Hi all, i'm a french user of lsx so sorry for my bad english... :/

I've a problem with lsx.
When i run a show with 3 dac's (1 riya basic and 2 riya lite) the show "lag"
But if i run the show with only 2 dac's the show works well ...

If someone wants to help me ... =)

Regards

Hello, I have done some testing with the RIYA devices and beleive that it is a problem with the manufacturer's RIYA driver .dll When I test multiple mixes of other deivces: Moncha, easylase, OLSD, etc on LSX there is no jerkiness 'jitter' as there is with 3 RIYA devices. I have tested potential workarounds to the issue in the way LSX talks with the RIYA driver but none was perfect. I have uploaded an LSX update with the best solution I found, until the manufacturer is able to update their driver .dll. Thank you for your post.

actually, I'm having a similar problem, but with only ONE Riya DAC. If I play too many shows in succession, then the program starts to lag. Also, one show I was working on that never used to lag before I tried to play it through a set of galvos has suddenly started to lag horribly. It's very jerky, both in the simulator and on the galvos. The only change I made was when I used the galvos for the first time. I don't get it.

If you're getting jerkiness with the RIYA in use, but not otherwise, it's possible that there is an issue with your RIYA interface. If you have the RIYA Lite, it may need to have its USB cable replaced. There are reported issues with some older model RIYA Lite units and their USB cable.

I've two ryia lite and one riya basic. I can change my USB cable ?
I think my first dac is an old version :/

Yes, find a high quality USB cable,
cut the unused end off,
strip the wires,
open the lite clamshell, note the wire connections,
and de-solder the existing cable,
enlarge the strain relief opening if necessary for your new cable,
and then re-solder the new wire on and close the clamshell.

But if you don't feel comfortable with this, ask a capable friend for a hand.

I changed the USB cable. I solder a shielded cable but I do not see any change. I have a performance this weekend. I'll see what happens.

Ok I try it in the day and I tell you if it works
