midi cc not working on preenfm3?

[sisyphus]

trying to control midi cc on preenfm3 with cirklon. For example CC# 41 / 42 aren't affecting anything. is there a secret handshake to enable this?

Hi,
What do you expect from CC# 41 and 42 ?
They don't do anything.

Midi CC are the same as for the preenfm2.

Hello,
i think it's about reverb param, as written here :
https://github.com/Ixox/preenfm3/blob/master/firmware/Src/midi/MidiDecoder.h#L67

yes, the midi cc handling for those params is missing.
I can prepare a PR for this, if needed.

I saw i deleted this part in an "integration" commit some time ago.
I think that was because there are math processing that must be done in FXBus.paramChanged() when a param is changed.
And the midi direct change does not call this function.

Not sure we want to allow continuous midi CC that triggers paramChanged() on every change.

ok, you're right, it would be quite cpu hungry to deal with it like that, so i added some slowndown in the CC handling mecanism :
It would now recalculate changes once in 100 blocks.
Reverb params should not be realtime handled by CC anyway, it may be usefull to change once when loading songs or scene changing.

Another possibility is to drop off completly midi CC for reverb params and let people manage various reverb configuration with mixer files instead.
Which seems to be a good enough solution as you can easily tweak all parameters on the preenfm.

@sisyphus, what do you think about this ?

Doh! ahaha yea, I was looking at the LSB row for some reason.  Nice work! & thanks for the quik reply. works like a charm (:
