Have you looked at midish? The latest commits to the GitHub mirror of its development repository are dated three weeks ago and it comes with a comprehensive manual.

hey not sure if im too late! its just midi date luckily. check out the midimuso site. all you need is (if you have it a usb controller keyboard with a midi out???) send the files available at the bottom of this page through midi drag it into logic or something and press play http://midimuso.co.uk/index.php/cv-12/
alternatively! you can send a program message on program change I think 100 and then send the corresponding program after. you can actually do this with a beat step pro if savvy enough!
just read the manual on the midimuso site it will explain 
no sysex

Yeah, realised this morning it was not sysex ( my first experience of Midi back in February was trying to reload the default patches to a Korg M1. They are not forgiving and the cheap USB midi cables are no use either )
I have cakwalk on the DAW ( have to hope it still powers up as not had space to set it up since lockdown ) which will hopefully do the job.

I had missed the section in the manual.
I think a little PCB and Duino to send Midi CC will be in order… have to put my thinking cap back on… I have actually done some previous Midi CC stuff for controlling QLCPlus Ligting

So I have a music video shoot today and the midimuso has stopped sending cv and gate. Midi indicator still lights up but nothing happening otherwise. We start shooting again @ 5pm but will only have a limited time before that to troubleshoot since they dont let the band on location until 4pm. (Covid propocal) Kosmo is on sight and has to stay in place so yeah, crunch time! Any help would be amazing, thank you in advance, crazy day…

cv and gate on all of the channels? even channel 1? sheesh! close. if its still coming out of channel 1 its getting signal

1 and 2 nothing, going to check the rest when I get there. Everything was 100% for day 1 and 2 pre pro but audio session last night it wasn’t working.

aaah typical, seriously sods law ever time. things break when you need em. I know the feeling lol.
im really not sure where to suggest where to start. if the signal is flashing on the midi it means its working up to the atmega chip. wether the atmega chip is working or not is hard to tell from the front.
is the daisy chain connector bit definitely popped on?
is the clock of 6 flashing?
hmmm

hmmm dont remember if the clock was flashing. Ill have to see whats up with the connectors when I get there.

Well didn’t fix it but still got to track some noises. Sampled some loops just using LFOs and twisted them with the Boss 505C. Not exactly what I wanted to do for it’s maiden voyage but still captured some cool sounds.

Glad you managed to save the session.
Did it stop working after being shaken in transport (ICs or connectors shaken loose? Marginal solder joint cracked from moving shock or thermal shock?)
Or did it stop working after you sent some MIDI through it that might have changed the mode of operation? (Side effect of sysex sent do another synth on the same MIDI chain? Just brainstorming / grasping at straws here.)
Let us know what you find.

Yeah I think the issue was that they moved it after we left on Saturday. They sent stills of the lighting setup and my Kosmo was moved from my side of the stage to right next to the drummer. They said it looked better for the shot. Well that doesn’t work for me at all if it’s 10 feet away from me just because it looks better. So I told them it had to be moved back so I could play it or I was taking it out of the shoot all together. So they moved it and when I fired up my rig it didn’t work. At that point it was useless to get pissed so I just tried to fix it with what little time I had, to no avail. So I just hooked up the LFOs and cranked the delay and started making loops and sampling them into the 505. Then I just played those loops for intro and transitions between songs. Shot 4 songs, playing them like a live set to capture the feel. It’s all to raise money for Midwest Music Foundations Covid relief project.

Been reading the .sch on the blog and getting confused by the component designations and the setup of the TL074s. U7E, U8E and U9E all have two 100nF decoupling caps close to ground, same with U12C, but U11E stops abruptly. I’m assuming there should be 2x 100nF caps going to ground for them as well? Asking here, as I think it makes the number on the BOM not add up, since there’s no C26 and only 10x 100nF caps (when you’d need 12 to cover U11).
Am I getting myself confused, or is there an error in the .sch?
Thanks!

Just posted by Rob Cottam:
For those who have a Midimuso CV-12 device.
There is now an online tool for easy CV-12 mode changes.
Tested working in Chrome and Microsoft Edge.
Should work in Opera, Android Webview and Samsung Internet browsers.
The CC slider doesn’t work on touch screens - fixing that tomorrow.
Please make sure no other MIDI software is running (DAWs such as Ableton, Cubase etc.) as this app won’t be able to see the available MIDI interfaces if they are already in use.

There does indeed seems to be something a bit strange going on in that part of the schematic.
That little stub of wire off pin 4 of U13E for example.
So either the decoupling capacitors got inadvertently cut, or not pasted, or Sam decided that there was enough capacitors already.
Standard design practices would put two capacitors there, but since U11 is only driving gate signals, noise is not a big issue here.
What is a bit scarier is that there is no decoupling capacitor anywhere near the microprocessor on the board.

Hadn’t even noticed that until you pointed it out! I wonder if adding a cap between AREF and GND would help calibration in the long run, or just better signal reliability. I’ll probably pop one in just for good luck. Thanks Antoine!!
Normally
You probably don’t want to couple the noise from the digital VCC to the AREF input like that.
You should DEcouple the AREF with a capacitor to ground.
but
In this case, as the microcontroller’s ADCs are not used, AREF really doesn’t matter, it’s just VCC that should be decoupled.

Wow! I was using an old android phone MIDI player. This is so much better. Thank-you!
