Can you please explain your whole setup? Include all the pieces, if you can. Thanks
Midi Designer , is used as control panel for Sample Tank (= sound module app )
When i disable Midi designer  and play directly on Sampletank via MIDI
( wit an organ , hardware connected with Roland Midi cable to Ipad )  - -> no latency
When Midi Designer is started up and controlling Sampletank  , and i do the same      --> latency of ca 0.3 sec

Very annoying when you play piano, guitar , harp etc.
How is the midi cable connected to the iPad? Thanks
Why not route the keyboard to sampletank and not process it through MIDI Designer Pro?
Connection Midi cable Roland UM-ONE MIDI interface mk2-->  Apple camera connection cable -->  IPAD
Why not route the keyboard to sampletank and not process it through MIDI Designer Pro?
Because the instrument/combi  selection is too complex in Sampletank and the potmeters are to small to use it for live playing.
That's why i choosed Midi designer , to have a usable control panel, only.....the latency ...is gigantic.

I like MidiDP but it cannot be the intention of a MIDI control panel, to introduce a huge MIDI delay, no  ?
Hi Roland,

Thanks so much for your messages and the dialog. We're very much looking forward to getting you sorted.

Thanks so much for pointing out that latency when playing piano keys would be a huge problem for you and render MD unusable. Let me assure you that not only are we committed to solving this problem for your specific case, but we are also musicians and have thousands of users working on MD with no particular latency. Your use case is very particular, since you're playing a HARDWARE keyboard through MD and then passing that information on to SampleTank. This is NOT THE CORRECT SETUP, though we in the future of MD this setup might be contemplated. FOR THE TIME BEING what you need to do is to use MD to control Sampletank but to AVOID USING MD AS A TRANSLATION APP. To do this, simply shut off the UM-ONE as an input for MD. So the UM-ONE should be going to SampleTank and MIDI Designer should ALSO be going to Sample Tank, but the hardware keyboard should NOT be processed through MIDI Designer.

Of course, if any of this proves to be difficult, we will work with you to find a setup that is acceptable, and if we have to modify MIDI Designer to make your use case work, of course we can, and FAST. But for right now, let's try to focus on removing this annoying situation by solving the problem using the tools we have at hand. Later we can discuss other ways that MD could make this situation easier for you.

Thanks for the patience as we resolve this problem WITH YOUR HELP.

Best!
Dan

User says, "OK , i will try that .

Indeed there is no need to send note information true MD
If i can stop that , with this solution, i think the problem will be solved.

Question :
If i stop the UM one as input , can i make that permanent,
or do i need to do every time again ?

MD has only to do the instrument or multi selection,  and that's all.

I keep you updated."
Yes, MD should remember the connections that are unchecked. Let us know if you find that this is not the case, thanks!
Yeah !!!   Problem solved !

All midi inputs off. Note information , straight to Sampletank.
Output , Sampletank , that's all .

I also use Midi Bridge ( for midi filtering , and velocity curve correction, )
but that's situated between the Roland UM ONE cable and Sampletank.
Also switched off in MD. outputs

Thanks a lot for the support !



Best Regards

Thanks Roland, glad you're happy. Don't forget to leave a NICE review in the App Store if you feel like it, but most importantly: enjoy!
