This does not happen at all if I am using Kyma solely to process external sounds, as I have been doing mostly of late.

But when I generate sounds from Kyma, it is rather dramatic.

I am getting a rather horrible constant clicking, which (curiously) is not recorded if I record the audio. I know this because if I play the audio file through my main audio interface outside of kyma, the clicking has not been recorded. However (which seems to follow) if I play the audio file from within kyma, the clicking is there, but apparently because it is being generated anew....

I will have to monitor this further. It does not always happen - I had 2 timeline tracks using the samplecloud sound, with lots of modulation, running without incident last night.

well, I do generally use outputs 1&2....but the problem is just very sporadic. I can't find what triggers it, or at least I haven't yet.

I do plan on updating the interface in the next few months, so I suppose that I can live with it until then.

(the problem occurred again last night. This time there were no 'internal' sounds - the sounds were all coming from outside with a little processing on one track. Rebooting everything fixed it. Previously it hadn't been so easy)

What sample rate do you run the MOTU at? Also how many I/Os are enable?

You mention that you split your soundcards between two different Firewire controllers so what follows is probably not the cause of the problem but worth mentioning, especially if you are running the Paca(rana) and MOTU at 96 kHz.

FireWire bandwidth gets used up pretty easily with a "large I/O count" soundcard on the same Firewire controller. This can be especially problematic with multiple soundcard on the same bus (which is why this is probably not your problem).

Plus if even one of the audio streams has to run at FW400 speed it forces all of the audio traffic to happen at FW400 speed. This can even impede the FW800 traffic between the computer and Paca(rana). So heavy streaming from Kyma to the Paca(ana), like when processing samples or playing disk-based samples, plus all the audio I/O, can end up saturating a FW bus if the audio sample rate is 96 kHZ. One thing to keep in mind is that even idle soundcard channels consume FW bandwidth. If a channel is unused use the soundcard's control panel to disable the unneeded channels.

* make sure you are using a power adapter rather than bus power on the 828

* perform a Factory Reset using the 828's front panel Setup button

* try a slightly different I/O Delay (either the next smaller or next larger value) under the lower left drop down menu (Configure) in the DSP Status window in Kyma
