Hi Jack,
Yes, that was my mistake; I've now attached both the patch and the abstraction.
Thanks! Nick

Thank you Federico, I looked at the page and most suggesstions is stuff I already considered. > > Is the HDSP a PCI interface? If so, pay particular attention to the "pci bus latency" part. Well it is a ExpressCard interface in my case, and I wonder if that qualifies as PCI device. The above pages mentions that PCIe devices are not affected by the irq priorities as PCI does. best, Peter ------------------------------ Message: 2 Date: Wed, 16 Apr 2014 10:55:40 +0200 From: Jack <jack@rybn.org <mailto:jack@rybn.org>> Subject: Re: [PD] PD List (GEM VideoSynth) To: Nick Arner <nicholasarner@gmail.com <mailto:nicholasarner@gmail.com>>, pd-list <pd-list@iem.at <mailto:pd-list@iem.at>> Message-ID: <534E458C.6060408@rybn.org <mailto:534E458C.6060408@rybn.org>> Content-Type: text/plain; charset="utf-8" Hello Nick, Don't forget to reply to all. That could be interresting for other people on this list. The document you sent is now a patch (attached). But what can we do with it ? There is only a single object [video_synth] on the canvas. It seems to be an abstraction, right ? You have to send us the patch AND the abstraction. And where are other objects like [gemwin] ? We are talking about Gem, no ? ++ Jack 06 59 23 94 69 Andr?
