A few years ago I found a binary at the Leeds FTP site, compiled for the operating system (SGI) I was using at the time. It was called het_export, and the utility performing the reverse operation was het_import. I still have the SGI binaries, but no SGI. I'd like to find the source code for these - some programs I wrote at the time, to edit .adsyn data before resynthesis, need that format to work and it will be a huge drag to rewrite everything... problem is, I can't find binaries or source code for het_import and het_export at any of the FTP sites.

What are the subscribe / unsubscribe details? Currently the Csound Front Page: http://mitpress.mit.edu/e-books/csound/frontpage.html has details for the old list. I think it is a good idea to have a footer on each item the list mails out listing how to unsubscribe and where archives and further information can be found. Also, I think it is a good idea to have a distinctive prefix on all mailing lists, such as: [CSND] It needs to be brief, and best in upper-case and square brackets. This assists people like me who see all their emails, including those from twenty or thirty lists, in their email client's In box. I use Netscape and have extensive filtering to move incoming list messages into their mailboxs. It is highly convenient to see all incoming messages still in the In box even though they have been sorted and moved to their various list boxes. (They are flagged that this has been done, and compacting the folder takes them out of the In box.) Seeing something like [CSND] or similar helps me browse the emails, and is especially valuable if there is a non-descript subject line from someone I don't recognise as being a Csound list member. - Robin =============================================================== Robin Whittle rw@firstpr.com.au http://www.firstpr.com.au Heidelberg Heights, Melbourne, Australia First Principles Research and expression: Consulting and technical writing.

Subject: Re: [Csnd] Win NT Problems take 2 I am responsible for coding winsound, with considerable help from a number of people more knowledgeable that I am about Windows (Richard Dobson for one). I run on Windows95 (two versions) although I have recently acquired Windows98 on my Linux number 2 machine; I have not tried Csound on that machine yet. I do not have access to NT anywhere I know so am dependent on what I am told. If you can tell me more clearly what does not work I would happily look again at the code, or anyone else who wants to can. ==John ffitch -- To unsubscribe, send email to csound-unsubscribe@lists.bath.ac.uk Mailing-List: contact csound-help@lists.bath.ac.uk; run by ezmlm Precedence: bulk Message-ID: <381C3F4A.FC84DE0C@cableinet.co.uk> Date: Sun, 31 Oct 1999 13:08:26 +0000 From: Richard Dobson Organization: Composers Desktop Project MIME-Version: 1.0 To: csound@maths.ex.ac.uk References: Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Subject: Re: [Csnd] het_import/export If you can get through to the Bath server, the sources for both het_impo and het_expo are included in the source distribution, spread betweeen the main source directory and the 'exports' folder.
