*
* X32PunchControl - a windows app for managing DAW punch IN/OUT down mixing updates
*
* Change log
* 0.01: Creation
* 0.02: Added button & bank capability - code cleanup
* 0.03: Midi out & Midi in OK - enabled MTC to display
* 0.04: Midi selection through dropboxes - fixed reset functions behavior
* 0.05: Better logic around file handling
* 0.06: MTC now functional for play/punch - code cleaning
* 0.07: Get Frame rate from MTC to recalculate more accurate time
* 0.08: Use 8 buttons.
* 0.09: Use a different .ini import mechanism / Enable merging off only faders
* 0.10: fixed bug in the Bank selection; added a Record imply Play selection option
* 0.11: got rid of "reset temp file"; added a default select for MTC vs. LTC
* 0.12: forgot Xrecord flag in XExecuteReadMerge(); changed text Midi: ON/OFF & MERGE: ON/OFF
* 0.13: code cleanup; better handling of catchback when REW button/GUI is used
* 0.14: code cleanup; handling of catchup when FF button/GUI is used
* 0.15: missing exit-loop condition in XCatchBackProc()
* 0.16: new algorithm in catch-up XCatchBackProc()
* 0.17: Better handling of early stop, ensuring work will not be lost
