Re: [Doepfer_a100] A180-9 multicore

2017-12-30 by Jonathan

Hi everyone. After a bit more research I have answered my own question. There are 8 cores in a cat 5 cable, and Dieter has used all of them in the module. That means there is no separate earth connection. I use nylon washers so my A180-9s were not earthed, consequently when I tes

Does that mean they’ve been wired to US or Euro standard? I’m no expert but we recent had a nightmare installing cctv at work and found the reason was the installers wired some com ports with the US standard so a couple of wires are reversed. Neil Sent from my iPhone > On 30 Dec

Yes, definitely a gate. I was just using “trigger” because I’m concerned about the peak of the attack part of the envelope, not the sustain portion. Although, you can see in the waveforms shown in the video that the sustain level also changes. But all information could be helpful

Interesting question, I’ll check it. But that leads to another question: Does the peak output of an envelope depend on the voltage of the trigger? I would think that as long as the trigger is above a certain threshold the envelope will fire in exactly the same way every time. If

1) I'd check the behavior with another trigger source that leaves the MIDI module out of it as Ville suggested. It'll help isolate the problem source. 2) one theory is that with a single note, the voltage actually starts at 0v but with many notes voltage hasn't quite dispersed wh

From the manual: 6. Appendix Module A-185 has two internal jumpers on its circuit board, which are factory-set to send external CV and gate signals to the system bus (see fig. 1). By re-aligning these jumpers, you can convert the A-185 so that it doesn’t take gate and CV signals
