  1. Thank you a lot for your advice! It is great that the ports are compatible! I found the infos in the wiki: http://wiki.midibox.org/doku.php?do=search&id=midiphy Even thought the new schematics are not online (or I did not find them), the descriptions of the changes are pretty helpful.
  2. I've got the same thing happening, when I attach the GM5 I can adress the first 4 ports, not the 5th. Looking at: https://github.com/midibox/mios32/blob/master/apps/sequencers/midibox_seq_v4/core/seq_midi_port.c The enumeration goes until "USB4" at several places, the enumeration of the USB ports looks like a static definition. There is no "MIOS32_USB_MIDI_NUM" like for IIC it's MIOS32_IIC_MIDI_NUM. I guess it could be hacked to get more USB ports, but then also the flags-words (for mute seq_midi_port_multi_enable_flags etc.) will need to be adjusted and so on, like for the IIC ports
  3. I want to extend my Midibox SEQ V4 with CORE_STM32F4 and V4+ firmware that is based on wilba CS frontpanel with midiphy PCBs. But I did not find schematics to check the connector pin signals, if they are compatible. From first sight it looks like it may be possible. Specifically I want to use: RES-SD PCB to add a SD-card socket (this one is not super important) MIDI8 PCB instead of using the longer-size 2xMIDI_IO I2C PCB for 4 MIDI extra outs (I guess multiple of these boards could be used for more midi outs as described here: http://www.ucapps.de/mbhp_iic_midi.html ?)
