sms pd external - design choices
by Rich E 25 Aug '08

25 Aug '08

Hi all, As I may have mentioned in a few other places, I have been working with a c library for analysis/synthesis known as SMS. The library, although in flux still, is now capable for performing synthesis in real-time; I wrote a prototype external that does this by reading a streaming file from disk. Now, I want to turn write a set of externals using a buffered analysis. Originally, I thought that all operations to the buffer would happen using one external, but this now seems like it will get too messy once anything more than basic operations are attempted (something like cross-synthesis would take enough code to constitude its own external). So, I have decided that, like the process of SMS, the different modes of operation should be seperated into analysis, synthesis, and editing. However, they would all still need access to the same buffer (which could also be its own external, or possibly be inside the analysis external). So now I am looking for a way to make it where various externals have access to the same buffer - a data structure containing a header and sequential frames of analysis. I originally thought that outputting a pointer would be the easiest, but then realized that pd can output 'gpointers', which are not the same as a void pointer. So it does not look possible to pass a regular c pointer around in pd land. I see that [pool] has the ability to share a data space among different buffers by taking a name as its first argument. I am digging through its code right now, but am not familiar with the flext API. I don't yet see how it manages to allow different [pool]'s to share the same data. Any suggestions from this list is appreciated.. cheers, rich On Jan 27, 2008 6:01 PM, <geiger(a)xdv.org> wrote: > Quoting Rich E <reakinator(a)gmail.com>: > > > Hi Gunter Geiger, pd devs, > > > > I have recently begun to write an external for SMS synthesis, by basically > > porting the command line tool Xavier Serra wrote within the original SMS > > code (found at http://www.iua.upf.es/~sms/software/Old-SMS-for-NextStep.zip). > > I was talking to Xavier about this and he mentioned that you almost got an > > external working with sms..
