How many controls I can vary at the same time?

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

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.

Thanks, I’ll use the PIC18F of course for all the next controller/SID.

Bye!!!
