What MIDIMON does
- MIDIMON shows every message arriving from USB, the TRS jack and both Bluetooth links, in hex, in words or both.
- Four sources run at once: USB, TRS, BLE-Periphery and BLE-Central, each shown and filtered on its own.
- THRU routes any source to USB, BLE-P and BLE-C, turning the FM-1 into a wireless MIDI bridge.
- Every route carries its own filter by channel and message type, so clock or stray notes stay out.
- The LOG tab switches with ALGO to KEYS, CC, CHANS and CLOCK views of the same stream.
- It holds the last 4096 messages, with pause, scroll back and a clear that asks first.
- SysEx, system common, clock, transport, running status and faults such as stray bytes all appear as they came.
- SAVE keeps your settings in flash, and the chosen Bluetooth device is kept the moment you pick it.
Its modes
- LOG
- Watch the last messages scroll by in hex, in words or both, with timing, pausing and scrolling back.
- KEYS
- See the notes held on each channel on a zoomed keyboard with velocity and poly pressure.
- CC
- Watch pitch bend and channel pressure as graphs and the controllers last moved as bars.
- CHANS
- Check each channel's activity per source and the last message it carried.
- CLOCK
- Read incoming tempo, run state, beat, song position, clock spacing and assembled timecode.
- FILTER
- Hide or show channels on the white keys and message types on the black keys, per source.
- STATS
- Count messages and bytes per source, messages a second, what was lost and sent, plus Bluetooth state.
- THRU
- Route each source to USB, BLE-P and BLE-C, giving every route its own filter.
