Hi, I have a question about portmidi: how to decide buffer size for Pm_OpenInput(). Most of the sysex messages are short, less than 50 bytes. But SysEx is also used to transfer large chunks of memory, such as sending synth patches and firmware updates. And in these cases, very large buffer sizes are required.
Should I define the buffer size for the maximum expected sysex message? Is there a dynamic buffer allocation facility implemented in the library so that each time the current SysEx packet is about to fill up the buffer, a new one, larger, is allocated, and the old one copied into it? Thank you Cecilio Salmeron
