Hey guys,
which footcontroller can control Tap Tempo via MIDI ?

Pretty much all of them, you can do tap tempo via midi cc on one of the instant access buttons. The MarkL pedals have a special function for this on 2 possible buttons.

Thanks,
I read the manuals of the footcontroller you guys have suggested me.
If I understood correctly, you set the TapTempo via midi CC.

I thought there was a more pricise way to do it. Polling a midi message to retrieve a tempo may lead error measurement of about 3-4ms.

Thanks for all the infos.

Doesn't that depend on the polling frequency?

You could also consider an event/interrupt-based midi-in routine...?

Sure. Higher polling frequency, less process can be handled.
Anyway if users are happy with this MIDI CC=>TEMPO method is fine for me

Interrupt based midi -in routine is in my opinion a must.

For 120 bpm (1 beat is 500ms), the error margin (3-4ms) is less than 1%. Seems acceptable to me.

Hi guys,
how does a ground foot controller get the information regarding the effects status (ON/OFF) since it is connected mono directional (only one midi cable) ?

I have studied the manuals of the most common MIDI ground controller and they appear to be quite convoluted and time consuming.

-somewhat related-

The Roland FC-300 has a Patch-mode that allows you to send multiple midi messages for 'select' and 'unselect' of that specific program number. In this mode you could send out a PC to select the patch in the unit and send additional CC's to enable/disable effects in that program.

It also has a sys-ex mode that exchanges rich program information but that requires 2 way connections - either midi or CAT.

I though this info might give you some 'inspiration' ;-)
