Problem

Kyma often loses communication with the Capybara through the course of the day. Often have to restart the DSP.

(I have the same problem, DK, kymaX 6.13)

One thing that I have noticed is that if another firewire device is added or removed during the course of working, the DSP has to be restarted (sometimes a full power cycle, others simply a re-initialization). This is on my powerbook so I am adding a Firewire 800 device and also have that Firewire 800/400 clone thing that goes with the powerbooks.

Solution

1. Inspect the cable connecting the Flame to the Capybara. It should be securely screwed in at both ends and should not contain any sharp kinks or bends in it. You should never substitute a different cable for the cable supplied by Symbolic Sound. If you have any question at all about whether you have the original cable, please send email to Symbolic Sound describing the color, length, and any markings on the cable so we can verify it for you.
2. Listen carefully to each of the analog audio outputs. If one of the D/As is shorted out, it could be acting as a drain on the power supply and cause this behavior.
3. Ensure that your computer, Flame, Capybara, and all other audio devices are connected to the same power outlet (obviously this requires a power strip). If you have them plugged into different outlets, a ground loop could be adding a low frequency variation to your voltage levels and messing up the detection of logic 1 and logic 0.
4. Remove the top of the Capybara and check the slot jumpers. (These are the small cards we call "leapfrogs" that take the place of an expansion card.) These cards should be firmly seated in their slots.
5. After first unplugging the Capybara (we don't want any electrical shocks), locate the cable connecting the power supply to the motherboard. Unplug it. Then plug it back in. If a thin film of oxidation has formed on the metal contacts, it could be decreasing the amount of power the motherboard is able to draw. By unplugging and plugging it back in, you are scraping the contacts clean and making a better electrical connection.

If you continue to have problems, please contact Symbolic Sound by email so we can help you restore reliable operation.
