Hi Maarten,
and thanks for your reply. I am glad that a higher level of control is on the agenda for Tapiir, as I only think it would expand its functionality immensely.
I am xposting to the PD list, where others might have a great interest in this...

This is something that has been on my TODO list for tapiir for a long while... I think MIDI control would be nice, but it's 7-bit data range is a bit of a problem.
You are correct about MIDI... outdated stuff. Espc with the sample precision of the delays which Tapiir has.
Of course it is possible to work around that with multiple controls per value, but for from ideal. What other possibilities does PD offer? Maybe writing to a named pipe (fifo)? I could easily implement the input part in tapiir.
A fifo could be an option, I would have to ask on the PD list what the best way to interact with that would be. By default, PD prints to stderr, if that helps you at all...
However, some solutions in PD and its close friends exist already. I would advise you to look at netsend [native PD object, udp or tcp flavors] and OSC [Open Sound Control: cross-platform, 3rd party protocol for sharing data implemented in CuBase, PD, Max/MSP, Reaktor and others]. I think espcially OSC would be *very* interesting for Tapiir, considering how easy it may become to use Linux sound apps under Mac OS X in the future.
Or maybe it would make more sense to write an PD object that incapsulates tapiir? I do not know however, if it is possible to use a non-PD graphical UI with a PD object.
The way that VST and LADSPA plugins have been implemented in PD [via plugin~ external object] is always without their native GUIs. Named or numbered messages containing the control data are sent to a single inlet of the object, allowing PD users to make whatever kind of interface they like. If you want to go this route, perhaps somebody on the PD list could point you to some good resources on creating externals. One by IOhannes Zmoelnig is here:

Best wishes, D.

I have been enjoying Tapiir quite a bit, and would like to intergrate it into a performance situation alongside PD & Jack. My question is, what are the possibilities for external control of Tapiir? i.e. : can I send it messages [from PD, for example] which could either change parameters, or use a different .mtd file? If so, what kind of method or protocol would work best?
