20.01.2021 Firmware #5.631, EEPROM #5.631, Editor #5.630, FPGA #10012021

• Firmware: Distortion on H100 percussion notes fixed
• Firmware: Bugfix for organs configured with tab switches, will init start-up correctly
• EEPROM: Reduced busbar levels (standard value 100 instead of 127)
• EEPROM: Reduced Vibrato/Chorus dry/wet levels to prevent distortion
• Editor/Updater: Increased reliability, will shut down drawbar, pot and button scanning during update
• Editor/Updater: Trackbars will not send new value until mouse button is released; prevents crashes on particular PCs
• FPGA: Better 6550 tube simulation, results in somewhat softer overdrive
• FPGA: Higher Tube Amp Gain, lower AO28 Preamp noise

24.11.2020 Firmware #5.622, Editor #5.622, FPGA #29112020

• Changed rotor diffusor/filter/mixing coefficients in FPGA
• Reduced noise in AO28 amp simulation
• Fixed small bug in Editor (crash on Load INI file)

26.10.2020 Firmware #5.621, Editor #5.621

• Firmware: Added feature "MIDI CC Threshold" for tabs and inverted tabs to switch on or off by specific controller value
• Editor: Added drop-down menu items "Threshold" and "Threshold inverted"
• New CC set "#0 NI B4 D4B", can be uploaded alternatively to "#0 NI B4 d3c" (CSV file, use MIDI CC Editor)

08.10.2020 Firmware #5.620, FPGA #01102020, Scan #5x.29

• Firmware: Bugfix, Hammond SK CCs did not respond to drawbars
• Scan Driver: Bugfix, bug in all scan drivers prevented reception of MIDI sustain and sostenuto commands due to NI B4 CC set anomalies
• FPGA: Bugfix, wrong phase relationship of DAC MCLK signal caused audible artefacts on Extension Board audio output
• FPGA: Changed AO28 simulation noise behaviour to "somewhat better than new B3"
• FPGA: New swell pedal filter arrangement for better S/N performance
• CCSET: Deleted unnecessary entries for Hammond XK/SK MIDI (CC #66 prevented sustain pedal function)

Note: AO28 simulation adds some "coloured" noise to input and intermediate tube stages. S/N ratio is in the -78 dB range, so noise is somewhat lower than on a real B3, although noticeable. This is intended.

31.08.2020 Firmware #5.619, FPGA #310082020, Editor #5.618, Scan #5x.28

• Firmware: Bugfix, H100 Percussion distortion when multiple harmonics activated; level reduced
• Editor: Added separate Save/Open menus for INI files
• Editor: Added pop-up menu (right mouse button) for main table
• FPGA: Added highpass filter for vibrato LC line reflection
• Scan Driver: Bugfix, PERC ON on NI B4 CC Set did not work, route-through for Sustain and Sostenuto CCs implemented
• Updater script: New params for vibrato
• Finalize scripts: Enable drawbar save on #1498

Note: Check for System Inits parameter #1498 bit 7 (leftmost) is set, otherwise drawbars will not be saved. Default value for #1498 is 135.
