I’m trying to take this on port by port on the midihub side of things to start. All my controllers (LF+ 12+, Moog MP-201, and SA reflex expression pedal) have their outputs merged by a MIDI solutions Quadra Merge, then a single MIDI out goes to IN A on the midihub. Out A on the midihub goes to a MIDI solutions Quadra Thru, which then goes out to feed the midi inputs of the 3 aforementioned controllers, + an RJM mini effect gizmo X loop switcher for program changes and loop order sysex.

here to ask the pros, what filtering would you apply between in A and out A, given this configuration? i feel i have a general idea, but could use insights as i’m new to midihub and midi in general.

We can get to Ports B, C, and D later

Hi @jazzboxuz welcome to Midihub.

So you’re essentially focussing on
{FAMC|MP-201|Reflex} → {QM} → Midihub → {QT} → {FAMC|MP-201|Reflex|Gizmo}

Given that MH A → A unfiltered will send everything {FAMC|MP-201|Reflex} → {FAMC|MP-201|Reflex|Gizmo} …

…It seems to me that it boils down to

• what messages of those sent from each of the 3 sources to do you want to affect (one or more) of the 4 destinations?
  (ie. what do you want each the 12 pairings A → A to do?)

• which messages might need filtering to say avoid loops?

• which might you want to filter just because they’re superfluous and you want to reduce the ‘chaff’?

• which might need modifying (eg. channel remap) to be recognised by a given destination?

As a starter, I’m picturing something like this as an example of the extra info needed:

(This simplified setup is from part 5 of this tutorial series, btw)

away now, but I’ll take a 2nd look tomorrow in case I can help

[jazzboxuz]

thanks I’ll check out the tutorials and go from there. I was trying to start off by getting midi clock distributed from the midihub back to all my controllers, as well as to other devices connected to Out B, C, D.

Is there a way to set up tap tempo to control the midihub clock BPM? I had it mapped to a momentary midi CC button and it would alternate between 30bpm and 200 something bpm, so i guess a min and max value. is there some other type of message i can map to have it work as a tap tempo?

tutorials
the tutorials are aimed at giving a hands on experience assuming no MIDI knowledge.
You will likely find the one on the MIDI monitor (SbS04?) useful as it shows how to make it a central tool in checking that your message flow is doing want you want

clock
If that’s all that you need to send out to FAMC|MP-201|Reflex|Gizmo then looks like you don’t need any A → A pipelines.
What you’ve just described would look a bit like this:

featuring:

• Clock filtered out from A-IN (just in case any of FAMC|MP-201|Reflex pass it on!)

• use of a Virtual I/O to send Clock to all outs (Virtual ports are a v. powerful MH feature)

• label for Virtual C changed to aid readability

• Virtual A-IN left trailing as a “To Be Continued…”
  You’re likely to have at least one of these for each MIDI-OUT that you want FAMC|MP-201|Reflex to control. Each will probably have channel filters and the like

tap tempo
There is currently no Tap Tempo pipe or Tap Tempo property for Clock.
It’s come up perhaps surprisingly infrequently as a request.

The key entry in this short list is @Giedrius here, saying

Tap Tempo is simply not implemented yet. How it could work is to provide a parameter that could be mapped (like “Manual Retrigger” in LFOs) that would react to taps and adjust the tempo.

Now, a number of long-time users are watching for the latest firmware update that it appears Giedrius is currently working on because it might include what promises be a revolution in mapping.
But apart(!) from that, G hasn’t given any indication of other new features

my guess, @jazzboxuz, is that the user base for Midihub when it started was skewed toward synthesists. Now, as the audience gets broader as Midihub’s reputation spreads, perhaps there’ll be more demand for functionality like tap tempo. Maybe Giedrius will include it in FW 1.14.x!
