(use a symbolic "noteon" message instead of it's encoded uint32_t equivalent¹) - - use Pd native types where this is not possible but still feasible (e.g. if your "channel number" is encoded as 32bit uint, you will get away with a 23bit integer - as is provided by Pd's t_float type) in virtually all cases) - - where it's absolutely necessary to be able to feed your objects with a 32uint_t from within a Pd-patch, you could always use list of two numbers (just read them as two shorts and recreate the uint32_t from that). just make sure that you don't end up with multiple pairs in a single (user-exposed) message) fgmasdr IOhannes PS: congratulations to the MMA committee for chossing a clever, unique and unambiguous name like "HD". ¹ please note that i have absolutely no clue about the internals of MIDI-HD; so the "noteon" example might not be the best one; but i hope you get my point. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBCAAGBQJU6uj1AAoJELZQGcR/ejb46g0P/2S2ilG2CSGUG3qieqdlElzM V3geR92nrk2J96ahu03SW1Z4FM7Gfh+Xvff3Gpez8+Dv7EeoDD4bGlLSHNQ96Ig+ gJws2TOGILKhtC/s25J7C5OxPHIG6C7H9+wIwlRljaa8UqvXpDDRLGmPIuE8BxTK sCo/HlBYXBLEu9fjuam9M3SlTAxjIMYPKGuoNUUeUkZx3pRX2n7hd0+WPak4BOlI WMtuJrqYH7ReYtgxupQsvwwvuXN9CzYVmeFDaYimQabBY+areU6S/BXWLrSB4Hfb KhTYO2nPatvgE5smfovgvSqb2fQTIlUDvriV4zXDWaP+tpoAULagcAcLNDiMPxaC jbpRRjYI+q4sxyb59mLYxtXMJsVkJOy/BvPjVo/6J2I0yjiZSqHa1zohysA5/5Lu rYUogSg4cAryrw4LS30b44COt1IxgxK574IVYGqpDC04zItQu3OnwduPsuuUmZKi mNbmKWnXuk2fpGDGeLc3SyFbgIKzA7fadQcG3yM7A6+gFbdZM+npfQNRtZwdRoNv QiJHehIpBlUr/I1X2cdHS6IVGRs7COkzblAR4MFhEQs7zmZ9IYZfoFfOmpGpUgMx kYQCDHBGaZGKR9wQWe1NE9XRDJMuJwO1/QVTeSc2UlWdj4Ei/VFG4/gVt268mvg4 K9dE7uHFNBEc/ACcmKKo =dN9m -----END PGP SIGNATURE----- _______________________________________________ Pd-dev mailing list [email protected] http://lists.puredata.info/listinfo/pd-dev
