• Audible key off noise when Contact Damping param > 7

02/07/2018 Firmware 4.25 for XB-2 mk3/mk4, FPGA #25042017

• Updated firmware in folder Flash_XB2_mk3 to latest version
• Problems with secondary MIDI input: Newer FPGAs seem to have stronger internal pull-up resistors, so second MIDI input (often used for bass pedals or drawbar controller) may not work properly. Please update to FPGA #25042017 if you experience this issue. Do not use FPGA #25042017 on older mk2 boards (#24042017 is OK).
• Small changes to HX3 Remote to fit small screens (notebook etc.), "moved folder" bugfix (resets file info when path to parameter files does no longer exist)

11/05/2017 ScanCore #24 for SR44, SR49 and SR61

• "Last note on lower manual distorted" bug fixed for ScanStrip16 and ScanInline61 boards
• Silent Update for Expander/Drawbar Expander mk3/4 Firmware (no new version number):
• Will accept MIDI CCs for swell and volume on all 3 channels now

04/17/2017 Firmware #4.25, FPGA #17042017

• ARGHH! Rotary Sim volume permanently set to 0. Bug fixed. No new version number.
• Slightly changed FPGA 17042017 to match TG Flutter setting of previous versions
• DO NOT USE ZIPs from 04/14/2017!

04/14/2017 Firmware #4.25, FPGA #10042017

• Glitches in filter assignment and leakage generation fixed
• internal signal processing with more headroom
• Tuning capability, parameter "TG Gears Tune" on display, A = 433 to 447 Hz
• phase and amplitude noise/leakage improved
• Sustain/sostenuto hardware inputs on MIDI and FatarScan Core, see below
• Sostenuto CC #64 works also on FatarScan if enabled by MIDI CC (*.) menu
• Lowered distortion on TG notes 48 and up, less interference
• Hardware inputs on PL16 for Sostenuto/Sustain pedal connection
• Sostenuto working with MIDI #64 and hardware inputs
• Improved key velocity on MIDI out for FATAR (also available as separate ScanCore update)
• Improved click evaluation in MIDI and FATAR scan cores
• Lowered rounding noise of vibrato scanner, was noticeable with no drawbars pulled and key pressed

Completely revised my old generator design, dating from 2012. There might have been a glitch in my old code that assigned wrong LC filter numbers (i.e. their simulation) to some generator notes, so some notes were to weak or too loud even with "new" tapering. New generator has a smooth response with "new caps" selected in menu. Please revise your own tapering files if needed. Also FM/phase noise revised, may need readjustment of TG Flutter param to get that "blowing a bottle whoosh" (can't describe it better) on each note.

Otherwise empty PL16 on mainboard was only used to output an auxiliary MIDI signal for Neo Ventilator speed control on pin 7 and some internal test signals. It now uses separate input pins 4 (for lower manual) and 6 (upper) for sustain and 3 (lower) and 5 (upper) for sostenuto, working with FATAR and MIDI scan cores. Switch pins to ground (pin 10) to activate sustain or sostenuto on particular manual. An additional 10-pin header is needed, solder in PL16 position. If you don't need separate sutain/sostenuto inputs for upper and lower manuals, just connect both inputs for each function, i.e. 4 and 6 for sustain and 3 and 5 for sostenuto. Do not bridge all 4 inputs.

NOTE: Hardware input pins only work with FPGA #03042017 and up.

Both are controllable by MIDI CC #64 also (wired by "MIDI CC set" menu to either sustain or sostenuto). These functions work even on splitted manuals, so if you have lower on left part of manual, pin 3 affects only sostenuto on left side. I think this should fit all needs.

03/17/2017 Fatar ScanCore #32

• DO NOT USE PRELIMINARY #31 or #32 from 03/15/2017!

  • If set to ON, organ will close key contacts on 1st FATAR rubber contact and send MIDI ON immediately, but without velocity.
  • If set to OFF ("George Fleury" mode), organ will close key contacts on 2nd FATAR rubber contact and send MIDI ON with velocity.
• New menu "TG Gears Tune" and HX3 Remote Parameter 488, TG Tuning will fine tune the organ plusminus 100 cent. Note: To accomplish this, all TG gears must be changed which may take around 100 ms.

07/24/2015 Firmware #3.822, HX3 Remote #3.82

• Fixed a bug in HX3 Remote, lost licences when updating firmware
• HX3 Flash minor changes for reliability

07/09/2015 Firmware #3.822, FPGA #05072015, ScanCores #17

From firmware 3.82 and up, HX3 will not send own MIDI CCs on MIDI OUT when MIDI Option = 3 (RcvSndMgNoCC). MIDI Option = 3 is now default on all firmwares except HX3 Expander (which has to accept MIDI CCs). This change has been made since the MIDI CCs HX3 sends out may disturb connected MIDI workstations/arrangers. Note: If send/receive of MIDI CCs is enabled (Option = 1 or 2), HX3 will transmit its own CCs (drawbars etc.) always according to NI B4 set, independent from selected MIDI CC interpreter.

Independent from MIDI option selected, HX3 will always send a 3.3V TTL level MIDI signal on PL16 pin 8 for controlling Ventilator/Minivent DSP board with synced stop/slow/fast. Pin 34 of Vent DSP board is MIDI TTL input. Also wire digital ground (PL16 pin 10). Ventilator DSP accepts MIDI CC #21 values 0 (stop), 1 (slow), 2 (fast) on channel 1.

• RcvSndMgNoCC option is now default on HX3 firmwares except for HX3 Expander
• Added MIDI CCs for Hamichord/Mojo CC set:

• 1 = Rotary Slow/Stop/Fast (modulation wheel),

• 91 = TG Leakage (is "Crosstalk" knob on Mojo),

• 92 = TG Cap set (is "Keyclick Length" knob on Mojo),

• 95 = Swell Trim Cap (is "Percussion Volume" knob on Mojo)

• Additional TTL MIDI output for controlling Ventilator/Minivent DSP board (see above)

06/29/2015 Firmware #3.812, FPGA #29062015

• New HX3 Remote with improved MIDI CC assignment. In conjunction with firmware 3.55, it will display and select received MIDI CCs for easier assignment of custom MIDI CC sets.
• MIDI Route-Thru to HX3 Remote. Small bug fixed in Voce MIDI CC setup, added controllers 87 (Treble Equ/Tone) and 88 (Bass Equ).

06/04/2014

• Reverb amount may be adjusted for each of three tab settings separately
• Bass and Treble tone controls have wider range
