I would like to know if, when the channel is muted (as shown in the image below), there is still any processing happening in the instrument on that channel. Does it still use the processor and produce sound that is just muted, or is it not processed at all?
It is only the audio mixer that muted so it’s processing is slightly reduced but the processing of the chain continues.
Thank you for your attention. I’ll use a MIDI signal blocking plugin to make sure there won’t be any processing then. Thank you very much.
is possible to make one button of my controller mute more than one chain? i can’t map to more than one chain. When I make a new map, the old one is canceled…
There are two modes of MIDI binding:
- Chain - this will bind the MIDI CC to the processor parameter only when the chain is selected. This ignores MIDI channel.
- Global - this will bind the MIDI CC to the chain all of the time. This uses MIDI CC number and MIDI channel.
Hi All, first time user and recent Zynthian user too.
I dig into the forum a lot to find a similar situation to mine: I want to toggle mute/unmute various chains simultaneously with a same footswitch.
Zynthian Hardware:
Using a custom one: RPi5, HifiBerry DAC+ Light, MIDI Breakout board connected to RP5 GPIO, USB mouse, HDMI out to a Generic Display.
MIDI Signal Flow:
MIDI Guitar connected to 13-Pin MIDI IN of a MIDI Guitar Converter Yamaha G50.
Sustain Pedal connected to Sustain/Hold input of the Guitar Converter.
Behringer FCB1010 MIDI OUT connected to the 5-pin MIDI IN of the MIDI Guitar Converter.
5-pin MIDI OUT of the Guitar Converter connected to MIDI IN of the Breakout board.
The Guitar Converter is setup in Multitimbral Mode (it sends Strings signals to MIDI Channels 1 thru 6, and Sustain signal on Channel 7).
Zynthian UI:
I have 7 chains created. Some are receiving data from ALL Channels. Some are receiving data from specific channels (e.g.: one Bass chain for Guitar String 5, other Bass Chain for Guitar String 6). I have MIDI-FX Filters in place for the Channels according to the chain.
I can hear sound perfectly from all instruments and even sustain is working properly (the sustain pedal activates layer 7 for solos).
Question:
Please, how do I map a single footswitch on Zynthian UI to mute/unmute Chains 1, 5 and 6, at the same time?
The footswitch (pedal 1 of the FCB1010) is sendind CC#20 on channels 1 thru 7 (guess it does this because of the Multitimbral setup of the Guitar Converter).
I have tried various filters / configurations, with no success.
Also have tried MIDI MAP rules, with no success (only the last rule is accepted, when trying to remap the same combo of Channel/CC# to different Channels/CC#s).
I have also tried MIDI-learn, but the behavior is that it only assigns a same Channel/CC# to a single Chain, it does not accepts multiple Chains reacting to the same Channel/CC#.
Edit: I have also tried Global MIDI-learn, but once I click on it, the screen blinks and instead of going to a similar MIDI-learn screen with the green question marks, it goes back to the Zynthian main UI screen.
Thank you very much in advance for your help. And thank you very much for Zynthian.
Hi @numa! A very warm welcome to the forum. You want to MIDI learn to the mute of several chains. Unfortunately, Oram does not support learning the same MIDI CC to mutliple controls in the mixer. Vangelis does support this so you have a choice, implement a convoluted solution (that might be possible), update to vangelis (with the risk or running the unstable version) or wait for this feature to land in the next stable version (which could be some time off - at least several weeks, if not months).
Thank you very much for your reply, @riban!
I will test Vangelis to see what I could achieve, while I await the update Oram in the future. Where can I find Vangelis to download? I have foud the Zynbleton Vangelis READ ME page here in the forum, but I could not find a link to download it. I have also looked at the Zynthian Wiki and internet in general.
Edit: I have found how to change and update the branch to Vangelis. I am going to test it and will report. Thank you!
You don’t need to find it you already have it.
The different threads of development, Oram , Vangelis and others yet to come are nothing more than branches in the github repository where the zynthian code base lives.
And because this is managed with git on the zynthian itself you are not downloading a whole new chunk of software you are merely selecting it from what you already have on board.
And this is done in the zynthian webconf on the software page under the version section.
All the normal warnings about backing up your work before attempting this change apply, as you are moving to an environment that doesn’t claim backward compatibility.
There will of course be the customary social charge we apply to all our readers. . .
Thank you very much, @wyleu !
