Hello! It's my first post and first of all thanks for this great site! Also it is my first MIDIBos device... At first i'd like to run the core module...so I burned in PIC 18F452 bootloader_v1_2_pic18f452.hex successful. But when I attempted to start it, my MIOS Studio in midi in monitor showed me following strings: 00000000820453 ms | [D0 78 00] Channel 1: Channel Pressure value: 120 00000000820453 ms | [D0 20 00] Channel 1: Channel Pressure value: 32 00000000820453 ms | [D0 00 00] Channel 1: Channel Pressure value: 0 00000000820454 ms | [D0 01 00] Channel 1: Channel Pressure value: 1 00000000820455 ms | [D0 3F 00] Channel 1: Channel Pressure value: 63 00000000820457 ms | [FF] System Reset 00000000822346 ms | [D0 78 00] Channel 1: Channel Pressure value: 120 00000000822346 ms | [D0 20 00] Channel 1: Channel Pressure value: 32 00000000822346 ms | [D0 00 00] Channel 1: Channel Pressure value: 0 00000000822347 ms | [D0 01 00] Channel 1: Channel Pressure value: 1 00000000822348 ms | [D0 3F 00] Channel 1: Channel Pressure value: 63 00000000822349 ms | [FF] System Reset 00000000824237 ms | [D0 78 00] Channel 1: Channel Pressure value: 120 00000000824237 ms | [D0 20 00] Channel 1: Channel Pressure value: 32 00000000824237 ms | [D0 00 00] Channel 1: Channel Pressure value: 0 00000000824238 ms | [D0 01 00] Channel 1: Channel Pressure value: 1 00000000824239 ms | [D0 3F 00] Channel 1: Channel Pressure value: 63 00000000824240 ms | [FF] System Reset e.t.c. with period 2 sec.
