In 1.7 "mute" doesn't stop MIDI CC output?

I can't understand the effect the main channel mute button has on MIDI CC output. It seems to do something but doesn't entirely stop MIDI CC transmission. Can anyone offer more clarity ?

Also what effect does "poly" and "mono" have on MIDI CC output ?

In recent tests with the Nightverb and 4 channels of MIDI CC I would sometimes seem to overload and lockup the Nightverb by changing presets when running. These were presets that contained 4 channels of CC info. I got the feeling that the sudden surge of new data was too much. So I wonder if a blanket on/off might have the same issue.

Some gear just can't handle rich streams of MIDI CC input, hence some sequencers offer thinning algorithms etc. If I send too much CC data to my Korg Opsix, for example, it can crash or hang. Back in the old days of MIDI, manufacturers understood this kind of thing but MIDI has become a bit of a dark art in the last few decades. Could be the reverb has a fairly small buffer for incoming MIDI data or something like that. It may be worth capturing a dump in MIDI Ox (or similar) that causes this behaviour and sending it to Erica. I suspect a blanket on/off would make no difference since everything arrives one thing at a time with MIDI anyway, it being a serial protocol and all. Good luck!

I've been thinking on this topic and considering ways to reduce ARP's output. Perhaps options to reduce the CC Output rate (currently 50Hz). MIDI devices can usually handle around 300 messages per second, so 4 channels of CC plus the occasional note message shouldn't exceed this. However, there may be other devices, emitting messages, in the loop and as ARP's capabilities continue to increase, I need to consider and handle potential overloads

In this case though, I think the receiving device does need to handle the overload without crashing.

I'll try the same presets with another machine and see how it goes.

After playing with it for a short while, my preference would be that track mute mutes the entire track including CCs. CC sending is a really cool feature but it takes too long to go through check all modulators on all tracks, turning off any that are modulating a CC. You need to be able to quickly mute stuff imho. I think the fear of sudden jumps is unnecessary. Sudden jumps might already be part of your modulation - and it's how CCs work generally, so shouldn't worry too many people. Anyway, it's a great addition thanks for doing it! Will be driving my Minilogue XD crazy the rest of the afternoon! P.S. Could I suggest holding Set and the relevant Mute button toggles between the button muting notes, notes & CCs and maybe even just CCs? If the button is also RGB it could have a colour for each of the mute types. I think muting just CCs will be handy because, sometimes when you have several modulations running, it's hard to know which is doing what. Being able to quickly mute in this way would really help keep track of what's what.

Cheers for the feedback and your preferred solution I will definitely look into a solution.

Mute doesn't stop MIDI CC output, in fact it doesn't stop the track progress, it only suppresses MIDI Note output. ARP is deterministic so as long as the sequencer is running, the sequences keep going too. This approach keeps everything in sync.

If ARP suppressed the CC Output, then kicked the CC message back in when unmuting, there a possibility of a sudden jump in the CC value leading to undesirable sounds. A bit like when you change patch on a digital synth with pots, the Synth control value and the potentiometer position doesn't match until you turn the knob and suddenly the sound changes drastically.

What led you to the question? Is there a scenario where this behaviour is causing issues?

Poly and Mono Voice Modes have no effect on CC output. They simply control concurrent MIDI Notes. I.e. Poly allows notes to be layered.

Makes total sense now.

What led me to the question was that I was trying to "solo" a particular CC modulation. Toggle on/off now seems a lot more useful :)

Thanks
