This update adds MIDI Channel Learn feature which is useful for applications where the on-board DIP switch is not easily accessible. To learn MIDI Channel, you can now hold down the LEARN switch and play a note on the desired MIDI Channel. This channel will be remembered until the device is reset, in which case the default MIDI Channel specified by the DIP switches will be used.
This update fixes problem with incorrect clock output generated after receiving MIDI Stop followed by MIDI Continue event.

MidiCLK firmware update to v0.99 adds ConstClk page which allows you to specify if MIDI Clock events should be sent to MIDI OUT all the time or only between MIDI Start and MIDI Stop events.
Starting with firmware version 2.0, Midi2CV Mk2 has two extra modulation sources: LFO and AHDSR EG which can be assigned to any CV output. These modulation sources are controlled by MIDI CC commands sent from an external MIDI controller connected to MIDI IN.
Firmware update files (.hex and .syx): Midi2CV_Mk2_v200
- frequency: 0.1-100Hz
- shape: triangle, square, ramp up/down, S/H, random PWM, random lines, noise
- free running or reset on note on
- fade in 0 – 10sec
- bipolar or unipolar
- amplitude control
- segments: Attack, Hold, Decay, Sustain, Release
- segment duration: 0-15sec
- segment shape: linear, expo, sine
- legato retrigger: on / off
- MIDI Clock retrigger: 1/32T – 2bars
- auto gate control – 0-15sec (similar to MS-20 EG)
- looping: off, gated, auto
- inverted: on/off
- amplitude control
In looping mode EG can be used as a fancy LFO with the shape composed by four linear, exponential or sinusoidal segments with the duration specified by Attack, Hold, Decay, Sustain and Release controls.
