parameter, scroll to the range you need, then highlight the Coarse Tune parameter. Adjust
Coarse Tune to bring the sample to the proper pitch within that key range. Then scroll back up
to the Key Range parameter, select the next range, and continue as needed.
Here's a fairly important point that may or may not affect your keymap construction. Suppose
you want to build a keymap that uses the same sample in several adjacent key ranges, and you
plan to add a bit of detuning to the samples in each range. You might think that you could build
the keymap first, then go into the Sample Editor and tweak the samples when the keymap is
finished. Yes, but...
Suppose you used the technique we described above to assign a vocal sample whose root was
C 4 to a key range from A 3 to E 4. Then you assigned the same sample to a key range from F 4 to
B 4. You might be surprised to find that when you finished the F 4–B 4 key range and the
Keymap-editor page reappeared, the current key range would not be F 4 to B 4, but A 3 to B 4!
This is because the K2661 automatically merges adjacent key ranges that are identical (this is
done to save memory). Therefore, some parameter must be different in each adjacent key range
you create if you want to build keymaps using the technique we just described. So if you want to
use the same samples in adjacent key ranges with, for example, minor pitch or volume
modification, you should make those changes to the current sample on the Keymap-editor page
before assigning the next range.
Using the Analog Inputs to Trigger Samples
The analog sampling inputs double as one- or two-channel trigger inputs. This allows audio
signals from external sources (such as microphones and tape recorders) to trigger internal
samples. The following steps explain how to use the trigger inputs.
1. Connect cables from the outputs of your external audio source to the analog sampling
2. Enter Program mode, and select the program containing the sample(s) you want to
3. Set the Song-mode Click parameters to match the program you chose:
4. Enter Sample mode, set Src to External, and set Mode to Trigger.
5. Set the trigger threshold:
Now analog input signals will trigger samples in the click program. The sampler's analog
inputs are stereo, so you can trigger samples on two different keys. The left channel will trigger

inputs on the K2661. For details on which cables to use with the analog sampling inputs,

trigger.
Enter Song mode, select the MISC page, and set the Click Channel and Click Program
parameters to the MIDI channel and program number of the program you just chose.
Change the value of the Click Key parameter to define the key number played by the
sequencer's metronome. This indirectly determines what samples are triggered by the
inputs, since the inputs always trigger the samples that are assigned to the first two keys
above the Click Key.
The default Click parameters are Click Channel 16, Click Program 198 Click, and Click
Key C4. (Therefore the default keys triggered by the analog inputs are C
Highlight the Thresh parameter on the SampleMode page, and adjust the input sensitivity
so that your input signal causes smooth triggering. Threshold values approaching -90db
let you trigger the sample using a lower input level, while values approaching -6db
require a greater input level.
