Re: miRack (iOS) Expert Sleepers modules

Os, If using mirack or vcv for the matter, if is send 1 volt into mirack trough an es8, and then send the same voltage out i dont get 1volt out, most of the times its a few milivolts off. I was wondering if there is a way around this since i wanted to use mirack and similar for precise voltage usage...

Re: MX9 9x9 Pin Matrix Module

Hi! Could this be used for precision voltage summing with the buffered version? So i could send a 1volt on one channel and 2volts on another channel, sum both of them into a out and i would get 3v? Im thinking of using it as a sort of precission adder like the dopefer precision adder.
Cheers

Re: Problem with Euro Sequencer Cv out 1 and some other issues.

Hi Tony, Its was the same mistake from the controller board.......resistor networks had pin1 inverted. Manage to desolder both witout causing damage to the board or the resistor network, soldered them back and its all working how its meant too.

So....one more day :(

Changed ic 15 and 3.

No changes.

I have notest that i used NPN 45v BC550CBU, but i also have BC550BB 1G.

Re: Problem with Euro Sequencer Cv out 1 and some other issues.

Hi Tony, Since im running out of options, do you think its makes sense to start replacing parts related to the mentioned ics? I checked all caps and resistor values according to the schematic and they where good. Some where a bit off but i think its due to being soldered to the boards (some resistor...

Re: Problem with Euro Sequencer Cv out 1 and some other issues.

Hi so i made the tests: "Measure the voltage at pin 13 of U3 on the main board. It should be +5V but I think it may be 0V. If so, this is where the problem lies." Its 5v. "With the power off, check the continuity between pin 14 of U3 and the cathode (the line) of the big diode D12. You should get a ...

Re: Problem with Euro Sequencer Cv out 1 and some other issues.

Thanks for the reply and info.

I changed the ics and put the panel back on.

Performed all the calibration steps.

Going to look into the load issue, see if i can fix it :)

Re: Problem with Euro Sequencer Cv out 1 and some other issues.

ok, that fixed it. Now i have cv on both rows :) Still dont know what to do about the need to have all the load switch on leave (middle pos) and first (or any other) step on load on, for the sequencer to work. Its not the behaviour what its described in the manual.... I have the right size ics now, ...

Re: Problem with Euro Sequencer Cv out 1 and some other issues.

Are resistors network RN" and RN3 oriented differently?

One has the silkscreen name on the left (RN2) and the other on the right.

Just realised there is a square indicating pin 1 and its not the same orientation for both Resistor networks :(

Re: Problem with Euro Sequencer Cv out 1 and some other issues.

Ok, Resistors and caps related to CV_OUT_B1 are correct per schemartic. U9 and U20 (tl072) have both pin 5 @ 0V. Tested all ics. Power +12v and -12V and GND on the expected ics and all the logic ics show 0 and 5v where expected too. Im pretty sure by now its not the main board....moving to the contr...

Re: Problem with Euro Sequencer Cv out 1 and some other issues.

Ok more tests... Reflowed power connector. Connected module to my monster case. Gates are the correct voltage. 0-5volts Row 1 fully functional (i think) x1 x2 x4 switch shows +1v +2v and +4vç Row 2. Nothing. The only thing outputting voltage is CV outB2 that goes from 0 to +10volts and gate B out th...

Re: Problem with Euro Sequencer Cv out 1 and some other issues.

Hi tony, Voltage across d12 is 5v. Voltage on pin 14 of u27, its 5v. "It would be wise to check the voltage on any of the sockets' screw threads (or the metal panel if it is fitted). This should be 0V with respect to the 0V output on the power supply."" It is 0v . "Also measure the voltage on the 0V...

Re: Problem with Euro Sequencer Cv out 1 and some other issues.

Last thing before i go to bed, i renember i run out of rl072acd and used 2 tl072acdr instead.
Can that affect performance? Datadheets look very similar

Re: Problem with Euro Sequencer Cv out 1 and some other issues.

Also, another pointer,
ALL switches must be on the the middle "leave position for the sequencer to advance.
If i turn one off, it wont work.
