New MidiALF firmware version 0.93a is available here.

Change log:

v0.93a
– allow note length longer than the sequence step length (thanks to shiftr @ MI forum)
– rotate sequence commands now rotate linked (16 and 32 step) sequences as a whole
– fixed problem with nonlinear progression sequence re-staring from where it was stopped
instead of the first step. Thanks to Jacob Karlstrom.

v0.93
– implemented note CV tuning, see command page/Tune
– implemented CV/Gate output support, compile with ENABLE_CV_OUTPUT define to enable it (see midialf/makefile)
– improved LFO UI: shape set to “none” stops LFO on both CC and CV, CC set to 0 prevents LFO on CC only

v0.92a
– rotating step encoder in step hold mode selects active step

v0.92
– added step hold mode toggled by SEL+CLK
– implemented received CC ignore/receive setting
– implemented root note setting learn mode
– implemented CC1/CC2 number learn mode
– implemented LFO1/2 CC number learn mode

MidiALF/CV prototype pcb’s are back from fab. Built the first prototype — everything seems to work as expected! Hope to be ordering production pcbs really soon now.

A first batch of Jack-o-mix boards is received and tested. Ordering details are here.

I was testing the fab’s ability to handle plated slots and ended with what looks like a pretty useful tool to convert 1.4″ connections to 3.5mm and back. Instead of maintaining a bunch of mixed jack conversion cables I can now just run standard ones through this tool.

Here’s the second revision of MidiALF/CV board, streamlined and improved.

Schematics: alf_cv#1 alf_cv#2

Edit: Gate3/4 connectors were moved to the top of the PCB. The plan is to use taller stand offs on the back side so that these connectors fit in with the MIDI I/O connectors.
