Proper Use of the Tap Switch
The MIMX provides a TAP switch that you can use to control the speed
of the effects and the rhythm. You might find this somewhat unfamiliar in
the beginning, but soon you'll be able to use it easily and intuitively.
By clicking(tapping) this switch several times(not just twice), you can
specify the desired speed. As you continue clicking, the average interval
will appear in the
5
Display. A good rule of thumb for use is to lightly tap
the switch in tempo for a complete measure of the passage that you are
about to play.
For those interested in the "technicals", a detailed explanation of how
the TAP function detects the average tempo is given below.
A moving average
A method called "moving average" is used to determine the tempo speed
via the TAP switch. For example if you want to set the drum tempo to
120 BPM, it's quite difficult to specify the precise tempo simply by click
the TAP switch only twice.
Four-value moving average (here we will use four values for our explanation)
The average value of the four most recent operations of the TAP switch is used as
the value. This allows any inaccuracies of your actual operation to be absorbed.
Two-value moving average
You will need to press the TAP switch at an accurate rhythm
so that the interval between the first and second presses of
the TAP switch is 60/120 seconds = 0.5 seconds.
The MIMX uses a seven-value moving average. By marking the beats
with the TAP switch, you can obtain a more accurate tempo setting.
About the "currently-edited" indication of the center display
The MIMX has a "currently-edited" LED that will light as shown in the
illustration below.
The MIMX provides analog-type rotary
controls in the interests of operability.
However when you click a channel
switch A1-B5 to recall the stored set-
tings, the sound settings recalled to the
front panel control knobs will not nec-
essarily correspond to the physical
position of the knobs. For this reason,
when you click a channel switch to re-
call a memory, and then move a con-
trol to a position that differs from the
memorized value, the "currently-ed-
ited" LED in the lower right of the
5
Display will light to indicate this. When you move the control to the posi-
tion that corresponds to the memorized value, the "currently-edited" in-
dication will disappear. This is the value that is stored in the selected
channel.
Here's an example.
1) Click A1.
2) Move the GAIN control to 12 o'clock. The
5
Display will indicate 50, and the dot will light. This
indicates that the gain has been edited, and is dif-
ferent from the gain value in memory.
3) Move the GAIN control to the maximum posi-
tion. The
5
Display will indicate 100, and the dot
will go dark. This indicates that the gain value in
memory is shown in the
5
Display.
* This function is provided for all controls. You can use it to compare the
stored control values with the current value, or to check the contents that
are stored in each channel.
* If you click the MANUAL switch to select manual mode, the position of
every control will correspond to the actual value that determines the sound.
