Multiclock - delay to start on bar for Midi Clock

Kurtsch · December 14, 2021, 9:32pm

Hi,
This functionality would allow the unit to function similar to the ERM-Multi clock.

Adding a bar length to the master clock or adding a “slave clock” that has a beta count and will only start at the start/end of the beat clock loop after being triggered. Can be downstream of a clock source use of midi cc/note to start stop the slave clock.

I have a rudimentary sketch on an arduino that may be useful, would also be happy to help code if you guys are open to that sort of stuff - feel free to email me.
P.s. love the midi hub!!!

That is exactly the thing I try to build - would free my MIDIPAL for other purposes

This can be done using Sync Delay pipe - it drops Clock messages until its counter reaches 0, this way you can make the clock to be delay-started by a whole bar (for example, use the value 96 if your time signature is 4/4 - one quarter note is 24 MIDI clocks)

yes, but you can´t trigger this behaviour synced so that it can give a start on beat.

hehe ok

it is actualy possible to do that even without SYNC DELAY but,
i also agree that it would be amazing to have it backed into CLOCK pipe ,it would be pipes saving and elegant

so

what you need is two CLOCK with START and STOP controlled via same midi buttons,
first CLOCK is master clock to drive LFO
from there on you can add as many CLOCK as you want
and extra midi buttons to control BEAT DURATION parameter,

i am sending all remote buttons to
USB A
ch13 cc120 -MANUAL STOP cc121-MANUAL START
ch13 cc20 off 54 on 78 BEAT DURATION 4-8
ch13 cc21 off 0 on 43 BEAT DURATION 1-2

now
all CLOCK need to have same mapping for STOP & START

all added CLOCK pipes after first CLOCK need START to be additional mapped to LFO output

buttons for BEAT DURATION need to be set also into CC REMAP pipe to remap and used also as STOP for (CLOCKS execpt first one)

LFO is to send START message every desired by you interval ,it needs to be also additionaly mapped to all CLOCK STARTS execpt first

first row CC REMAP is to convert same as BEAT DURATION buttons for STOP for CLOCKS,
because pipe can only convert 2 CC’s you need to add same whole pipe line if more than 2 buttons added

it goes like this

1.press START - all clocks are starting (you can have multiple output with each individual BEAT DURATION settings)
2.when button for BEAT DURATION e.g. 8 mapping is pressed its also STOPS desired clock(but not first one)
3,now same CLOCK just awaits START message from LFO which outputs START every deisred synced interval
4.winner-winner chicken dinner!

i have raspberry pi pico with 10k pot and this code to act as simple one pot midi controller for BPM in midihub

pi pico as simple midi controller
pi pico python bundle
thonny ide for pico

but of course any midi pot will do

tested with two octatracks.

ask me if you need help.
