CP3 Mixer module PCBs are available for purchase. This is a faithful recreation of classic CP3 Mixer in MOTM format with “signal present” and “clipping” LED indicators. See details here.

A new variant of popular MidiThru MIDI splitter is available: it’s two MidiThru’s in one case. More details here.

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

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.

You can download Midi2CV Mk2, MidiARP and MidiSEQ source code using the following links:

MidiARP: midiarp_095a_src
MidiSEQ: midiseq_097a_src

The code can be built using WinAVR-20100110 toolchain available here: https://sourceforge.net/projects/winavr/files/WinAVR/20100110/

Have fun hacking!

Here are a few variants of acrylic MidiGAL cases, the clear green glass ones are usually in stock and are sold for $30 with all the required hardware: 4 x 10 and 22mm stand offs, 8 x top and bottom panel screws (hex head), 4 x side screws with nuts, switch knob, encoder knob and plastic bottom sticker pads.

MidiSeq firmware has been updated to v0.97: MidiSeq_097. This update adds Program Change handling options: now the sequences can be changed externally using Program Change events. Also added ability to disable sequence transposition.

Long overdue MidiSeq MIDI step sequencer demo video is now available:
