With a USB-MIDI Device Connected:
Using a USB-MIDI Keyboard –
•
Plug in a USB-MIDI Keyboard and change to Preset 01.
•
Set up the same patch as the first Manta patch (figure 1).
•
Play on the keyboard! It will do standard monophonic handling. 1A is pitch, 1B is gate,
and 1C is velocity. 2A will be a trigger that you can also hook up to something to get a
stronger attack on onsets.
•
Try pitch bend and modwheel. Pitch bend will raise or lower the pitch by up to a whole
step, and the modwheel will come out output 2B.
•
If the keyboard has some other knobs or sliders, try moving them around. If they default
to output on CC# 1-8, then they will come out the remaining MantaMate outputs by
default. Since that’s unlikely to be the case, here is how you do MIDI learn so that you
can output those knobs and sliders:
•
To set up MIDI learn, press the P button to enter Preference 1. Then press the S button
to enter sub-preference of Preference 1. Turn the knobs you want to learn one by one,
and the 7-segment display will count them. When you are done, press the S button to
return to Preference 1, and then press the P button three times to get back to the default
preference (Preset Select, green LED next to the P button goes out and there are no
decimal points on the 7-segment display).
•
Now turn the knobs and you should see CV coming out on the remaining outputs (after
those needed for the monophonic pitch handling).
•
If you want to save the learned MIDI CCs, you can save a preset by pressing S (7-
segment will flash), and then selecting which present number you want to save to. Then
press S again to confirm the save. These presets are a separate bank from the Manta and
No Device presets, so you don’t have to worry about writing them over.
•
Try out 2-voice, 3-voice and 4-voice polyphony on Presets 2-4.
•
Try out plugging in a computer instead of a USB-MIDI keyboard. You can’t have two
USB cables plugged in at once, so you have to disconnect the USB-MIDI keyboard.
There are no drivers necessary, it just responds as though it is receiving messages from a
keyboard and it works the same way. Test it out from your favorite DAW (Abelton Live,
Pro Tools, Reaper, etc.).
•
When a computer is plugged in, you will also get a MIDI Input from the MantaMate to
the computer whenever a clock happens, whether it is from the external CLK IN jack or
from the Internal Clock. It shows up as a MIDI note-on on note number 60.
Arpeggiator with USB-MIDI Keyboard –
•
If you want to arpeggiate instead of using it as a keyboard, you can set the MantaMate
in Arpeggiator Mode. Press and hold the P button, and then press UP while holding
down the P button. This enters Arpeggiator Mode. Connect a clock source to the CLK
IN jack on the MantaMate (or turn on the Internal Clock), and any pitches held down
will arpeggiate. There are several patterns available, including up, down, up/down, order
touched, order touched backwards, order touched forwards/backwards, random walk,
