LEM218 V3 / 218e V336.82/19/24Download218e-V3_User’s_Guide_v4.8.pdf

V. 36.8 - when MIDI Clock is active, arpeggiation does not trigger on first key pressed, it waits for the next clock.

Version 36 has arpeggiation clock fixes, a pitchbend pitch CV overflow fix, and improved MIDI handling. There is a new a latch function using pads 2&3, expanded the playable range in edit mode (slightly limiting MIDI channels assignment), and other small feature updates including allowing the other 2 pulse outputs and pitchbend to be controlled by MIDI input for a more comprehensive response to it's recorded MIDI output.
200e-USBFirmware Utility1.8.9 1/29/20DownloadUpdated for macOS 12.x and backward compatible to at least 10.12 (Sierra)

Occasionally, we make changes in a module’s firmware to fix software bugs or to add new features. With the Firmware Utility app can load new firmware to the USB Firmware/Utility card, and then transfer the firmware to a 200e module.
Additionally you can change the USB Utility Card to function as a bi-directional MIDI interface for a 200e system. MIDI channels 1-4 will be sent to the internal 200e MIDI busses A-D respectively and MIDI beat clock can also be sent to the bus system, or output by the 252e. The 218e can also be used to output MIDI note and velocity data.

206e/225e Preset Manager32.31/17/16225Sv323_Primo.hex.zip Required to recognize latest set of modules including the 252e and h-series modules. NOTE: Before updating from a version prior to 31.3 backup the 225 to a card to retain preset names. If you have a 251e take it out of Remote Enable before backing up!

210eControl and Signal Router30.5A7/16/24210Ev305A_SSM.hex.zipCV Resolution improvement with 45x oversampling on existing hardware. Snappier UI response. 30.5 reduced code size to fit below preset memory space

218e31.12/29/20218Ev311.zipThree sustain pedal related fixes: 1) The 218e now senses the polarity of the sustain pedal on boot up
2) The keyboard re-triggers notes even if the key pressed is already sustained. 3) Pressure is assigned the last key pressed rather than trying to average the pressure over all the sustaining keys. This is particularly useful way to get full pressure values when arpeggiating multiple keys with the sustain pedal.
218e30.92/9/19218Ev309.zipVersion 30.9 fixes a scanning bug with key 11 on version 30.8
Version 30.8 Changed MIDI channel input from Omni response to Channel 1 response, saves configuration settings, and adds remote enable and software version reporting

256eControl Voltage Processor30.35/7/12256Ev303.hex.zipFix for knob changing multiple values after preset load.
257eControl Voltage Processor30.21/25/18257Ev302.zipBug fix to properly recognize the Module ID switch.
259eComplex Waveform Generator31.211/26/2024259E_312.hex.zipFixed bugs in knob position reading to prevent skewing. Fixed rollover error on knob hysteresis which fixes squishing bug. Reduced startup time before preset was loaded properly, so now there's only the tone of the preset. Added in a little audio blip to help indicate calibration happened
Standalone mode improvement. It now responds to the internal bus in standalone mode (without a preset manager)
- Long press flashes LED, saves the preset; Short press turns remote listening off and on.
Improved pitchbend response over the internal bus

272ePolyphonic Tuner31.010/1/18272Ev310b1.zipWith version 31.0, slots are permanently assigned upon scanning. But the frequency at the time of the preset save (even if not a saved slot) will be restored initially when the preset is called up. (With 30.8, changing stations by hand will remain saved but are not assigned globally.)
