In Step-by-Step.03, we used filters in MIDI Monitor
to better understand the data coming in from two devices.
In this activity, we will use Midihub to control the data going out to a synthesizer, sampler, or another sound module
We’re going to use the sequencer and KeyStep37 MIDI controller like before.
Follow along in your own way with your gear
Let’s start!
Cables needed: USB & 2 MIDI cables.
Other gear: Two MIDI input devices & Midihub Editor like before
(optional): a 3rd cable connected from MIDI OUT-A to your sound module
Let’s return to the patch for the “2 to 1 MIDI MERGE BOX”:
Connect all your devices like last time and switch them on
Connect to Midihub Editor and…
…Open the ‘Merger2to1.mhp’ patch you saved at the end of Step-by-Step.03.
In Step-by-Step.03, we checked the data…
… from each OUT-A port separately
but it’s useful to check them together so:
First do File
→ Save As
and rename the patch ‘Merger2to1VirtualA.mhp’ or similar
Now we’re going to change the patch…
…by adding virtual pipes…
…to make connections ‘inside the box’…
… like this:
Now change the patch to make these new connections…
try it yourself …then check below…
Now Save
the changes you’ve made to ‘Merger2to1VirtualA.mhp’
Let’s get testing!
We’re still using a Sequencer on MIDI-A…
…and a MIDI controller keyboard (with an arpeggiator) on MIDI-B
First we check the filters in MIDI Monitor
:
We don’t want to see Clock
or Active Sensing
Next we check the data coming in to MIDI-A:
it’s as expected…
Then we check the data coming in to MIDI-B
with the Arp ON:
as expected, BUT SEE the BPM is 30!…
…that BPM needs to be 96 to follow the tempo of the sequencer on MIDI-A
…
…so let’s fix that on the KeyStep on MIDI-B
:
(more on syncing tempos later )
Later we’ll pick up one more thing wrong on the KeyStep
NOW we’re ready to check the merged output
To make a full check:
We’ll select Virtual-A-IN and
- Start the Arp on MIDI-B
- Start & Stop the Sequencer on MIDI-A:
Just LOOK at THAT BPM!
Are the two MIDI Clock
sources messing with eachother?
Let’s Check…
…Stop the Arp on the device coming into MIDI-B…
…and check again:
…it certainly looks like that!
We will fix that problem of two Clock inputs in the next section…
