Known differences between LA32 hardware control rom revisions: (MT-32 is based on thread at quest forums)

Model	Control ROM Version	Notes
MT-32	1.04	unknown, initial release?
MT-32	1.05	Volume knob changes are now interpolated as opposed to directly applied to the data, allowing for much smoother volume changes when using the knob
MT-32	1.06	Rhythm selection Bender Control is now reset when MIDI All parameter reset is recieved, and when MT-32 Active Sensing is not received. Displays will not change, even when a Display Change exclusive MIDI message is recognized, unless the current mode is Master Volume input mode (e.g. Power-up default)
MT-32	1.07	Fixes a bug related to specific values in uninitialized sram on startup causing the unit to act bizarre.
MT-32	2.04	Unknown (possibly the first 2.x mt-32 rom. contains changes boosting the level of the la32 chip to de-necessitate the 14-bit hardware dac-hack, and changes related to the demo mode expanded rom, and the changed hookup of the volume knob, and possibly other changes related to the MT-32 2.x pcb)
MT-32	2.05	Unknown
MT-32	2.06	Unknown
MT-32	2.07	Unknown
D-50	1.04	Initial Release
D-50	1.05	Increased output level.
D-50	1.06	Fixed bug where changing patches changed output modes. Fixed bug where chorus modes 5 and 6 were the same.
D-50	1.07	Reduced noise in chorus sound. Fixed KEYFOLLOW bug where opposite effect as was intended occurs to TVF ENV DEPTH.
D-50	1.10	Includes all additional features from Version 2.10 but works with older upd78312-017 R15179261 CPU/Board
D-50	2.00	Same as 1.07 but add support for new, faster upd78312-022 R15179266 CPU/Board
D-50	2.10	Adds ability for transmitting MIDI Program Change messages, adds Sysex patch dump feature, adds Seperate Portamento and Hold effects for each key when in Dual Key mode
D-110	1.00	Initial release
D-110	1.01	bugfix
D-110	1.02	bugfix
D-110	1.03	bugfix
D-110	1.04-1.05	not released
D-110	1.06	bugfix

• Lpc table type is determined by looking at the 0-encoded coefficients on the K8 and K9 columns, arbitrarily.
• Chirp table is type 1 if entry 37d is 0, and 2 if entry 37d is 1. Other entries also differ, but that one was chosen because of its obviousness.

There seem to be 4 chirp types over the chips:

• The 'patent chirp' used in tms5100/a(tmc0281/d), tmc0280
• The 'CD2801 chirp' used in tmc0280, cd2801 (speak and math, speak and read, language translator, and MAYBE Mitsubishi 'borrowed' it; the chirp is almost exactly the same as the patent chirp, just 25 bits differ and no value is more than 3 away from the patent value)
• The 'CD2802 chirp' used in cd2802 (touch and tell)
• The 'later chirp' used in cd2501e/ecd, tms5110/a, tms5111, tms5200, tms5220/a/c, sum16 of 0x3da

There seem to be 2 energy tables over the chips:

• The 'patent energy table' used in tms5100 non-a only
• The 'later energy table' used in all other chips

There seem to be 5 pitch tables over the chips:

• The 'patent pitch table' used in tms5100/a(tmc0281/d), tmc0280, cd2801
• The 'cd2802 pitch table'
• The 'tms5110/a pitch table'
• The 'tms5200(cd2501e/ecd) pitch table'
• The 'tms5220/c pitch table'

There seem to be 4 LPC tables over the chips (not including pitch and energy):

• The 'patent LPC table' (tms5100/a(tmc0281/d))
• The 'tmc0280/cd2801/tms5200/cd2501e LPC table'
• The 'cd2802 LPC table' (almost the same as above)
• The 'tms5110/a/tms5220/c LPC table'

There seem to be 2 interpolation inhibit behaviors:

• Energy=0 on unvoiced to silence transition causes energy ramp down
• Energy=0 on unvoiced to silence transition causes interpolation inhibit (sudden cutoff)

There seem to be 2 rate control modes (52xx only):

• Rate control is absent/NOP
• Rate control is present

Hence there are a total of 10 combinations thereof:

• 1: TMS5100/TMC0281 (patent pitch, patent energy, patent chirp, patent LPC, patent interp)
• 2: TMS5100A/TMC0281D (patent pitch, later energy, patent? chirp, patent LPC, alternate interp)
• 3: TMC0280 (patent pitch, later energy, ?(patent or 2801?) chirp, 2801A/5200/2501e LPC, patent interp)
• 4: CD2801 (patent pitch, later energy, 2801 chirp, 2801A/5200/2501e LPC, alternate interp)
• 5: CD2802 (2802 pitch, later energy, 2802 chirp, 2802 LPC, alternate interp)
• 6: TMS5110/a (5110 pitch, later energy, later chirp, 5110/5220 LPC, alternate interp)
• 7: TMS5200/CD2501E (2501E pitch, later energy, later chirp, 2801A/5200/2501e LPC, patent interp, no rate control)
• 8: CD2501ECD (2501E pitch, later energy, later chirp, 2801A/5200/2501e LPC, UNKNOWN interp, rate control )
• 9: TMS5220 (5220 pitch, later energy, later chirp, 5110/5220 LPC, patent interp, no rate control)
• 10: TMS5220C (5220 pitch, later energy, later chirp, 5110/5220 LPC, patent interp, rate control)

The tms5111 is likely equivalent to #6 but the interp mode is unknown.
