Hi, Basic schematic is from the post # 7, here: https://www.gearslutz.com/board/electronic-music-instruments-and-electronic-music-production/930211-casio-cz-101-cartridge.html But for the Ram chip I used a one RAM chip HY6264 with appropriate pin adjustment. Read a previously post where described so...

hi,
If some of the bars don't light up not for the reason of a bad soldering contact, but a bad led display, rarely seen it, the better way is to replace the all Led number displays due to possible very different brightness of segments of the different displays.

may be power supply is not healthy

Hi,
Some people suggest using a 1N34A as a substitute for the OA95.
A germanium diode 1N34A has lower voltage range - 65 volts, but current parameters are similar for both of them. Your schematic may be used with the 24 to 30 volts maximum, I think.

Hi,
May be I am wrong, but connection from the Minibrute 2 out to the Volca Sample input will do a job.

There are shown the DI-TRI Option Board connector pinout on the schematic on the page 9.
may be it helps to understand?

Hi,
That's right, I think.
Pin out on the polivoks side are signal to 1 or 3 pins , 2 pin is for signal ground. as seen in

Is it safe to feed the input of a DX7 into the “input” of a Polivoks? There is a five pin DIN input on the Polivoks that goes into the filter. I just wanted to ask about this, I don’t won’t to fry anything A five pin Din input for the Polivoks goes into Analog signal mixer, through a pin 10 in the ...

hi, JH project and the JH triple chorus pcb of course, too, still possible to buy here: http://randomsource.net/haible/vintage ps. In the Triple Chorus i Made some mods and used the MN3007 chips instead of the original TDA1022 BBD's, without any changes in values of another components set. With a li...

Hi, You need a some Ribbon controller for connecting from a soft pot or a pressure ribbon, I think. As possible example for it : https://www.gearnews.com/ribbon-controller-stroking-eurorack-synthrotek/ . There are a lot of DiY ribbon controllers schematics on the net, too. From Ian Fritz, from the E...
