We tested HerMIDI 2 weeks ago with Werdy's Waldorf Bloefeld, and it worked perfectly, so it's added to the surely compatible devices' list...

(Anyway, I have parts for 10 HerMIDIs to assemble at hand, so if someone can't build it for himself/herself, I can build and send one... )

HerMIDI is now proven to work with CASIO CT-640 synthesizer. However, this keyboard relies on 'running status' very much, it sends MIDI status-bytes only when it's really necessary, and sends only note+velocity bytepairs for a long period. This means that you need to do a little preparation to ensure the notes are caught by receiver.prg or SID-Wizard. Either:
-Turn the CASIO on AFTER enabling HerMIDI in SID-Wizard.
-Press any control on the keyboard (e.g. instrument-select) to cause a proper full note-on message which will ensure proper processing of the upcoming notes.

(This can be the case for some other keyboards, and this is probably true for other MIDI-cartridges, not just HerMIDI.)

Such a nice add-on to SID-Wizard, now it works great with my keyboards! :)

This is an improvement/fixing update for HerMIDI 1.0. Now it's more compatible with many MIDI-keyboards and synthesizers due to the implementation of the 'running status' feature which was missing until now on C64-side code (HerMIDI-C64.asm).
No change to the hardware at all, the PIC hex-file and the PCB is all the same fortunately.
Read README.txt for more details. The well working tested devices so far:
-AKAI MPK25 MIDI-controller
-Elka MK88 master keyboard
-KORG 707 synthesizer's DIN MIDI-output
-Korg MS2000R
-Miditech "midistart music" USB MIDI-keyboard
-Roland XP-30
-Swissonic CK490 USB midi-keyboard's DIN MIDI-output
-Yamaha PSS-790 Keyboard
-Yamaha AN1X Keyboard
-Yamaha RM1X
-Yamaha DX7IID

miscellaneous (computer/controller/etc. outputs):
-Arduino serial port (used for MIDI)
-Sonar X2 with M-Audio Delta 1010

Models that didn't seem to work:
-Roland D-50
