO2, VCF. ADSD1, ADSR2, LFO) individually. Place your order in the chaos, shorten the length of the wires. So it will be easier to deal with problems. Check again that all components are...

Congratulations! :P Waiting for your samples! :phat:

CV - YELLOW, GATE - GREEN, GND - BLACK

Congratulations! :supi: Advanced a step further! Surely there are still bugs to be found. :agent: I have everything working perfectly! Check the assembly, maybe somewhere something's not right. I advise you to check the circuit responsible for the CV and GATE.

Thank you Nordcore for the sensible remark! :nihao: Perfectly! :supi: Then the legs can be soldered exactly! No twisting them ... It is enough to deploy it to 180 degrees, regarding the drawing screen printing. Example for soldering 2N5457 and J112! Corrected by Nordcore:

example of soldering JFET's 2N5457 or J112

3904 and 3906 are soldered correctly! So check also JFETs. Use an oscilloscope to check. Waveform file name correspond to the element, on which should be the wave form.

I do not see clearly the entire board entirely. Although your transistors 3906 are correct! And check the correct mounting legs of JFET J112.

judging by the pictures, I can already see the error ... Pay attention to how you have soldered all 3906, because I did beforehand showed that they should be rotated 180 degrees. After you deploy them at 180 degrees, I hope all the problems go away. Again! Closely familiarize with the...

Attention all those who build Moog Prodigy clone! :school: For proper and stable operation of the VCO1 pulse wave. Resistor R41 must be 18,2K. Resistor R48 must be 38K.

For all! New corrected BOM for MIDI-CV convertor: Not soldering resistor R19! For correct work CNY-17-3... :selfhammer: Regards EnsureSound :nihao:

Both jumpers J1 and J2 must be closed.

Attention to all who build Moog Prodigy PCB unpopulated! :school: Note the pinout (GATE, DRAIN, SOURCE) of the N-JFET transistors (Q13, Q16, Q14, Q20). Depending on what types of transistors you use E112, J112, 2N5457 or 2N4391. What would be correct to solder them to the PCB. Use the...
