Re: Panels from Lower West Side Studio

I'm not sure about the Oakley logo. Tony if you're around could you please provide some insight. The one in the middle here? http://www.oakleysound.com/index1.jpg I don't actually use it myself on my own panel designs. But it is used on the Krisp1 built Oakley modules, so it's probably best not to ...

Re: Behringer/Klark Teknik 3rd Dimension BBD-320

Warning: Total nerdy post. So I have had a bit of time to look into the circuitry of the BBD-320. Of course, being surface mount I've not been able to trace out the whole schematic but I've looked at some of what I think are the important bits. The circuit as expected is very similar to the Roland....

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

Just to make sure im not missing out, all the ics face the same direction on the main board right? Yes. All ICs are all aligned the same. Can you check that both RN3 and RN4 on the main board are the correct way around. Pin 1 should be in the square pad which is towards the top of the board. If all...

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

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. This is possibly a problem with the LOAD_A and LOAD_B signals from the main board. Measure the voltage at pin 13 of U3 on the main board. ...

Re: Behringer/Klark Teknik 3rd Dimension BBD-320

Mine just arrived from Thomann. I've already taken it apart and had a bit of a look inside. The BBDs are V3207 running from 8V. From a quick inspection the circuit topology looks like the original, but I need to dig deeper before I can say for sure. There's way too much exposed mains voltage around ...

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

All ground pins are connected. 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. Also measure the voltage on the 0VA test pin with respect to the PSU's 0V output. This...

Both parts should be the same. The R at the end indicates that the devices has been delivered to the supplier on a large reel.

Gate out works on both channels at a voltage of +5v if gate is and +12v if the switch is off? Gate off should be 0V and gate on should be +5V.

[Build] Oakley Croglin filter for Eurorack

The Oakley Croglin, originally a 5U module, is now also available as a Eurorack module. The 10HP wide Oakley Croglin Voltage Controlled Filter (VCF) is based around two low noise 'Sallen-Key' filter circuits that operate either together or against each other. http://www.oakleysound.com/Croglin_e_1.j...

http://www.oakleysound.com/Croglin_e_1.jpg The Croglin is now available for the Eurorack system. It's actually not quite the same circuit as the 5U version as I couldn't get a dual gang 1K pot in the smaller format that I needed. So this meant I had to completely redesign the cores of the filter. R...

Re: What is the worst synth sounding you ever bought and why ?

For me, it has to be the D-110. Sounded like the ROM-samples had died inside the unit and their zombified remains then came out moaning and wheezing whenever you fed them MIDI. No amount of layering or FX could breathe life back into those stiffs. The D-110 was the backbone of my musical output fro...

Re: midiDAC question

... so you just generate a fast attack long decay/release envelope to make a gate? You'll have to play with the settings as it will depend on the sample used. I think fast attack and no sustain, but a bit of decay and release. The sample you use should be really short with a fast attack and decay -...

Re: Behringer Roland System 100M clone

OK, I have had another look and I think there is a NC lug and it is connected to the signal lug on the top side of the circuit board. This means to free the NC lug you'd have to remove the socket, cut the trace and solder the socket back. Not easily done as the socket's ground lugs are soldered to p...

the Blofeld has repeatedly crashed on me. I'd swap it right away. I think mine has only frozen once in all the years I have had one. Mind you, I never use it in multi mode.

I get 0.348 when release is maximum and -0.119V when release is minimum.
Right, that bit is working. Given those values it is quite possible that the 2180 is not working correctly.

One more thing before you buy another THAT chip, what's the voltage across R37 as you vary the release control? That is, red lead on one end of R37 and black lead on the other end.
