A.J. & George-I see nothing mentioned in the last two SD-1 revisions-that clearly point out changes to the Vocalizer. In other words,A.J.- is this a patch you 'worked up' and gave to George and Dan for distribution as requested by SD-1 owners? If someone finds the patch, could you please forward a copy my way with install instructions.

A.J. -With reference to written material for the Rev 2 and 3 builds-I know its available on the net under 'New features of upgrade xx.xx' - but this should only be temporary information. Surely Ketron will produce proper modified pages -where necessary(on the net)to replace the out of date pages in the owners manual. Its hard enough for a new SD-1 owner to figure things out-without going to add- on reference pages for the latest software revision information.
