[Sugar-devel] Fw: Sugar on a Stick - and OLPCsound

[Art Hunkins]

Hi (a newbee here) -

Below is a mail sent to the Csound developers listserv, seemingly about a 
difference between build 802 on the OLPC, and SoaS. The difference leaves 
those of us working with Victor Lazzarini's csndsugui (a git project and 
Python utility for Csounders) dead in the water.

Has any developer here an idea of the problem and what it will take to solve 
it? Specifically, are there any differences between SoaS and the current 
Sugar implementation on the OLPC that could be responsible?

Thanks for any insight.

Art Hunkins
