and thanks for your reply. I am glad that a higher level of control is

You are correct about MIDI... outdated stuff. Espc with the sample

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.

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
