Major update to MIDI2CV Mk2
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
LFO specifications:
- 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
EG specifications:
- 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.

MidiSeq demo video
Long overdue MidiSeq MIDI step sequencer demo video is now available:
New MidiGAL firmware: MidiSeq
MidiSeq is a polyphonic MIDI step sequencer with some great features, such as note step advance, step modifiers (tie, half, strum, and accent), super stable internal clock, nice swing and two modulation sources with velocity, after touch and CC destinations. More details here.
New MidiGAL firmware: MidiArp
MidiArp is an advanced MIDI arpeggiator with a few twists, check the details here.
New project MidiGAL
MidiGAL is a simple Atmega328p based MIDI controller board featuring 8×2 LCD, MIDI IN/OUT connectors with LEDs, one encoder and one switch. It can run a bunch of different firmware variants (updatable via Sysex), including original unmodified MIDIpal firmware.
One cool firmware available for MidiGAL is MidiClk — high precision Midi Clock Tester/Generator that is capable of straightening up your DAW or iOS MIDI Clock. See more details here.
