Author | Topic: adinput 1,2 not showing input |
rafe Member |
![]() ![]() ![]() hello i had an unusual occurance, kyma would not see audio input that was being fed to ad inputs 1 and 2. The audio was present when i patched the input directly to adinput 3,4. i rebooted kyma and still the capy would not see the audio signal. I shut down the capy, disconnected the firewire interface and powered up both and then rebooted kyma a second time before the audio appeared on the visual meters and became audible. any suggestions about why. i have been having a few other oddities in my system, but this is the most blatant of problems, so any input would be appreciated! i am using mac G4 867 quicksilver, os 9.22, cubase vst 5.1. thanks rafe IP: Logged |

![]() ![]() ![]() When Kyma is starting up (also when you change Sample rates or initialize the DSP), it tests the audio inputs and attempts to remove any DC offsets that are present. It assumes that there is not a real audio signal present during this interval of time. Thus, if you start Kyma when there is a real audio signal coming into the inputs, it *can* result in Kyma attenuating the input levels. It sounds like this may be what happened here. A strong audio input signal was present during the start up, and Kyma (thinking that this was a DC offset) attenuated it so much that you could no longer hear the audio inputs on those channels. When you restarted Kyma, the audio signal was not present, so it started up without that attenuation. (The other things you did, like restarting the Flame, did not have any affect--It was the restarting of Kyma that fixed the attenuation). The solution is to turn off or attenuate audio that is feeding into Kyma while it is first starting up. IP: Logged |

![]() ![]() ![]() kyma, the computer and all of the software had been booted previously before the session. I had another session active, which i closed, when the problem occurred (thinking I may have inadvertantly left something hanging that was part of the problem) even though that timeline was not using any of the a/d inputs. kyma would not see the mic pre inputs that are normalled to ad inputs 1 and 2 (the pre amps had not been previously powered up). thanks r IP: Logged |
