<div> I'm having a strange issue with a custom external built using C++. When using my external in Pd I send it "set" commands using a message box to change internal parameters, e.g [set tempo $1( </div><div>
The strange behavior is as follows:</div><div> 1) Sometimes when opening the patch the word "tempo" as referenced above gets changed to some nonsensical characters or is missing altogether. So my message looks like [set ðLﾸ $1( or [set $1(, even though it was saved as [set tempo $1(.</div>
<div> 2) When the behavior above does not occur (e.g #1) and the message is preserved upon opening, it only will work as written once then the second time the message is nonsense again but does not actually display as having changed. So the GUI still reads [set tempo $1( but actually prints to the Pd window as: print: set ðLﾸ 140. </div>
<div> 3) At times when running my object, after #2 has happened, Pd crashes and leaves a trace to:</div><div><br></div><div>Exception Type: EXC_BAD_ACCESS (SIGSEGV)</div><div>Exception Codes: KERN_INVALID_ADDRESS at 0x00000000100b1a6a</div>
