Guest zomoipotoi Posted July 9, 2003 Report Share Posted July 9, 2003 How many controls (CC) I can vary at the same time using a MidiBox-Plus or MidiBox64 or SID without an error message?I've seen error message like "MIDI overload" (or something like that) when i changed very fast the program change of my SID (PIC 16F877 mounted).Now I'm building a new extension based on Flex sensors (http://www.imagesco.com/catalog/flex/FlexSensors.html), something like the Power glove, which must have a lot of contemporary control changes (11 in my plan) and i want to be shure that the midibox support so many events at the same time before continuing the project.Sorry for the bad english!Thanks Quote Link to comment Share on other sites More sharing options...
TK. Posted July 9, 2003 Report Share Posted July 9, 2003 Hi Zomoipotoi,I cannot give you an adequate number as this overrun issue depends on a lot of parameters (SID sound engine load, used CC, sent notes). It happens due to a too small MIDI buffer in the PIC16F based firmware which affects the realtime capability, there isn't enough RAM free for a larger buffer.My suggestion: when the MIDIbox SID should receive a lot of external CC data, switch to PIC18F - I never noticed a buffer overrun in this implementation.Best Regards, Thorsten.

Guest zomoipotoi Posted July 9, 2003 Report Share Posted July 9, 2003 Thanks, I'll use the PIC18F of course for all the next controller/SID.Bye!!! Quote Link to comment Share on other sites More sharing options...
