nuke Posted September 21, 2011 Report Share Posted September 21, 2011 hey...since i started to build a new custom version of the seqV4 board, i wonder if there´s a physical connection to MidiOut 4? i can change the midiport to MidiOut1-4, IIC1-4 etc. but MidiOut4 is signed with an asterix...is this just a dummy or placeholder?...or is there a "real" port somewhere on the board?...MidiOut1-3 are already connected and working... sm:)e, nik Quote Link to comment Share on other sites More sharing options...
TK. Posted September 21, 2011 Report Share Posted September 21, 2011 OUT4 and IN4 were placeholders. Since you are not the first one who asks for this, I finally enhanced the UART driver for OUT4 and IN4. It will be available for MBHP_CORE_LPC17 at J4B (which is intended as second IIC port, but can be alternatively used as fourth MIDI port) MIDI Out is available at J4B.SD, MIDI IN at J4B.SC The fourth MIDI IO isn't supported by MBHP_CORE_STM32 The pull-up resistors can be removed, but this isn't necessary: If you are using an optocoupler circuit, and already soldered R10/R9: add another 2.2k in parallel to R10, this results into 1.1k which is ok Best Regards, Thorsten.
