automs70

Automate up to nine knobs of the MS-70 CDR multieffect.

automs70

This script allows to automate up to nine parameters of the ZOOM MS-70 CDR multieffect. For each knob you can set the minimum and maximum value. The value will change using linear interpolation between randomly chosen values in the selected range, with a BPM related speed.

Requirements

norns
MS-70 CDR

Documentation

Connect the MS-70 CDR to the norns and set it as the midi first device.
Use the encoder 1 to select one of the nine controllers.
The encoder 2 sets the minimum value and encoder 3 sets the maximum value that will be sent to the MS-70 CDR.
Pressing key 2 you can select the effect and knob destination.
Use key 3 to randomize min/max values.
Automs70 can be also used to generate nine MIDI control change commands: define in the norns parameters menu the destination CC number and relative midi channel.

Installation

In maiden’s repl, enter:
;install https://github.com/pangrus/automs70

Changelog

V1.1

Excellent news - I have an MS-70CDR clamped permanently to the outputs of my Norns Shield, and this will be just the ticket!

Does this work with the MS-50G as well? Just connect usb and go? Ty

No, you have to change the script. Search 0x61, replace it with 0x58 and it should work. Let me know, I don’t have a MS-50G to test.

don’t have the Zoom but this is great for using as a base for other midi pedal scripts. great stuff, thanks!

Hey! Excited for this script! I tried this with my MS-50G and just updated Norns shield.

I changed the two instances of 0x61 in lines 23 and 24 of automs70.lua to 0x58, saved the file and slept for good measure. This is what Matron says on launch:

# script load: /home/we/dust/code/automs70/automs70.lua
# cleanup
# script clear
# script run
>> reading PMAP /home/we/dust/data/automs70/automs70.pmap
m.read: /home/we/dust/data/automs70/automs70.pmap not read.

___ polls ___
amp_in_l

cpu_peak
pitch_in_l
pitch_in_r
# script init
>>

…but, the pedal doesn’t seem to be responding. I am pretty new to all this, so maybe I am missing something basic. Any ideas? Thanks!

Hi, you must change also line 196, and it should work. Let me know!

landsort · January 5, 2021, 5:41pm

Thanks for the quick reply; can confirm that after the line 196 change also that the little knobs on the MS-50 are moving and all is working great now!

Many thanks for the Automs70.

UPDATE: After a time running the script, the interface on the Norns shield freezes up and becomes non-responsive.

A ;restart from the Matron repl stops the script, but if I relaunch Automs70, the interface is frozen again immediately. A sleep restores everything to working as expected, but after a few minutes (maybe 10?) we freeze again.

pangrus · January 5, 2021, 8:02pm

Weird…when freezed, what happens if you disconnect the USB cable?

landsort · January 5, 2021, 8:24pm

I disconnected the USB cable, but that didn’t appear to do anything different. The interface on the Norns shield is still locked up, but this time I also lost the network connection so I can’t talk to Matron. I really like the script, though! Right up my (ambient) alley.

pangrus · January 5, 2021, 10:03pm

I’ll try to reproduce the crash in the next days. Thanks for reporting it, I’m glad you like the script.

EDIT: @landsort I just updated automs70! Now you have the parameter “MS type” and you can use it to select the MS-50G as destination (no more lua editing needed). I’ve also reduced the parameters update speed to avoid device crashes. Please, let me know if it works on your multistomp.

landsort · January 7, 2021, 7:41pm

Hi Again!

Sorry for the delay, my Norns and I were apart for awhile. Yes, I was able to select the MS-50G in the edit menu and everything is working as expected. Haven’t seen a crash after more than 30 minutes running.

EDIT/UPDATE: @pangrus Still purring like a kitten after having run all night long!

pangrus · January 8, 2021, 8:10pm

Many thanks to @landsort for the testing.
Cheers!

cliffemu · February 6, 2021, 5:16pm

Thanks for making this. Testing on MS50G here. Looks like E4 and E5 knobs aren’t turning. E1, E2 and E3 are fine.

pangrus · February 7, 2021, 2:38pm

You are right, same on the MS-70CDR. This depends on the Zoom firmware. I’m going to reduce the effect range to 3.
